Spectral Sequence Computation of Higher Twisted K-Groups of SU(n)

David E. Evans, Ulrich Pennig

Motivated by the Freed-Hopkins-Teleman theorem we study graded equivariant higher twists of K-theory for the groups G=SU(n) induced by exponential functors. We compute the ra…

Equivariant higher twisted K-theory of SU(n) for exponential functor twists

David E. Evans, Ulrich Pennig

We prove that each exponential functor on the category of finite-dimensional complex inner product spaces and isomorphisms gives rise to an equivariant higher (ie. non-classical) t…

A noncommutative model for higher twisted K-Theory

Ulrich Pennig

We develop a operator algebraic model for twisted K-theory, which includes the most general twistings as a generalized cohomology theory (i.e. all those classified by the unit sp…

Twisted K-theory with coefficients in C*-algebras

Ulrich Pennig

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