Abstract
Abstract The author recently proved that 1-cotilting modules are pure-injective; however, the problem of determining whether n-cotilting modules are pure-injective remained open. In this paper, necessary and sufficient conditions are given for the pure-injectivity of n-cotilting modules. 2000 Mathematics Subject Classification 16D90 (primary), 16D30 (secondary). © London Mathematical Society
