Title:	 Mickelsson's twisted K-theory invariant and its generalization

Date:	Tue, Mar 05, 2013, 15:30 - 17:00

Place:	Seminar Room A

Abstract:	 Twisted K-theory is a topological K-theory with certain
local coefficients. It became familiar thanks to its ability to
classify Ramond-Ramond charges of D-branes. Mickelsson's invariant is
an invariant of odd twisted K-classes on 3-manifolds. This invariant
detects some subtle information which cannot be captured by the Chern
character. The theme of my seminar is to introduce a reformulation and
some generalizations of the invariant. I also clarify relationship
with the Atiyah-Hirzebruch spectral sequence.
