Every word in a free group induces a probability distribution on every finite group by substituting the letters of w by uniformly random elements of the group. The connection between such distributions on the symmetric group and the poset of...

Pretannakian categories, that is k-linear abelian categories with finite dimensional Hom groups, given with a commutative and associative tensor product, with a unit object (such that End(1)=k) and duals, can be viewed as generalizations of linear...

What can be said about a system of polynomial equations over a finite field if its number of solutions deviates from that of a random system? Answer: Roughly, one of the polynomials (or a linear combination thereof) can be written in terms of “few”...

In a landmark paper in 1992, Stanley developed the foundations of what is now known as the Kazhdan--Lusztig--Stanley (KLS) theory. To each kernel in a graded poset, he associates special functions called KLS polynomials. This unifies and puts a...

We heard last week in Daoji's talk about positroid varieties, which are subvarieties in the Grassmannian defined by cyclic rank conditions, and which are related to Schubert varieties. In this talk, we will provide a criterion for whether positroid...

In this talk we will discuss some recent progress on some questions in extremal combinatorics and in multiparty communication complexity.

We will also discuss some general connections between the two fields, emphasizing how certain problems (e.g...
