Title: Lipschitz embeddings of random binary sequences
Abstract: Basu and Sly proved in 2014 the almost sure existence of Lipschitz embeddings between random binary sequences. This talk briefly introduces their ideas and methods and discusses possible applications in related problems.

Title: Basic concepts in ergodic theory and ergodic optimization
Abstract: Ergodic theory studies statistical properties of deterministic dynamical systems where statistical properties refer to properties expressed by the time averages of functions. Ergodic theorems connect ‘time average’ with ‘space average’, which leads to the study of invariant measures. The newly developed branch, ergodic optimization, focuses on the maximal time/space average and maximizing (invariant) measures.

Title: Ergodic optimization and Best Laminations on Hyperbolic surfaces
Abstract: After briefly reviewing fundamental notions on hyperbolic geometry such as geodesic laminations, we talk about the maximally stretched laminations for circle-valued map by Daskalopoulos-Uhlenbeck and how ergodic optimation might clarify their structure which have other applications to analysis and fibrations.
