Invariant deformations of orbit closures in $sl_{n}$

Sébastien Jansou, Nicolas Ressayre

We study deformations of orbit closures for the action of a connected semisimple group $G$ on its Lie algebra $g$ , especially when $G$ is the special linear group. The t…

The invariant Quot scheme

Sebastien Jansou

Given an affine scheme X with an action of a reductive group G and a G-linearized coherent sheaf M, we construct the ``invariant Quot scheme'' that parametrizes the quotients of M…

Deformations of cones of primitive vectors

Sebastien Jansou

For a complex connected reductive group G, we classify the simple modules whose cone of primitive vectors admits a nontrivial G-invariant deformation. We relate this classification…
