DESCRIPTION:Speaker: Ahsan Khan (Harvard)\n\nTitle: Poisson Vertex Sigma Mo
 dels\n\nAbstract: I will discuss a generalization of the two-dimensional P
 oisson sigma model to a holomorphic-topological field theory in three dime
 nsions. It is defined from the data of a Poisson vertex algebra and when s
 pecialized to well-known PVAs\, the field theory can be identified with fi
 eld theories such as Chern-Simons theory and (higher spin) gravity. I'll e
 xplain how PVA modules correspond to line defects in this theory\, and fin
 ally\, I'll aim to explain how this field theory sheds light on the deform
 ation quantization problem of Poisson vertex algebras.\n\nZoom: https://mi
