| Abstract: | The role of multiplication of group varieties is well known [2], as well as the role of wreath products in such a construction [1]. In the present paper the idea of exploiting wreath products is used for defining a multiplication for semigroup varieties which differs from the operations given in [3]. In section 5 we also consider some elementary properties of the defined multiplication. Some results of the paper were announced in [9]. |
