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…
