Title: Resonance varieties

Abstract: I will discuss the Koszul modules introduced by Papadima and Suciu and their relation to Resonance Varieties and Alexander type invariants of finitely generated groups. In special case related to representations S_g(C^2) of SL_2 we get nilpotent modules whose nilpotency degree is related to Green conjecture for canonical curves of genus g. The talk is based on forthcoming work joint with Aprodu, Farkas, Papadima and Raicu.
