Special Year Learning Seminar

Algebraic Aspects of Normality and Determinism.

In 1976, Gérard Rauzy proved a characterization of deterministic numbers: y is deterministic iff for any normal number x, x+y is also normal. During my lecture I will discuss  how normal and deterministic numbers behave under arithmetic operations. I will conclude by posing a number of open problems. Based on joint work with Vitaly Bergelson.
