Complete classification of two classes of two-dimensional PI-algebras over any basic field; [Полная классификация двух классов двумерных PI-алгебр над любым основным полем]
In the paper we give complete classification of two classes of two-dimensional PI-algebras over any basic field. The choice of these two classes is predicted by the polynomial identities of the classes: the identity of one of them is given by using the binary operation of the algebra another one inv...
