	Closed as an poor imitation of a previously asked question! :-) – Scott Morrison♦ Feb 11 2010 at 5:12
	Well, my question was about the closed string B-model. In any case, I think the open string B-model is supposed to be described by the derived category of coherent sheaves. – Kevin Lin Feb 11 2010 at 8:25
	Hi,so the physical B model is not rigorous because the integral measure is not defined, right? Thanks for help! – mathlover Feb 12 2010 at 17:27
