Title: Geometric Extension Algebras

 

Abstract: Geometric extension algebras are convolution algebras in Borel–Moore homology, or equivalently sheaf-theoretic Ext algebras. Interesting examples include KLR and quiver Schur algebras. We discuss how geometric parity vanishing properties are equivalent to representation-theoretic properties of these algebras. Some applications will be discussed if time permits.
