Geometric construction of the global base of the quantum modified algebra of affine GL_N
O. Schiffmann, E. Vasserot
We prove that the global base of the modified quantum algebra of affine GL_N is compatible with the intersection cohomology base of the convolution algebra of the affine flag varie…

On the K-theory of the cyclic quiver variety
Michela Varagnolo, Eric Vasserot
We compute the convolution product on the equivariant K-groups of the cyclic quiver variety. We get a q-analogue of double-loop algebras, closely related to the toroidal quantum gr…
