A theory of generalized Donaldson-Thomas invariants. II. Multiplicative identities for Behrend functions

Abstract

This paper has been withdrawn, not because of any errors (that we know of), but because rather than presenting our material as a series of 3 papers, as we originally intended, we have now combined them into one long paper, which is "A theory of generalized Donaldson-Thomas invariants", arXiv:0810.5645v3, June 2009, 181 pages, and this paper has been incorporated into that.
