1. # MSRI Evans Talk: Finite dimensional Banach Spaces

Location: 60 Evans Hall, UC Berkeley
Speakers: Pierre Colmez (Institut de Mathématiques de Jussieu)

The algebraic closure of the field ${\bf Q}_p$ of $p$-adic number is infinite dimensional over ${\bf Q}_p$, hence its completion ${\bf C}_p$ is also infinite dimensional.  I will describe objects that can be thought of as finite dimensional vector spaces over ${\bf C}_p$ up to finite dimensional ${\bf Q}_p$-vector spaces and explain what kind of properties they have. I will end up with some recent applications.

2. # Number Theory Seminar: Wild ramification and K(π; 1) spaces

Location: 740 Evans Hall

Speaker: Piotr Achinger

A smooth variety in characteristic zero is Zariski-locally a K(π; 1) space, i.e., has trivial higher homotopy groups. This fact is of crucial importance in Artin’s proof that l-adic cohomology agrees with singular cohomology over C. The characteristic p variant of this is not known—we do not even know whether the affine plane is a K(π; 1) in positive characteristic! I will show how to reduce this question to a “Bertini-type” statement regarding wild ramification of l-adic local systems on affine spaces, which might be of independent interest. I will verify this statement in the special case of local systems of rank 1 and speculate on how one might treat the general case.
