Abstract

Cotilting modules and bimodules over arbitrary associative rings are studied. On the one hand we find a connection between reflexive modules with respect to a cotilting (bi)module U and a notion of U-torsionless linear compactness. On the other hand we provide concrete examples of cotilting bimodules over linearly compact noetherian serial rings.
