A new course on the interplay between abelian sandpiles (prototypical model of self-organized criticality) and tropical geometry (contemporary branch of mathematics) will start on October 28th: https://icms.bg/sandpiles-and-tropical-geometry-specialized-phd-course/ The meetings are planned to be from 16:00 to 19:00 (GMT+3) on most Tuesdays and Thursdays until the end of the year — with two hours of lectures followed by one hour of discussions/exercises. The first two meetings are scheduled for 28th and 30th of October, room 578 at IMI-BAS (the room may change in November) and Zoom (the link will remain the same): https://us06web.zoom.us/j/86556797224?pwd=g1gjtRHFenzbgJ9s29kOo1nZQVqcoR.1 The meetings will not be recorded; however, the notes will be made available at the website of the course.
