Title: Identities Of Sum Of Two Pi-algebras In The Case Of Positive Characteristic
Abstract: We consider the following question posted by Beidar and Mikhalev in 1995 for an associative ring R = R1 + R2: is it true that if the subrings R1 and R2 satisfy polynomial identities, then R also satisfies a polynomial identity? Over a field of positive characteristic we establish new conditions on R1 and R2 that guarantee a positive answer to the question. We find upper and low bounds on the degrees of identities of R. © 2015 World Scientific Publishing Company.
