Modified log-Sobolev inequality for a compact PJMP with degenerate jumps

Abstract

We study the modified log-Sobolev inequality for a class of pure jump Markov processes that describe the interactions between brain neurons. In particular, we focus on a finite and compact process with degenerate jumps inspired by the model introduced by Galves and L\"ocherbach. As a result, we obtain concentration properties for empirical approximations of the process.
