Some Relations between Isologic and Varietal Perfect Groups

الملخص EN

In 1940, Hall introduced the notion of V-isologism, with respect to a given variety of groups ϑ.

In the present article, we study the concepts of V-perfect groups, V-subgroup, and V-quotient irreducible groups, with respect to a given variety of groups ϑ.

Also we prove and obtain some results.
