Abstract: In a recent preprint, in collaboration with Evgeny Feigin and
markus Reineke, we noticed that the degenerate flag varieties
introduced and studied by Feigin are indeed quiver Grassmannians, i.e.
varieties of subrepresentations of a given quiver representation M of
fixed dimension vector. In this talk we illustrate how this simple
observation helps in the study the geometry of degenerate flag
