Colloquium

We discuss how something remarkably similar to Hall’s marriage theorem appears naturally in context of a conjecture of Grothendieck in algebraic geometry, and how this is useful to prove some long-standing problems in discrete geometry. For instance, I will prove…

Integral representations are a fundamental tool in the study of automorphic L functions. One of these constructions, developed by Piatetski-Shapiro and Rallis in the late 80s, produced the standard L function for any cuspidal representation of a classical group, or…

Many of us are familiar with the classical fact that the orbit of an irrational rotation of the circle is equidistributed, meaning that the fraction of time spent in any given arc is asymptotically equal to the length of the…

Polynomial functors were introduced in an algebraic setting by Eilenberg and Mac Lane around 1954 (but implicitly were present already in the work of Schur circa 1900). Since the advent of the calculus of functors (Tom Goodwillie in the 1990-ies),…
