| Research Abstract |
We gave a proof of the indecomposability for certain Heller lattices over integral group rings. Also, we investigated the Auslander-Reiten quiver of an integral group ring, and we showed that Auslander-Reiten components containing trivial source lattices belonging to a block of infinite representation type are of type A-infinity and trivial source lattices lie at the end of their components.
