摘要: In this talk, we mainly consider the asymptotic behavior of a certain quasilinear PDE with smeared mild noise, which originally appears as the space-time scaling limit of a zero-range process in random environment on one dimensional discrete lattice. Using the approach of the paracontrolled calculus, we establish the convergence result of the quasilinear SPDE driven by a smeared mild noise and show the local-in-time solvability of the limit quasilinear SPDE with spatial white noise. This talk is based on a joint work with T. Funaki, M. Hoshino and S. Sethuraman.
