On Stabilizers of G-atoms of Representation-tame Categories

摘要

Given a locally bounded representation-tame k-category R over an algebraically closed field k and a torsionfree group G of k-linear automorphims of R the stabilizers of infinite G-atoms over R are described (Theorem 2.1). Representation embeddings of the module category over n-flowers induced by indecomposable locally finite dimensional modules are studied (Theorem 2.3).
