Actions of non-abelian Lie-groups on quasitoric manifolds

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.

R-module Thom spectra

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.
