Entropy Estimate for Degenerate SDEs with Applications to Nonlinear Kinetic Fokker-Planck Equations
Zhongmin Qian, Panpan Ren, Feng-Yu Wang
The relative entropy for two different degenerate diffusion processes is estimated by using the Wasserstein distance of initial distributions and the difference between coefficient…
Singular Degenerate SDEs: Well-Posedness and Exponential Ergodicity
Panpan Ren, Martin Grothaus, Feng-Yu Wang
The well-posedness and exponential ergodicity are proved for stochastic Hamiltonian systems containing a singular drift term which is locally integrable in the component with noise…
Probability Distance Estimates Between Diffusion Processes and Applications to Singular McKean-Vlasov SDEs
Xing Huang, Panpan Ren, Feng-Yu Wang
The -Wasserstein distance and the probability distance induced by a concave function , are estimated between different diffusion proc…
Bi-Coupling Method and Applications
Panpan Ren, Feng-Yu Wang
By developing a new technique called the bi-coupling argument, we estimate the relative entropy between different diffusion processes in terms of the distances of initial distribut…
