Bundle gerbes for Chern-Simons and Wess-Zumino-Witten theories
Alan L. Carey, Stuart Johnson, Michael K. Murray +2
We develop the theory of Chern-Simons bundle 2-gerbes and multiplicative bundle gerbes associated to any principal -bundle with connection and a class in $H^4(BG, \ZZ)$ for a co…
On the relationship of gerbes to the odd families index theorem
Alan L. Carey, Bai-Ling Wang
The goal of this paper is to apply the universal gerbe of \cite{CMi1} and \cite{CMi2} to give an alternative, simple and more unified view of the relationship between index theory…
L^2 torsion without the determinant class condition and extended L^2 cohomology
M. Braverman, A. Carey, M. Farber +1
We associate determinant lines to objects of the extended abelian category built out of a von Neumann category with a trace. Using this we suggest constructions of the combinatoria…
Amenability of the Gauge Group
Alan Carey, Hendrik Grundling
Let G be one of the local gauge groups C(X,U(n)), C^\infty(X,U(n)), C(X,SU(n)) or C^\infty(X,SU(n)) where X is a compact Riemannian manifold. We observe that G has a nontrivial gro…
