We derive a cancellation theorem for degenerations of modules that says in particular, that projective or injective common direct summands can always be neglected. Combining the cancellation result with the existence of almost split sequences we characterize the orbit closure of a module living on p
Let G be a group in the class LHα of locally hierarchically decomposable groups and let R be a strongly G-graded algebra. We provide a characterization of the R-modules of type FP under the assumptions that R is coherent and of finite Ο± 1 global dimension.
