Kusuoka-Stroock Formula on Configuration Space and Regularities of Local Times with Jumps
TL;DR: In this article, the authors extend the classical Ito stochastic integral to the case of measurable fields of Hilbert spaces and prove a Kusuoka-Stroock formula on configuration space, which is used to study the fractional regularities of local times with jumps in the sense of the Malliavin calculus.

Euler scheme for density dependent stochastic differential equations
TL;DR: In this paper, the existence and uniqueness of a class of density dependent SDEs with bounded measurable drift was proved for the case where the existence part is based on Euler's approximation for density dependent sDEs and the uniqueness part is due to the associated nonlinear Fokker-planck equation.
Journal ArticleDOI
Quasi-sure analysis of two-parameter stochastic differential equations
Jiagang Ren,Xicheng Zhang +1 more
TL;DR: In this paper, a Stroock-Varadhan type quasi-sure limit theorem for stochastic differential equations in the plane is proved for the case of continuous-time differential equations.
Journal ArticleDOI
Well-posedness of fully nonlinear and nonlocal critical parabolic equations
TL;DR: In this paper, the authors prove the existence of smooth solutions in Sobolev spaces to fully nonlinear and nonlocal parabolic equations with critical index, and transform the fully non-linear equation into a quasi-linear non-local parabolized equation.
Journal ArticleDOI
Variational Approximation for Fokker–Planck Equation on Riemannian Manifold
TL;DR: In this paper, a variational approximation for Fokker-Planck equation on Riemannian manifold M is constructed by the scheme of Jordan et al. in SIAM J Math Anal 29(1):1−17, 1998.
