Directoids and directed groups
Algebra Universalis, 1995\textit{J. Ježek} and \textit{R. Quackenbush} [ibid. 27, No. 1, 49-69 (1990; Zbl 0699.08002)] have introduced directoids as groupoids corresponding exactly to up-directed posets (viz \(a \leq b\) iff \(ab = b\)). In this paper, this concept is further investigated, both in its own and in combination with an abelian group structure.

ON DIRECT PRODUCTS OF ABELIAN GROUPS
Mathematics of the USSR-Sbornik, 1983In this paper the author introduces a new notion — that of generalized slender abelian groups. The class of such groups is investigated and the role of this class in the study of direct products of arbitrary abelian groups is exhibited. Bibliography: 13 titles.
