Title: Uncertainty Principles Associated to Sets Satisfying the Geometric Control Condition

Title: Polynomial approximation in L^2 of a log-concave weight.
Abstract: Given a measure with exponential moments, it is well known that polynomials are dense in L^2. A natural question is to quantify the rate of approximation for some classes of function, say Lipschitz. Such results are known as Jackson's theorem. We discuss the about log-concave case, especially in dimension one. Joint work with Bo'az Klartag.

Title: Jackson's inequality on the hypercube
Abstract: This talk explores how well real-valued functions on the hypercube can be uniformly approximated by degree-d polynomials. I will present techniques for obtaining upper and lower bounds. As a first application, we show that the reverse Bernstein inequality fails in the tail space L^{1}_{≥0.499n}, improving previous counterexamples in L^{1}_{≥Clog log(n)}. As a second application, we show that no sensitivity theorem holds for bounded-valued functions, even when degree is relaxed to approximate degree. This is a joint work with Paata Ivanisvili and Roman Vershynin.

Title: Discrete Brunn-Minkowski inequality for subsets of the cube
Abstract: The classical Brunn-Minkowski inequality implies that for any two subsets A and B of Euclidean space, the volume of the Minkowski sum A + B is bounded from below by (|A||B|)^{1/2}. This inequality continues to hold in the discrete setting, on the integer lattice with counting measure. The topic of this talk is an optimal sharpening of this inequality when the sets A, B are contained in the cube {0, 1, 2}^d. I will discuss some applications and a useful method for proving inequalities in one variable. This is based on joint work with Paata Ivanisvili, Dmitry Krachun and José Madrid.

Title: Banach-space valued multilinear singular integrals and time-frequency analysis
Abstract: Since the 1960s, Calderón-Zygmund theory has provided a framework for studying singular integral operators that resemble the Hilbert transform, a ubiquitous operator in complex analysis, PDEs, and many other areas of mathematics. In the 1980s, Bourgain and Burkholder characterized the Banach spaces where linear Calderón-Zygmund theory is available through the UMD property—a purely probabilistic condition.
More recently, there has been significant interest in multilinear singular integral operators, which arise e.g. in fractional Leibniz rules and multilinear ergodic theory. However, a complete Banach-space valued theory remains elusive, especially for operators that exhibit stronger singularities than Calderón-Zygmund operators, such as the bilinear Hilbert transform—a prototypical operator of time-frequency type.
We will review the techniques involved in these problems, with emphasis on time-frequency analysis methods, presenting both our current understanding and open directions for extending the theory to the multilinear setting.

Title: Sampling discretization problem
Abstract: Informally speaking, sampling discretization studies how well one can replace the computation of integral Lp norms for a given class of functions, by the evaluation of these functions at a fixed small set of points. On the one hand, such problems are classical. The first results of this type were obtained in 1937 by Marcinkiewicz for Lp-norms, with 1<p< infty, and by Marcinkiewicz-Zygmund for L1-norm for the class of univariate trigonometric polynomials of a fixed degree. On the other hand, the systematic study of sampling discretization has begun only recently.
Let C(Ω), be the space of all continuous functions on some compact subset Ω of R^n, equipped with a Borel probability measure μ. Let X_N be some N-dimensional subspace of C(Ω), let p≥1 , and let 0<ε<1. We aim to determine the smallest integer m for which there exists points x_1, … , x_m in Ω, such that for any f in X_N:
(1-ε) ||f||_p^p ≤ \frac{1}{m} \sum_{1 ≤ j ≤m} |f(x_j)|^p ≤ (1+ε) ||f||_p^p
where ||.||_p denotes the norm on L^p(Ω, μ). Clearly, the number of points m cannot be less than the dimension N of the subspace X_N. We are interested in conditions on the subspace which can guarantee that m can be chosen close to N.
In the talk we shall discuss recent progress and some techniques in this area.

Title: Sharp Strichartz Estimates via Hermite Polynomials and Hypercontractivity
Abstract: We will present an approach to prove sharp inequalities for free-range Schrödinger propagator using a pseudo-conformal transformation (the Lens transform) that reformulates the whole problem as a sort of average hypercontractivity statement in Gauss space We will indicate how to solve this in the even exponent case. We will also explain an old idea from my phd thesis on how to solve the general case via 3-symbol Hamming cube approximations.
Tuesday, November 12, 2024 - from 2:45 to 4:00 pm
Title: Stability in the Banach isometric conjecture for planar sections
Abstract: Banach asked whether a normed space all whose k-dimensional linear subspaces are isometric to each other, for some fixed 2 \leq k < \dim (V), must necessarily be Euclidean. At present, an affirmative answer is known for k=2 (Auerbach-Mazur-Ulam, 1935), all even k (Gromov, 1967), all k=1 \mod 4 but k=133 (Bor-Hernandez Lamoneda-Jimenez Desantiago-Montejano Peimbert, 2021), and k=3 (Ivanov-Mamaev-Nordskova, 2023). These developments, except perhaps the recent resolution of the k=3 case, can be considered spiritual successors to the original argument of Auerbach-Mazur-Ulam for k=2 which is based on a topological obstruction. In this talk, I will present a stable version of their result: if all 2-dimensional linear subspaces are approximately isometric to each other, then the normed space is approximately Euclidean. This talk is based on joint work with Dmitry Faifman.
Thursday, October 31, 2024 - from 2:45 to 4:00 pm
Title: Counting Lattice Points in Ellipsoids and the Central Limit Theorem for Quadratic Forms
Abstract: In this talk we review classical results on lattice point counting problems for ellipsoids and describe in dimensions five and larger some older and recent results on explicit error bounds. We outline their relation to corresponding errors estimates in the multivariate central limit theorem in Probability and the importance of gap principles for bounding Fourier integrals.
Tuesday, October 29, 2024 - from 2:45 to 4:00 pm
Title: Testing monotonicity from quantum data
Abstract: This talk is about testing properties of Boolean functions from data, where it turns out quantum algorithms can have dramatic speedups. We will focus on monotonicity testing. Here, a classical algorithm given access only to uniformly random samples (x,f(x)) requires at least 2^Ω(sqrt(n)) samples to test if f is monotone. On the other hand, we will describe a quantum algorithm for monotonicity testing that requires only poly(n) quantum data, in the form of so-called function states: sum_x |x,f(x) ⟩. We will also prove an n^3/2 lower bound for such quantum algorithms via a careful analysis of certain matrix ensembles. This is one of the first works to consider such lower bound arguments, and we welcome discussion and improvements to our techniques. - Based on joint work with Matthias Caro and Preksha Naik.
Thursday, October 24, 2024 - from 2:15 to 3:30 pm
Title: The zero distribution for Taylor series with random and pseudo-random coefficients
Abstract: We study the local distribution of zeros of Taylor series for different classes of coefficients: random ones (independent, stationary, arithmetic random) and pseudo-random ones (exponential-polynomial, Rudin-Shapiro, Thue-Morse).
Tuesday, October 22, 2024 - from 2:45 to 4:00 pm
Title: Query lower bounds for log-concave sampling
Abstract: A central step in the implementation of probabilistic algorithms is that of sampling from known, complicated probability distributions: Given the density of a random variable (for example, as a black-box function that one can query) generate samples from a random variable that has a distribution "similar enough" to the given one. Significant effort has been devoted to designing more and more efficient algorithms, ranging from relatively simple algorithms, such as rejection sampling, to increasingly sophisticated such as Langevin or diffusion based models. In this talk we will focus on the converse question: Finding universal complexity lower bounds that no algorithm can beat. We will do so in the case when the log-density is a strictly concave smooth function. In this case we will be able to construct tight bounds in low dimension using a modification of Perron's sprouting construction for Kakeya sets. Based on joint work with Sinho Chewi, Jerry Li, Chen Lu and Shyam Narayanan.

Title: Global maximizers for spherical restriction
Abstract: We prove that constant functions are the unique real-valued maximizers for all L^2-L^{2n} adjoint Fourier restriction inequalities on the unit sphere S^{d-1}\subset R^d, d \in {3,4,5,6,7}, where n\geq 3 is an integer. The proof uses tools from probability theory, Lie theory, functional analysis, and the theory of special functions. It also relies on general solutions of the underlying Euler--Lagrange equation being smooth, a fact of independent interest which we discuss. We further show that complex-valued maximizers coincide with nonnegative maximizers multiplied by the character e^{i\xi\cdot\omega}, for some \xi, thereby extending previous work of Christ & Shao (2012) to arbitrary dimensions d\geq 2 and general even exponents.
Tuesday, October 15, 2024 - from 2:45 to 4:00 pm
Title: The L^p theory for outer measure spaces
Abstract: The theory of L^p spaces for outer measures, or outer L^p spaces, was introduced by Do and Thiele, as tool in the proof of estimate for multilinear forms arising in the context of harmonic analysis (Calderón-Zygmund theory, time-frequency analysis). To this end, they developed the theory in the direction of the interpolation properties of the spaces, such as Hölder’s inequality and Marcinkiewicz interpolation. However, the outer L^p spaces can be defined in a broader generality of settings, for example extending the classical notion of mixed L^p spaces on the Cartesian product of measure spaces. In this talk we expose further developments in the theory of the outer L^p spaces, focusing on their Banach space properties, such as Fubini’s theorem, Köthe duality, and Minkowski’s inequality.
Thursday, October 3, 2024 - from 2:45 to 4:00 pm
Title: Bounded functions with small tails are Juntas
Abstract: There seems to be some recent interest in structural results concerning functions whose Fourier transform is mostly supported on `low-degrees' while their range is restricted to a specific set. This is at least partly motivated by applications to Theoretical Computer Science. In this talk I will go over a not-so-recent result with this theme, which shows that a function f over the discrete hypercube whose Fourier representation is `mostly' of low degree and which obtains values in the (continuous) segment [-1,1] must be close to a junta, namely it can be approximated by only looking at a constant number of input-coordinates. The proof goes by showing a large-deviation lower bound for low degree functions that uses some tricks that may be of interest. If time permits I may also talk about some improvements to our result made by O’Donnell and Zhao. Joint work with Irit Dinur, Ehud Friedgut, and Ryan O'Donnell.
Tuesday, October 1, 2024 - from 2:45 to 4:00 pm
Title: Weighted inequalities for the Fourier transform
Abstract: In this talk we discuss inequalities for the Fourier transform between weighted Lebesgue spaces and their connection with an interpolation technique due to Calderón.
Thursday, September 26, 2024 - from 2:45 to 4:00 pm
Title: On the spectral norm of Rademacher matrices
Abstract: We will discuss two-sided non-asymptotic bounds for the mean spectral norm of nonhomogenous weighted Rademacher matrices. We will present a lower bound and show that it may be reversed up to log log log n factor for arbitrary n×n Rademacher matrices. Moreover, the triple logarithm may be eliminated for matrices with 0,1-coefficients.
Tuesday, September 24, 2024 - from 2:45 to 4 pm
Title: On Spherical Covariance Representations
Abstract: We first motivate the study of covariance representations by surveying preceding results in the Gaussian space. Their spherical counterparts are then derived thereby allowing applications to the spherical concentration phenomenon. The applications include second order concentration inequalities. The talk is based on joint work with Sergey Bobkov.
Thursday, September 12, 2024 - from 2:45 to 4:00 pm
Title: On the asymptotics of the optimal constants in the Khinchine-Kahane inequality
Abstract: Let us consider a sequence of indepenedent symmetric +/-1 random variables, often called the Rademacher system. A linear combination of these random variables is a real random variable called a (weighted) Rademacher sum. There are also vector-valued Rademacher sums, in which the real coefficients in the linear combination are replaced by vectors from some normed linear space. Rademacher sums, both real and vector-valued, have been studied for more than 100 years now. In the talk, classical moment inequalities for Rademacher sums will be described, going back to Khinchine (1923) and Kahane (1964), as well as some more recent results.

Description: The interaction between learning theory and harmonic analysis was emphasized by mathematics of quantum computing. One of the outstanding open problems in this area concerns the sharp estimates in Bohnenblust-Hille inequality that generalizes a celebrated Littlewood’s lemma.
How to learn (with small error and with large probability) a complicated function or a very large matrix in a relatively small number of random (quantum) queries? Of course, there should be some Fourier type restrictions on a function (a matrix) to have a reasonable answer to this.
The “classical” way of learning (Boolean) functions comes from very sophisticated extensions of theorems of Kahn—Kalai—Linial type. In those results the interplay between maximal influence and heavy Fourier tails is the main technique. Maximal influence should be large if the `tail’ is small. However, recently another approach that is hinged on Bohnenblust—Hille inequality appeared. The school will cover the classical maximal influence approach to `probably approximately correct' (PAC) learning as well as the recent achievements using Bohnenblust—Hille inequality and its quantum counterpart.

Harmonic analysis on the hypercube has long found exciting applications in theoretical computer science, in areas as diverse as learning theory, voting theory, and computational complexity theory. And TCS has also inspired challenging new questions in analysis, often leading to new perspectives on familiar topics. Indeed, this connection is only deepening as quantum computing, machine learning, and other areas of TCS expand to spaces beyond the hypercube. Talks in this workshop will focus on such connections recently uncovered, techniques in use today, and conjectures old and new. We hope it can also be an invitation to the topic for a harmonic analysis audience, thanks to additional introductory talks scheduled.
