I’ll describe a circle of ideas that links Schubert polynomials with representation theory, via some configuration spaces studied by Magyar (and which include Schubert’s famous space of complete triangles). Most of the geometric connections were...

Postnikov's divided symmetrization, introduced in the context of volume polynomials of permutahedra, possesses a host of remarkable ``positivity'' properties. These turn out to be best understood using a family of operators we call quasisymmetric...

The Oppenheim conjecture, proved by Margulis in 1986, states that for a non-degenerate indefinite irrational quadratic form Q in $n \geq$ 3 variables, the image set $Q(Z^n)$ of integral vectors is a dense subset of the real line. Determining the...

In 2021 Avi gave a talk titled “Linear spaces of matrices” (see https://www.youtube.com/watch?v=H1H0OkZfZXw). As shown there, the study of linear spaces of matrices (which we call matrix spaces) arises naturally (and independently) in many different...

Semiclassical measures are a standard object studied in quantum chaos, capturing macroscopic behavior of sequences of eigenfunctions in the high energy limit. They have a long history of study going back to the Quantum Ergodicity theorem and the...

The lateral periodic condition has been imposed canonically and investigated extensively in the study of a channel flow, which unfortunately is not compatible with either the celebrated Reynolds' experiment or the self-similar Blasius boundary layer...

Originally introduced as analogs of symmetric spaces for  groups over non-archimedian fields buildings have proven useful in various areas by now. In this talk I will introduce (Bruhat-Tits) buildings,  combinatorial toolkits to study them and their...

Two central results in modern complexity theory can be summed up as follows:

1. Everything provable is provable in zero knowledge (NP ⊆ CZK); and
2. Everything provable is locally checkable (NP = PCP[log n, 1]).

In a pair of recent works, we show how to...
