Symplectic Grassmannians and Cyclic Quivers
Evgeny Feigin, Martina Lanini, Matteo Micheli +1
The goal of this paper is to extend the quiver Grassmannian description of certain degenerations of Grassmann varieties to the symplectic case. We introduce a symplectic version of…
Laumon parahoric local models via quiver Grassmannians
Evgeny Feigin, Martina Lanini, Alexander Pütz
Local models of Shimura varieties in type A can be realized inside products of Grassmannians via certain linear algebraic conditions. Laumon suggested a generalization which can be…
Desingularizations of Quiver Grassmannians for the Equioriented Cycle Quiver
Alexander Pütz, Markus Reineke
We construct torus equivariant desingularizations of quiver Grassmannians for arbitrary nilpotent representations of an equioriented cycle quiver. We apply this to the computation…
Generalized juggling patterns, quiver Grassmannians and affine flag varieties
Evgeny Feigin, Martina Lanini, Alexander Pütz
The goal of this paper is to clarify the connection between certain structures from the theory of totally nonnegative Grassmannians, quiver Grassmannians for cyclic quivers and the…
GKM-Theory for Torus Actions on Cyclic Quiver Grassmannians
Martina Lanini, Alexander Pütz
We define and investigate algebraic torus actions on quiver Grassmannians for nilpotent representations of the equioriented cycle. Examples of such varieties are type flag…
Degenerate Affine Flag Varieties and Quiver Grassmannians
Alexander Pütz
We study finite dimensional approximations to degenerate versions of affine flag varieties using quiver Grassmannians for cyclic quivers. We prove that they admit cellular decompos…
