Quiver Grassmannians and degenerate flag varieties
Giovanni Cerulli Irelli, Evgeny Feigin, Markus Reineke
Quiver Grassmannians are varieties parametrizing subrepresentations of a quiver representation. It is observed that certain quiver Grassmannians for type A quivers are isomorphic t…
Symplectic degenerate flag varieties
Evgeny Feigin, Michael Finkelberg, Peter Littelmann
Let $\SF^a_λ$ be the degenerate symplectic flag variety. These are projective singular irreducible $\bG_a^M$ degenerations of the classical flag varieties for symplectic group $Sp_…
Degenerate flag varieties of type A: Frobenius splitting and BW theorem
Evgeny Feigin, Michael Finkelberg
Let $\Fl^a_\la$ be the PBW degeneration of the flag varieties of type . These varieties are singular and are acted upon with the degenerate Lie group . We prove th…
Degenerate flag varieties and the median Genocchi numbers
Evgeny Feigin
We study the $\bG_a^M$ degenerations $\Fl^a_\la$ of the type flag varieties $\Fl_\la$. We describe these degenerations explicitly as subvarieties in the products of Grassmanian…
