We describe an uncountable family of compact group automorphisms with entropy log2. Each member of the family has a distinct dynamical zeta function, and the members are parametrised by a probability space. A positive proportion of the members have p...

S-integer dynamical systems: periodic points (1997)
Journal Article
Chothi, V., Everest, G., & Ward, T. (1997). S-integer dynamical systems: periodic points. Journal für die reine und angewandte Mathematik, 1997(489), 99-132. https://doi.org/10.1515/crll.1997.489.99

We associate via duality a dynamical system to each pair (R_S,x), where R_S is the ring of S-integers in an A-field k, and x is an element of R_S\{0}. These dynamical systems include the circle doubling map, certain solenoidal and toral endomorphisms... Read More about S-integer dynamical systems: periodic points.
