Abstract

 Let H be a connected finite dimensional wild hereditary path-algebra over an arbitrary field K and \(\) the Auslander-Reiten translation on H-mod, the category of finite dimensional H-modules. Let X be a finite dimensional H-module. We prove unexpected new results on the structure of the shifted modules \(\), for \(\), their minimal projective and injective resolutions, and the Auslander-Reiten components of the one-point extensions and coextensions of H by the modules \(\).
