Titre Around Donaldson-Thomas invariants of symmetric quivers
Résumé I shall talk about two new ways of understanding refined Donaldson-Thomas invariants of symmetric quivers (defined by Kontsevich and Soibelman via the cohomological Hall algebras). One of them is a result of my work with Evgeny Feigin and Markus Reineke, where the upshot are certain (super)commutative algebras with quadratic relations whose multigraded characters can be used to give new interpretations of refined Donaldson-Thomas invariants. The other is a result of my work with Sergey Mozgovoy, where the same invariants obtain an interpretation in the context of vertex algebras.
