  • On quasi-dual baer modules
    T. Amouzegar, Y. Talebi (pp. 78-86)
  • Abstract

    We introduce and study the notions of quasi-dual Baer modules, FI-T -non-cosingular modules and FI-K-modules. We show that a module M is a quasi-dual Baer and FI-K-module if and only if it is FI-lifting and FI-T -non-cosingular. A necessary condition for a direct sum of quasi-dual Baer modules to be quasi-dual Baer are obtained. A characterization is given of when a module is quasi-dual Baer, a necessary condition being that the endomorphism ring itself is a left quasi-Baer ring.

    Keywords

    quasi-dual Baer modules, quasi-Baer rings, FI-lifting modules, endomorphism rings.
