Hello, The next Banach spaces webinar is on Friday February 5 at 9AM Central time. Please join us at https://unt.zoom.us/j/83807914306 Speaker: Sheng Zhang (Southwest Jiaotong University) Title: A metric characterizaion of Rolewicz's property ($\beta$) Abstract: In this talk we will give a new metric characterization of the class of Banach spaces admitting an equivalent norm of Rolewicz's property ($\beta$). Applications regarding the stability of property ($\beta$) under coarse Lipschitz embeddings and nonlinear quotients will be discussed. .
