High Energy Physics - Theory

Title: Twisted K-theory and K-theory of bundle gerbes

Authors: P. Bouwknegt (1), A. L. Carey (1), V. Mathai (1 and 2), M. K. Murray (1), D. Stevenson (1) ((1) University of Adelaide, (2) MIT)
Abstract: In this note we introduce the notion of bundle gerbe K-theory and investigate the relation to twisted K-theory. We provide some examples. Possible applications of bundle gerbe K-theory to the classification of D-brane charges in non-trivial backgrounds are discussed.
Comments: 29 pages, corrected typos, added references, included new section on twisted Chern character in non-torsion case
Subjects: High Energy Physics - Theory (hep-th); K-Theory and Homology (math.KT)
