Abstract
The algebras A a,b appeared in the study of the tensor products of verbally prime PI algebras. They are in-between the well known algebras M n (E) and \({M_{a,b}(E)\otimes E}\), see the definitions below. Here E is the Grassmann algebra. The main result of this note consists in showing that the algebras A a,b and M a+b (E) are not PI equivalent in characteristic p > 2.
