A related thing is quantum master equation, what's its use in mathematics? Any reference or background? Thanks!</p> http://mathoverflow.net/questions/30373/does-the-deligne-mumford-space-module-s-n-action-have-a-fundamental-chain Does the Deligne-Mumford space module $S_{n}$ action have a fundamental chain? mathphysics 2010-07-03T05:20:20Z 2010-07-03T21:32:12Z <p>Does the Deligne-Mumford space (without ordering for marked points) $\bar M_{g,n}/S_{n}$ has fundamental chain in signular simplicial chains? (because I read Costello's paper GW potential to TCFT, as a orbifold,what's the fundamental chain?)</p>
