A product of varieties in relation to Baer invariants ⋆

The concept of the Baer invariant is useful in classifying groups into isologism classes. In this paper two sequences of varieties {rVn}n∈N0 and {lVn}n∈N0, are considered from a given variety V. The structure of Baer invariants of some groups with respect to these varieties, are determined for some specific V.
