Dynamics Seminar-Spectral Ergodic Theory IV
Thursday, 2/25/2021, 4:00pm - 11:59pm
Time: 11 am, Thursday, February 25
Speaker: Robbie Robinson
Place: Zoom(virtual)
Title: Spectral Ergodic Theory IV
Abstract: We will introduce ergodic actions of locally compact abelian groups (notable Z^d and R^d) and explain how to use spectral theory to define some of their ergodic properties. Then we begin the proof of the spectral theorem in that context. We will begin with graduate student presentations

Dynamics Seminar-Spectral Ergodic Theory III
Thursday, 2/18/2021, 4:00pm - 11:59pm
Time: 11 am, Thursday, February 18
Speaker: Robbie Robinson
Title: Spectral Ergodic Theory III
Abstract: Spectral measures will be defined for transformations. One version the spectral theorem will be stated. We will also introduce ergodic actions of locally compact abelian groups (notable Z^d and R^d) and explain how to extend spectral theory to such cases.
Dynamics Seminar-Spectral Ergodic Theory II
Thursday, 2/11/2021, 4:00pm - 11:59pm
Time: 11 am, Thursday, February 11 (2/11/2021 at 11)
Speaker: Robbie Robinson
Title: Spectral Ergodic Theory II
Abstract: Some examples of spectral properties include ergodicity, weak mixing, and mixing. There are also discrete spectrum, singular spectrum, Lebesgue spectrum and various types of mixed spectrum. And of course, there is spectral multiplicity. We first describe what these are for measure preserving transformations, then for flows, and finally for actions of Z^d and R^d.
Dynamics Seminar-Gibbs Measure (VII)
Thursday, 2/4/2021, 4:00pm - 11:59pm
Speaker: Lien-Yung (Nyima) Kao
Date and Time: Thursday February 4th, 11am
Title: Gibbs Measure (VII)
Abstract: We will discuss the proof of the uniqueness of the equilibrium states for Hölder continuous functions over subshifts of finite type.

Dynamics Seminar-Gibbs Measure (VI)
Thursday, 1/28/2021, 4:00pm - 11:59pm
Speaker: Lien-Yung (Nyima) Kao
Date and Time: Thursday January 28th, 11am
Title: Gibbs Measure (VI)
Abstract: We will continue our unfinished discussion on the properties of Gibbs measure including the variance principle and the uniqueness of equilibrium states. The discussion will based on Bowen's lecture notes on thermodynamic formalism.
