Minimal Self-Joinings of Substitutions Arising from IETs

Minimal Self-Joinings of Substitutions Arising from IETs

Kelly Yancey, University of Maryland
Fine Hall 601

In this talk we will discuss substitution systems that have the property of minimal self-joinings. Then we will focus our attention on self-similar interval exchange transformations and their associated substitutions. We will show that 3-IETs have MSJ. This is joint with Giovanni Forni.
