In this paper, we introduce the concept of modules with the properties (RE) and (SRE), and we provide various properties of these modules. In particular,we prove that a semisimple module M is Rad-supplementing if and only if M has the property (SRE). Moreover, we show that a ring R is a left V-ring if and only if every left R-module with the property (RE) is injective. Finally, we characterize the rings whose modules have the properties (RE) and (SRE). 2018-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/188354 Characterization of regular convolutions Sagi S.

We give a lower bound on multiplicative orders of certain elements in defined by Conway towers of finite fields of characteristic 2 and also formulate a condition under that these elements are primitive. 2018-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/188352 Weak equivalence of representations of Kleinian 4-group Plakosh, A. We give a classification of representations of the Kleinian 4-group up to weak equivalence. 2018-01-01T00:00:00Z
