Extremality of principal quiver Grassmannians
Giovanni Cerulli Irelli, Evgeny Feigin, Markus Reineke
We study families of quiver Grassmannians, parametrizing subrepresentations of representations of Dyn\-kin quivers, which are naturally associated to a projective and an injective…

From brick manifolds to Grassmannians of bimodules
Evgeny Feigin, Markus Reineke
We study a class of Grassmannians of sub-bimodules over the path algebras of quivers. Our quiver Grassmannians include Escobar's brick manifolds as well as Labelle's generalization…

Intersection cohomology of moduli spaces of vector bundles over curves
Sergey Mozgovoy, Markus Reineke
We compute the intersection cohomology of the moduli spaces of semistable vector bundles having rank and degree over a curve. We do this by relating the Hodge-Del…
