Seventy Seventh Meeting of the Transpennine Topology Triangle Manchester 2011
Date and Location
Monday 10 January 2011
The talks will take place in the Frank Adams Seminar Rooms 1 and 2, on the first floor of the Alan Turing Building. This is on the east side of the campus, off Upper Brook Street and about 100m south of the junction with Booth Street East. It is about 15 minutes walk from Piccadilly station, through the old UMIST campus and under the Mancunian Way. The building is number 46 on the University Campus map.
Participants will meet for coffee from 1100AM onwards in the Atrium Bridge Common Room; the Frank Adams Rooms open into the common room.
Lunch may be taken in any of several local venues (such as the cafe in the atrium, or the vegetarian "On the Eighth Day", for example), and we expect to visit a nearby restaurant for early-evening dinner.
Programme
- 11.00-11.30: COFFEE (Atrium Bridge)
- 11.30-12.30: Michael Wiemeler (University of Manchester)
Actions of non-abelian Lie-groups on quasitoric manifolds
For a smooth manifold M, the smooth symmetry degree N_s(M) of M is defined to be the maximum dim G for compact Lie groups G acting smoothly and almost effectively on M. In this talk we establish upper bounds for the symmetry degree of certain quasitoric manifolds.
- 12.30-2.30: LUNCH
- 2.30-3.30: S S Khare (North-Eastern Hill University, Shillong)
Vector fields on certain manifolds
- 4.00-5.00: Samik Basu (University of Copenhagen)
R-module Thom spectra
Let R be a commutative ring spectrum. Given a map f from X to BGL_1R one can construct the R-module Thom spectrum Th(f). If f is a map of loop spaces, Th(f) has the structure of an R-algebra, and the R-algebra Topological Hochschild Homology can also be described as a Thom spectrum. Using this, one can make explicit computations of Topological Hochschild Homology.
Travel support
Everyone who wishes to participate is welcome, particularly postgraduate students. We shall operate the usual criterea for assistance with travel expenses, but beneficiaries will need to complete the standard forms, and should come armed with NI numbers and details of UK bank accounts. Please email Nige Ray if you expect to attend, so that we can cater for appropriate numbers.
