Henk Bruin, Matching for generalized $\beta$-transformations

Abstract: This talk is about the parameter space of a family of shifted $\beta$-transformations $T$ in regard to the property of “matching”. This means that at some iterate $T^n(0) = T^n(1)$, and it has a bearingon the invariant density of $T$. The prevalence of matching is proved under specific number-theoretic conditions: the slope $\beta$ is a(specifically quadratic) Pisot number.

Iztok Banič, The (weak) full projection property for inverse limits with upper semicontinuous bonding functions

Abstract: we give new results about the full projection property and the weak full projection property for inverse limits with upper semicontinuous functions. This solves several problems stated by W. T. Ingram
