# TTT47: Sheffield

Department of Pure Mathematics, the University of Sheffield.

This was a working meeting with the usual time for participant discussion.

## Date

23 November 2004

## Speakers

Jonathan Barker (Southampton)

psi^3 as an upper triangular matrix'

Constantin Teleman (Cambridge)

Toward the Gromov-Witten K-theory of BG

Frank Neumann (Leicester)

On the algebraic K-theory of the category of unstable modules over the Steenrod algebra

## Abstracts

Frank Neumann: Using the Gabriel-Krull filtration, we construct a spectral sequence of homological type converging to the algebraic K-theory of the noetherian objects in the category of unstable modules over the Steenrod algebra. This is in direct analogy with the Brown-Gersten-Quillen spectral sequence converging to the algebraic K-theory of a noetherian scheme via the codimension of support filtration.

The meeting was partially supported by a Scheme 3 grant from the London Mathematical Society.
