Canonical bases and quiver varieties
M. Varagnolo, E. Vasserot
We prove the existence of canonical bases in the K-theory of quiver varieties. This existence was conjectured by Lusztig.

Vertex algebras and the formal loop space
M. Kapranov, E. Vasserot
We introduce an algebro-geometric version of the free loop space for any scheme X of finite type. This is an ind-scheme of ind-infinite type containing the scheme of formal germs o…

Perverse sheaves and quantum Grothendieck rings
Michela Varagnolo, Eric Vasserot
We define a quantum analogue of the Grothendieck ring of finite dimensional modules of a quantum affine algebra of simply laced type. The construction is based on perverse sheaves…
