Filtered modules and A-infinity structures.

Abstract:

Let M be a module over a finite dimensional algebra A. In representation theory one is often interested in the category of modules filtered by the direct summands of M, e.g. for a quasi-hereditary algebra in the category of modules having a filtration by standard modules. This (first) talk presents the result of Keller and Lefèvre-Hasegawa that the algebra E=Ext
