具可积漂移的McKean-Vlasov方程的弱解与不变概率测度

Weak Solution and Invariant Probability Measure for McKean-Vlasov SDEs with Integrable Drifts

Xing Huang, Shen Wang, Fen-Fen Yang

摘要:

利用Wang的带幂的Harnack不等式和Banach不动点定理,研究了具有可积漂移的McKean-Vlasov方程的弱适定性.另外,利用解耦方法,证明了相对熵和不变概率测度的Sobolev估计等规律性。最后,利用Banach不动点定理,得到了具有可积漂移的对称McKean-Vlasov偏微分方程和随机哈密顿系统不变概率测度的存在唯一性.

英文摘要:

In this paper, by utilizing Wang's Harnack inequality with power and the Banach fixed point theorem, the weak well-posedness for McKean-Vlasov SDEs with integrable drift is investigated. In addition, using the decoupled method, some regularity such as relative entropy and Sobolev's estimate of invariant probability measure are proved. Finally, by Banach's fixed theorem, the existence and uniqueness of invariant probability measure for symmetric McKean-Vlasov SDEs and stochastic Hamiltonian system with integrable drifts are obtained.
