“…In [2] it was proved that the class of quotient divisible groups with locally free generalized characteristic coincides with the well-known class G of self-small groups of finite torsion and free rank, which was introduced by Glaz and Wickless in [6].…”

“…The ring of pseudorational numbers and modules over this ring were introduced by Fomin in [2] and Krylov in [12,13]. Later, in [3,4] Fomin applied such modules to the study of quotient divisible mixed groups and torsion free groups of finite rank.…”

“…Besides [2], modules over the ring of pseudorational numbers were treated in [14], where the injective modules were described, and in [13], where the ideals of the ring of pseudorational numbers were described and some questions about endomorphism rings and groups of homomorphisms for sp-groups were answered. This paper can be divided into three parts.…”

Abstract. Structure theorems are obtained for some classes of modules over the ring of pseudorational numbers and some classes of quotient divisible mixed groups.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
