Let $k$ be a fixed positive integer. Myerson (and others) asked how small the modulus of a non-zero sum of $k$ roots of unity can be. If the roots of unity have order dividing $N$, then an elementary argument shows that the modulus decreases at most...

The "P vs. NP" problem, formulated by computer theorists in the 1970s, quickly became a central outstanding problem of science and mathematics. In this talk I will attempt to describe its mathematical, scientific and philosophical content. I will...

I hope to talk more about how to find generators for Fukaya categories using symplectic version of the minimal model program in examples such as symplectic quotients of products of spheres and moduli spaces of parabolic bundles.

Considering some special examples as algebras of quivers I will give an informal introduction to a field of geometric realizations of noncommutative and derived varieties.

Rank gives a natural filtration on representations of classical groups. The eta correspondence provides a clean description of a natural family of representations of a given rank, subject to certain bounds. There is evidence that this construction...

Suppose you have a finite group G and you want to study certain related structures (e.g., random walks, Cayley graphs, word maps, etc.). In many cases, this might be done using sums over the characters of G. A serious obstacle in applying these...

Continuing from February 28, I will attempt to explain Costello's set up of the problem of perturbative quantization of a gauge theory in the Batalin-Vilkovisky formalism, thus allowing us to formulate the main results of Costello and Li.
