Additivity of the algebraic entropy for locally finite groups with permutable finite subgroups
Anna Giordano Bruno, Flavio Salizzoni
The additivity with respect to exact sequences is notoriously a fundamental property of the algebraic entropy of group endomorphisms. It was proved for abelian groups by deeply exp…

The addition theorem for locally monotileable monoid actions
Dikran Dikranjan, Antongiulio Fornasiero, Anna Giordano Bruno +1
We prove an instance of the so-called Addition Theorem for the algebraic entropy of actions of cancellative right amenable monoids on discrete abelian groups by endomorphis…
