Well-posedness and propagation of chaos for jump-type McKean-Vlasov SDEs with irregular coefficients

Zhen Wang, Jie Ren, Yu Miao

Abstract

In this paper, we study the existence and pathwise uniqueness of strong solutions for jump-type McKean-Vlasov SDEs with irregular coefficients but uniform linear growth assumption. Moreover, the propagation of chaos and the convergence rate for Euler's scheme of jump-type McKean-Vlasov SDEs are also obtained by taking advantage of Yamada-Watanabe's approximation approach and stopping time.

Key Result

Proposition 1.1
