p-adic entropy and a p-adic Fuglede-Kadison determinant
C. Deninger
Using periodic points we study a notion of entropy with values in the p-adic numbers. This is done for actions of countable discrete residually finite groups . For suitable $Γ=…

Expansive algebraic actions of discrete residually finite amenable groups and their entropy
Christopher Deninger, Klaus Schmidt
We prove an entropy formula for certain expansive actions of a countable discrete residually finite group by automorphisms of compact abelian groups in terms of Fuglede-Kadison…
