Winter School JTP: Skew-gentle algebras and surface orbifolds, Claire Amiot

In the 80’s, Reiten and Riedtmann introduced the notion of skew-group algebra attached to an algebra with the action of a group by automorphisms. They studied in particular its representation theory. Skew-gentle algebras were introduced by Geiss and de la Pen ̃a in the 90’s as certain skew-group algebras of gentle algebras. The aim of this talk is to show how the geometric model of the derived category of gentle algebras developed by Opper, Plamondon and Schroll can be adapted to skew-group algebras.
