Abstract: Trace map on deformation quantized algebra leads to the 
algebraic index theorem. We investigate a two-dimensional chiral 
analogue of the algebraic index theorem via the theory of chiral 
algebras developed by Beilinson and Drinfeld. We construct a trace map 
on the elliptic chiral homology of the free beta gamma-bc system using 
the BV quantization framework. As an example, we compute the trace 
evaluated on the unit constant chiral chain and obtain the formal Witten 
genus in the Lie algebra cohomology. This talk is based on joint work 
with Si Li.

/This will be a hybrid seminar. All are very welcome to join either 
online or in person. Venue: Luigi Stasi Seminar Room (ICTP Leonardo Da 
Vinci Building), for those wishing to attend in person./
