McKean-Vlasov SDEs with Local Distributional Interactions: Well-Posedness and Entropy-Cost Estimates

Xing Huang, Panpan Ren, Feng-Yu Wang

We study McKean-Vlasov SDEs with interaction kernels in $\tt W^{-\dd,k},$ the local negative Sobolev space on with indexes $\dd \in [0,\infty)$ and We der…

Entropy-Cost Inequalities for McKean-Vlasov SDEs with Singular Interactions

Xing Huang, Panpan Ren, Feng-Yu Wang

For a class of McKean-Vlasov stochastic differential equations with singular interactions, which include the Coulomb/Riesz/Biot-Savart kernels as typical examples (Examples 2.1 and…

Extrinsic derivatives for SDEs and SPDEs with distribution dependent noise

Xiaochen Ma, Panpan Ren

The Bismut formula is a crucial tool characterizing regularities of stochastic systems, and has been extensively studied for various models. However it is not yet available for SDE…

Non-asymptotic convergence bounds of modified EM schemes for non-dissipative SDEs

Jianhai Bao, Jiaqing Hao, Panpan Ren

In this paper, we address the issue on non-asymptotic convergence bounds of Euler-type schemes associated with non-dissipative SDEs. On the one hand, for non-degenerate SDEs with s…

Log-Sobolev Inequalities and Exponential Ergodicity for Non-degenerate and Degenerate McKean-Vlasov SDEs

Xing Huang, Eva Kopfer, Panpan Ren

The exponential ergodicity of partially dissipative McKean-Vlasov SDEs in the \(L^1\)-Wasserstein distance has been extensively studied using asymptotic reflection coupling. Howeve…

Exponential Ergodicity in Relative Entropy and -Wasserstein Distance for non-equilibrium partially dissipative Kinetic SDEs

Xing Huang, Eva Kopfer, Pierre Monmarché +1

In this paper, we derive exponential ergodicity in relative entropy for general kinetic SDEs under a partially dissipative condition. It covers non-equilibrium situations where the…
