# Dynamics Lunch: Ohad Feldheim (HUJI) "Finitely dependent proper colouring of Z"

12:00pm to 1:00pm

An M-dependent process X(n) on the integers, is a process for which every event concerning with X(-1),X(-2),... is independent from every event concerning with X(M),X(M+1),...

Such processes play an important role both as scaling limits of physical systems and as a tool in approximating other processes.

A question that has risen independently in several contexts is:

"is there an M dependent proper colouring of the integer lattice for some finite M?"
