Dear all,

This is a reminder for the: STAR Online Seminars.

The seminar will be held Friday 23. October from 11:00-12:00 . You will recieve the link for the Zoom room by registering for the seminar with the link provided at the end of this mail. The lecture will last for 45 minutes + questions.

This week's speaker is Samy Tindel - University of Perdue, Indiana, with the seminar: A coupling between Sinai’s random walk and Brox diffusion

Abstract: Sinai’s random walk is a standard model of 1-dimensional random walk in random environment. Brox diffusion is its continuous counterpart, that is a Brownian diffusion in a Brownian environment. The convergence in law of a properly rescaled version of Sinai’s walk to Brox diffusion has been established 20 years ago. In this talk, I will explain a strategy which yields the convergence of Sinai’s walk to Brox diffusion thanks to an explicit coupling. This method, based on rough paths techniques, opens the way to rates of convergence in this demanding context. Notice that I’ll try to give a maximum of background about the objects I’m manipulating, and will keep technical considerations to a minimum.

After the end of the seminar, you are invited to bring a cup of coffee/tea and have a chat in our Coffee in the Stars here you will have the chance to talk and interact with the other persons that attended the seminar, and have a digital "coffee break".

We are looking forward to see you, online!
