Titre A physicist viewpoint on the cohomology of quiver moduli
Horaire10:30 à 11:30
RésumeModuli spaces of quiver representations naturally appear in physics in the context of the dynamics of supersymmetric black holes. Based on physics intuition, I will propose concrete formulae for computing the Poincaré polynomial of quiver moduli spaces in terms of new invariants which do not depend on the stability parameters. Based on joint work with S. Alexandrov, J. Manschot, Ashoke Sen [arXiv: \href{https://arxiv.org/pdf/1207.2230.pdf}{1207.2230}, \href{https://arxiv.org/pdf/1404.7154.pdf}{1404.7154},\href{https://arxiv.org/pdf/1804.06928.pdf}{1804.06928}]
