DESCRIPTION:Speaker: Michela Varagnolo (Université de Cergy-Pontoise)\n\nTi
tle: K theoretic Hall algebras and coherent categorification of quantum gro
ups\n\nAbstract: I will explain an isomorphism between the positive half o
a quantum toroidal group and the K-theoretic Hall algebra of a preprojectiv
e algebra of affine type. There is an analogue result in the finite type ca
se. For type $A_1$ this allows to propose a coherent categorification of th
e quantum affine $sl(2)$. Surprisingly it may be computed using KLR algebra
s. The talk is based on two joint works\, one with E. Vasserot\, the other
with P. Shan and E. Vasserot.
