Abstract:

In this paper, we establish the weak convergence rate of density-dependent stochastic differential equations with bounded drift driven by $\alpha$-stable processes with $\alpha \in (1,2)$. The well-posedness of these equations has been previously obtained in Wu and Hao [Stochastic Process. Appl. 164 (2023), pp. 416–442]. We derive an explicit convergence rate in total variation for the Euler-Maruyama scheme, employing a technique rooted in Hao [McKean-Vlasov SDEs with singular drifts, Thesis (Ph.D.), Bielefeld: Universitatät Bielefeld; 2023].
