|Speaker:||Yoshitake Hashimoto (Tokyo City Univ.)|
|Title:||Conformal Field Theory Associated to C2-cofinite Vertex Operator Algebras (joint with Professor Akihiro Tsuchiya)|
|Date (JST):||Sat, May 26, 2012, 13:30 - 15:00|
|Place:||Seminar Room A|
In this talk, we construct a sheaf of coinvariants on a base space of families of stable curves associated to a C2-cofinite Vertex Operator Algebra (VOA), and discuss the behavior of the sheaf for degeneration of curves (factorization). We give a review on a VOA, C2-cofiniteness, the Lie algebra and the associative algebra associated to a VOA, and the regular bimodule.
|Remarks:||Akihiro Tsuchiya was a starting member of IPMU in mathemtics and has been a principal investigator in mathematics 2008-2011. He retired from IPMU in March 2012. We thank him for his contributions to start mathematics at IPMU. We plan to have his last lecture at IPMU as follows. All are welcome.
