In how many points does a curve in the plane intersect a random straight line? The answer to this question is an invariant of the curve called "degree". The notion of degree extends to higher dimensional shapes that are defined in terms of polynomials (varieties) and it is a…

Abstract: The talk will be an introduction to the Langlands program and to some of the preoccupations of contemporary algebraic number theory.I will concentrate on the recent breakthrough of Vincent Lafforgue in defining a Langlands correspondence for reductive…

Abstract: A pasture is, roughly speaking, a field in which addition is allowed to be both multivalued and partially undefined. I will describe a theorem about univariate polynomials over pastures which simultaneously generalizes Descartes’ Rule of Signs and the theory of…

Abstract: A group is coherent if every finitely generated subgroup is finitely presented, and incoherent otherwise. Many well-known groups are coherent: free groups, surface groups, and the fundamental groups of compact 3-manifolds. We consider groups of the form $F_m \by F_n$ or $S_g \by F_n…

Abstract: The logarithm is unique, up to a multiplicative constant, continuous function satisfying the addition law:ln (xy)= ln x + ln y. It is also the integral of dt/t from 1 to x.
The quest for understanding of integrals was and is one of the main driving…

Abstract: Many questions in analysis and geometry lead to problems of quasiconformal geometry on non-smooth or fractal spaces. For example, there is a close relation of this subject to the problem of characterizing fundamental groups of hyperbolic 3…

Cell migration is a fundamentally important phenomenonunderlying wound healing, tissue development, immune responseand cancer metastasis. Understanding basic physics of thecell migration presented a great challenge until, in the lastthree decades, a combination of biological,…
