|Title:||Quantum Deformation Theory|
|Date (JST):||Wed, Aug 25, 2010, 13:00 - 14:30|
This will be the second meeting of the "Costello Series" of the Quantum Deformation Theory seminar.
I will talk about Costello's construction of a derived extension of an open TCFT to an open-closed TCFT and show that it can be computed via Hochschild homology. I will also describe a relation between open TCFTs and Calabi-Yau A_infty-categories. Ref.: Kevin Costello, Topological conformal field theories and Calabi-Yau categories. Adv. Math. 210 (2007), no. 1, 165-214.
