PrIncipal quiver Grassmannians: conjectures
Stanislav Fedotov, Evgeny Feigin
Let and be a projective and an injective representations of a Dynkin quiver. We consider quiver Grassmannians of subrepresentations of dimension inside representat…
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…
Global positroid varieties
Evgeny Feigin
Positroid subvarieties of complex Grassmannians are the images of the Richardson subvarieties of the full flag varieties under the natural projection map. Positroid varieties admit…
Type A algebraic coherence conjecture of Pappas and Rapoport
Evgeny Feigin, an appendix in collaboration with Andrey Karenskih
The Pappas--Rapoport coherence conjecture, proved by Zhu, states that the dimensions of spaces of sections of certain line bundles coincide. The two sides of the equality correspon…
