Abstract:

We aim to construct topological dynamical systems with ‘small’ symmetry group, 'large' extended symmetry group and ‘interesting’ entropy. In this talk we consider higher-dimensional binary shifts of number-theoretic origin. This includes the visible lattice points and the k-free integers in number fields, where we identify an interesting interplay between dynamical and number-theoretic notions. This is joint work with M. Baake, Á. Bustos, C. Huck, and M. Lemańczyk.

We look forward to welcoming you!

Sincerely,
S. Petersen
