1. # Eisenbud Seminar: Commutative Algebra and Algebraic Geometry

Location: 939 Evans Hall
Speakers: Winfried Bruns (Universität Osnabrück), Bernd Sturmfels (UC Berkeley Math Faculty)

Commutative Algebra and Algebraic Geometry

Tuesdays, 3:45-6pm in Evans 939

organizer: David Eisenbud

Date: Nov 25

3:45 Bernd Sturmfels: The Hurwitz Form of a Projective Variety

The Hurwitz form of a variety is the discriminant that characterizes linear spaces of complementary dimension which intersect the variety in fewer than degree many points. We study computational aspects of the Hurwitz form, relate this to the dual variety and Chow form, and show why reduced degenerations are special on the Hurwitz polytope.

5:00 Winfried Bruns: Maximal minors and linear powers

Abstract: We say that an ideal I in a polynomial ring S has linear powers if all the powers of I have a linear free resolution. We show that the ideal of maximal minors of a sufficiently general matrix with linear entries has linear powers. The required genericity is expressed in terms of the heights of the ideals of lower order minors. In particular we prove that all ideals defining rational normal scroll have linear powers. (This is joint work with Aldo Conca and Matteo Varbarao, to appear in J. Reine Angew. Math.)

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.

7. # 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.
