DESCRIPTION:Title:  The diffusion analogue to a tree-valued Markov chain.\n
 \nAbstract. In '99\, David Aldous conjectured that a certain Markov chain 
 on the space of binary combinatorial trees should have a continuum analogu
 e\, which would be a continuum-tree-valued diffusion - a continuous stocha
 stic process on a space of tree-like metric spaces. This talk discusses wo
 rk by F-Pal-Rizzolo-Winkel that has verified this conjecture with a path-w
 ise construction of the diffusion. Our approach explores connections betwe
 en tree growth processes\, the Chinese restaurant process\, Galton-Watson 
 and Crump-Mode-Jaegers branching processes\, Wright-Fisher diffusions\, an
 d stable Lévy processes.\n\nZoom: https://mcgill.zoom.us/j/82167352773?pwd
