Quasi-projective varieties are Grassmannians for fully exact subcategories of quiver representations
Alexander Pütz, Julia Sauter
Reineke and independent other authors proved that every projective variety arises as a quiver Grassmannian. We prove the claim in the title by restricting Reineke's isomorphism to…

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…

Totally nonnegative Grassmannians, Grassmann necklaces and quiver Grassmannians
Evgeny Feigin, Martina Lanini, Alexander Pütz
Postnikov constructed a cellular decomposition of the totally nonnegative Grassmannians. The poset of cells can be described (in particular) via Grassmann necklaces. We study certa…
