Calabi-Yau, Batalin-Vilkovisky, and all that

Uli Kraehmer (U Glasgow)

Wednesday 20th April, 2011 16:00-17:00 204


This will be an update on our (= Niels Kowalzig and myself) ongoing project to understand the structure of the cohomology ring of a Hopf algebroid (or of an abelian monoidal category if you wish to be more abstract). I will recall our generalisation of cyclic homology to that context, and then speak about noncommutative differential calculi in the sense of Nest-Tamarkin-Tsygan.
