Loop Grassmannians of quivers and affine quantum groups

12 Nov 2020 Mirkovic Ivan Yang Yaping Zhao Gufang

We construct for each choice of a quiver $Q$, a cohomology theory $A$ and a poset $P$ a "loop Grassmannian" $\mathcal{G}^P(Q,A)$. This generalizes loop Grassmannians of semisimple groups and the loop Grassmannians of based quadratic forms... (read more)
