This volume contains the proceeding of the INDAM workshop entitled "Polynomial identites in algebras" held in Rome during September 2019. The purpose of the workshop was to present the current state of the art in the theory of PI-algebras. The review of the classical results in the last few years has pointed out new perspectives for the development of the theory. In particular, the contributions emphasize on the computational and combinatorial aspects of the theory, its connection with invariant theory, representation theory, growth problems. It is addresssed to researchers in the field.weiterlesen
