Séminaire Cirget: «Vector bundles on twistor spaces of hyperkähler manifolds»

Conférencier: Artour Tomberg, University of Western Ontario

Résumé / Abstract: A hyperkähler manifold M comes equipped with a 2-sphere of integrable almost complex structures. The topological product of M with this 2-sphere, which parametrizes these structures at points of M, has a natural integrable almost complex structure, making it into a (non-Kähler) complex manifold, denoted Tw(M) and called the twistor space of M. I will talk about the twistor space Tw(M) and the relationship between stable holomorphic vector bundles on Tw(M) and those on M. This is joint work with Indranil Biswas.
