Title: Etale groupoids, hyperbolic dynamics, and dimension

Abstract: We will discuss etale groupoids associated with hyperbolic dynamical systems, their structure, and applications to group theory and operator algebras. In particular, we will give a simple proof of finitness of their tower dimension (as defined by Kerr) and asymptotic dimension (as defined by Guentner, Willet, and Yu).
