Title: Discrete diffusion on graphs and real hyperplane arrangementsSpeaker: David Wagner Affiliation: University of Waterloo Zoom: Please email Emma Watson To view the slides: Click here
In 2016, Duffy, Lidbetter, Messinger, and Nowakowski introduced the following variation of a chip-firing model on a graph. At time zero, there is an integer number of "chips" at each vertex. Time proceeds in discrete steps. At each step, each edge is examined (in parallel) -- one chip is moved from the greater end to the lesser end if the ends are not equal.
