Otto Kerner (Düsseldorf). An introduction to wild hereditary algebras.

Abstract:
Let K be some field and Q a finite connected quiver without oriented cycles. The path-algebra KQ is wild hereditary if and only if Q is neither of Dynkin nor of Euclidean type. In the talk first results on morphisms in H-mod, where H is wild hereditary will be presented. If there is time, perpendicular categories of quasi simple regular rigid H-modules will be considered.
