Selforthogonal modules with finite injective dimension
SCIENCE IN CHINA (Series A), 2000, 43 (11): 1174~1181,-0001,():
The category consisting of finitely generated modules which are left orthogonal with a cotilting bimodule is shown to be functorially finite. The notion of left orthogonal dimension is introduced, and then a necessary and sufficient condition of selforthogonal modules having finite injective dimension and a characterization of cotilting modules are given.
