K-theoretic Hall algebras for quivers with potential
Speaker(s): Tudor Padurariu
Abstract: Given a quiver with potential, Kontsevich-Soibelman constructed a Hall algebra on the cohomology of the stack of representations of (Q,W). In particular cases, one recovers positive parts of Yangians as defined by Maulik-Okounkov. For general (Q,W), the Hall algebra has nice structure properties, fo... read more
