n-COTILTING MODULES AND PURE-INJECTIVITY
Published online by Cambridge University Press: 24 August 2004
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.
