%0 Journal Article %T On the tensor structure of BRST differential and it's application %A Jining Gao %J Mathematics %D 2008 %I arXiv %X In this paper,we compute tensor structure of BRST differential and use this tensor representation we give out $CL_{\infty}$ algebra differential and $GA_{\infty}$ differential which are generalization of Chevalley-Eilenberg differential and Hochchild differential respectively. %U http://arxiv.org/abs/0807.2072v1
