Percolation Today is an online seminar aiming to promote the exchange of exciting new ideas on both Bernoulli and dependent percolation processes, at a level appropriate for specialists in the area. We hope to be a focal point to foster new connections and collaborations between the global community of percolation lovers.
You are warmly invited to sign up to our mailing list and attend to our seminars via Zoom.
The density conjecture for activated random walk
Speakers: Tobias Johnson and Matthew Junge
Date: February 3rd, 16:00 CET
Abstract: We solved the longstanding density conjecture for activated random walk by proving that several variants have the same critical value. The proof used a correspondence with a novel 2+1 dimensional oriented percolation process for which there is still much to unravel. Joint with Chris Hoffman.
