It is a useful method in research of group theory to construct a new group by using known groups. Lower and upper approximation operators of rough sets are applied into group theory and so the notion of a rough group has been introduced. In this paper, we first point out that there are still some in

presented a formula for the Schur multiplier of a regular product of groups. In this paper, first, it is shown that the Baer-invariant of a nilpotent product of groups with respect to the variety of nilpotent groups has a homomorphic image and in finite case a subgroup of Haebich's type. Second, a f
Let S be a finite subset of a group G, |S| = n, and let g โ S โข S. Then g induces a partial function ฮป g : S โ S by ฮป g (s) = t if and only if st = g and ฮป g (s) is not defined if g โ sS. For every g โ S โข S, ฮป g is a one-to-one mapping. In this note we describe the groups which have a finite genera
