Second-order McKean-Vlasov stochastic evolution equation driven by Poisson jumps: existence, uniqueness and averaging principle

In the paper, a class of second-order McKean-Vlasov stochastic evolution equation driven by Poisson jumps with non-Lipschitz conditions is considered. The existence and uniqueness of the mild solution is established by means of the Carath eodory approximation technique. Furthermore, an averaging principle is obtained between the solution of the second-order McKean-Vlasov stochastic evolution equation and that of the simplified equation in mean square sense.
