We provide some examples. Possible applications of bundle gerbe K-theory to the classification of D-brane charges in non-trivial backgrounds are discussed.29 pages, corrected typos, added references, included new section on twisted Chern character in non-torsion caseHigh Energy Physics - TheoryK-Theory and Homologytext
