Matrix Liberation Process I: Large Deviation Upper Bound and Almost Sure Convergence

  • Yoshimichi UedaEmail author


We introduce the concept of matrix liberation process, a random matrix counterpart of the liberation process in free probability, and prove a large deviation upper bound for its empirical distribution and several properties on its rate function. As a simple consequence, we obtain the almost sure convergence of the empirical distribution of the matrix liberation process to that of the corresponding liberation process as continuous processes in the large N limit.
