On Mild Contours in Ray Categories

  • Klaus BongartzEmail author


We generalize and refine the structure and disjointness theorems for non-deep contours obtained in the fundamental article ‘Multiplicative bases and representation-finite algebras’. In particular we show that these contours do not occur in minimal representation-infinite algebras.
