Mini-Symposium on Topology

Is the abstract mathematics of topology applicable to the real world?
Robert D. MacPherson; Randall D. Kamien; Raúl Rabadán
5:30pm|Wolfensohn Hall

Topology is the only major branch of modern mathematics that wasn't anticipated by the ancient mathematicians. Throughout most of its history, topology has been regarded as strictly abstract mathematics, without applications. However, illustrating...

Motivic Cohomology

An Approach to the Conservation of the Nearby Motive Functor
2:00pm|S-101

We present a program to prove the following conjecture: Let $S$ be the spectrum of a DVR of equi-characteristic zero with field of fraction $K$ and residue field $k$. The functor (associated to the choice of a uniformizing) $\Psi:DM_{gm}(K) \to DM_...

The Syntomic Regulator for K_1 of Surfaces
2:00pm|S-101

We give an explicit formula for the syntomic regulator of certain elements in the first algebraic K-theory group of a smooth complete surface over the ring of integers of a p-adic field. The formula uses the theory of Coleman integration and the...

Arithmetic Cohomology and Special Values of Zeta-Functions (after Geisser)
11:00am|S-101

Geisser gives conjectured formulas for special values of zeta-functions of varieties over finite fields in terms of Euler characteristics of arithmetic cohomology (an improved version of Weil-etale cohomology). He then proves these formulas under...

Bass' NK Groups and cdh-Fibrant Hochschild Homology
11:00am|S-101

By definition, NK_0(R) is K_0(R[t]) modulo K_0(R). We give a formula for this group when R is of finite type over a field of characteristic zero. The group is bigraded and determined by its typical pieces, which are the cdh cohomology groups H^p(R...
