Títol: Identities in prime rings.
Resum: Given a ring, a generalized polynomial identity (GPI) is a polynomialidentity in which the coefficients can be taken from the ring. Primerings are a class of rings very well suited to manage problems related toidentities, as for example those coming from Herstein’s theory, which isthe study of nonassociative objects and structures arising from associa-tive rings. After a motivating introduction to prime rings, with someexamples from Herstein’s theory, I will show the usefulness of Martin-dale’s lemma, the key tool for solving GPIs in one variable in primerings, and I will explain a new promising approach to solve them basedon elementary algebraic geometry which avoids some shortcomings ofthe lemma, allowing to find the optimal solutions.
