Title: Entropy, partial hyperbolicity, and the work of Todd Fisher

Abstract: Todd Fisher’s work has had a significant impact on the world of smooth dynamics. From his body of work, two major themes emerge: entropy, a measure of chaos, and partial hyperbolicity, a property of a diffeomorphism general enough to encompass a broad range of dynamical features, but with enough structure to allow a deep understanding of the dynamics. I will discuss the mathematical universe in which Todd operated, viewed through the lens of these themes.
