Formal matrices and their determinantsIn the present paper, we study formal matrix rings over
a given ring and determinants
E-groups and E-rings(R+) is an isomorphism. Additive groups of E-rings are called E-groups. In other words, an Abelian group
A is an E
Around the Baer-Kaplansky theoremUsing examples of modules and
a number of familiar Abelian groups, we demonstrate the Kaplansky
Modules over discrete valuation domains. IIIThis review paper is
a continuation of two previous review papers devoted to properties of modules
Rings over which all modules are I0-modules. IIAll right R-modules are I0-modules if and only if either R is
a right SV-ring or R/I(2) (R
