Linear degenerations of Schubert varieties
Giulia Iezzi
We define linear degenerations of Schubert varieties via a special class of quiver Grassmannians. To do so, we restrict our study to an appropriate subvariety in the variety of rep…

Quiver Grassmannians for the Bott-Samelson resolution of type A Schubert varieties
Giulia Iezzi
We realise the Bott-Samelson resolutions of type A Schubert varieties as quiver Grassmannians. In order to explicitly describe this isomorphism, we introduce the notion of a \texti…

Tropical Quiver Grassmannians
Giulia Iezzi, Victoria Schleis
We introduce quivers of valuated matroids and study their tropical parameter spaces. We define quiver Dressians, which parametrize containment of tropical linear spaces after tropi…
