%0 Journal Article %T A Note on Support in Triangulated Categories %A Aaron Bergman %J Mathematics %D 2008 %I arXiv %X In this note, I define a notion of a compactly supported object in a triangulated category. I prove a number of propositions relating this to traditional notions of support and give an application to the theory of derived Morita equivalence. I also discuss a connection to supersymmetric gauge theories arising from D-branes at a singularity. %U http://arxiv.org/abs/0804.3986v1
