Exponential Functors, R-Matrices and Twists

Ulrich Pennig

In this paper we show that each polynomial exponential functor on complex finite-dimensional inner product spaces is defined up to equivalence of monoidal functors by an involutive…

Twisted K-theory with coefficients in C*-algebras

Ulrich Pennig

We introduce a twisted version of -theory with coefficients in a -algebra , where the twist is given by a new kind of gerbe, which we call Morita bundle gerbe. We use th…

The classification of non-local chiral CFT with c<1

Y. Kawahigashi, R. Longo, U. Pennig +1

All non-local but relatively local irreducible extensions of Virasoro chiral CFTs with c<1 are classified. The classification, which is a prerequisite for the classification of loc…
