algebraic entropy and topological entropy

Algebraic Entropy and Topological Entropy

Scope of the special session

The study of the topological entropy, started in 1965 with a paper by Adler, Konheim and McAndrew, continued up to now with frequent contributions of many mathematicians. On the other side, the algebraic entropy, introduced in the same paper, was studied only sporadically until some years ago, when it was deeply investigated in a paper by Dikranjan, Goldsmith, Salce and Zanardo in 2009. Since then, almost thirty papers have been published on the subject, of purely algebraic character, or in connection with the topological entropy and with the metric entropy appearing in the theory of dynamical systems.

This special session is aimed to check the state of the art of these themes and of their connections. Some mathematicians who gave important contributions to these theories come from Italy and Spain.
