Описание: Abstract: I will explain how one can use constructible sheaves valued in enhanced triangulated categories (stable infinity-categories) living on graphs to describe triangulated categories appearing in representation theory. Examples include the derived categories of Ginzburg algebras associated with triangulated surfaces and derived categories of (graded) Brauer graph algebras. I will further survey how such constructible sheaves are related to categorified perverse sheaves (perverse schobers) on surfaces.
