FYI ---------- Forwarded message --------- From: Salins, Mickey <[hidden email]> Date: Mon, Sep 14, 2020, 7:28 AM Subject: Probability and Statistics Seminar Announcement To: [hidden email] <[hidden email]>, [hidden email] <[hidden email]> Dear all,
This semester, the BU Probability and Statistics Seminar will highlight the research that our own graduate students and postdoctoral fellows are doing. The talks will be presented online on Zoom.
Our first talk of the semester will be this Thursday September 17, 2020 at 4:00pm and our speaker will be Zack Bezemek. All of the information is below.
Best, Mickey Salins
Speaker: Zack Bezemek (Boston University) Time and Date: September 17, 2020, 4:00pm Title: Multiscale Mean-Field Diffusions: Large Deviations for Joint Propagation of Chaos and Homogenization Abstract: Mean-field models describe a system of globally interacting particles where the effect of a single particle on the overall system becomes negligible as the number of particles increases. It is well known that in the limit as the number of particles tends to infinity, such a system undergoes the Propagation of Chaos: each particle's behavior becomes independent and identical to the others. Additionally, it has been shown that the limiting dynamics may have different and more complicated probabilistic structure than the prelimit system. The effect of introducing multiple scales to a single diffusion process is known to have a similar effect of creating different probabilistic structure in the limit as the scale separation increases. We work toward exploring how introducing multiple scales to a system of mean-field diffusions effects the limiting behavior as both the number of particles and scale separation tends to infinity. To do so, we study the large deviations principle of the empirical distribution of the particles' positions in this combined limit. All prerequisite knowledge beyond basic probability theory will be covered.
