U. Haifa Topology & Geometry seminar: Sunday, May 8, 2022. Speaker: Sourav Das (Haifa). Title: “Title: Higgs bundles on nodal curves”.
Time: 17:00 (Israel Time)
Location: On Zoom
In I987 Nigel Hitchin proved that the moduli space of Higgs bundles on a smooth projective curve (of genus greater than equal to 2) has a natural symplectic structure. In this talk I will briefly recall a few features of the moduli space. Then I will discuss the moduli spaces of Higgs bundles on nodal curves and how they are related to the moduli spaces of Higgs bundles on smooth curves via nice degenerations. I will also show that there is a relative log-symplectic structure on such a degeneration.
