Gravitational instantons and Hermitian geometry
Ponente: Olivier Biquard (Sorbonne Université, Paris)Fecha: miércoles 22 de octubre de 2025 - 11:30Lugar: Aula Naranja, ICMAT
Resumen:
Gravitational instantons are finite energy Ricci flat complete 4-manifolds. They are completely understood in the Kähler setting, but remain mysterious in general, with old questions going back to the 90's. There is a renewed activity in the field at the moment, and I shall explain recent results using Hermitian geometry.
