#### Multiplicative norms in equivariant and motivic homotopy theory

###### Tsutomu Okano (UIUC Math)

Abstract: The equivariant multiplicative norm construction has proven to be useful in the work of Hill Hopkins Ravenel. It can also be used to formulate genuine equivariant commutative ring spectra. I will give an overview of these ideas and discuss their connection with motivic homotopy theory.

#### Cohomology theories in Algebraic Geometry

###### Christopher Dodd   [email] (Department of Mathematics, University of Illinois at Urbana-Champaign)

Abstract: I’ll give a (mostly) self contained intro to the words in the title- I’ll explain what is a cohomology theory, and why algebraic geometers (as opposed to topologists) are interested in them. At the end I’ll try to say a few words about the modern state of the field.
