Ayako Kubota (Saitama University) : The invariant Hilbert scheme associated with a torus action

Séminaire « Géométrie algébrique »
Salle Kampé de Feriet (Bâtiment M2, 1er étage)

We consider the invariant Hilbert scheme associated with a torus action and study its relationship with the GIT quotients arising from variation of GIT.

As examples, we examine certain cases of toric hyperkähler quotients and type A nilpotent orbit closures.

This talk is based on joint work with Yasunari Nagai.
