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…

Categorification of quiver diagonalization and Koszul algebras
Vladimir Dotsenko, Evgeny Feigin, Piotr Kucharski +1
In earlier work of three of the authors of the present paper, a supercommutative quadratic algebra was associated to each symmetric quiver, and a new proof of positivity of motivic…
