Indranil Biswas (Shiv Nadar University) : A Belyi-type criterion for vector bundles on curves defined over a number field

Séminaire « Géométrie algébrique »

21 mai 14:00 - 15:00 Salle Kampé de Feriet (Bâtiment M2, 1er étage)

Let X be a smooth projective curve defined over the algebraic closure of the field of rational numbers and X' its base change to the complex numbers. Given a vector bundle E over X', we give a criterion for E to be a vector bundle on X. This is a joint work with S. Gurjar.
