Distribution Dependent Birth-Death Processes: ${\mathbb{W}}_p$-Estimate, Ergodicity and Propagation of Chaos

For a class of time inhomogenous distribution dependent birth-death processes, we derive the well-posedness, ${\mathbb{W}}_p$-estimate, exponential ergodicity, and uniform in time propagation of chaos. These extend the corresponding results derived for distribution dependent SDEs and mean field particle systems. As preparation, a criterion on the well-posedness of inhomogenous jump process is presented in the end of the paper, which should be interesting by itself.
