具有奇异漂移和梯度噪声的随机发展方程的曲率和对易条件

Stochastic evolution equations with singular drift and gradient noise via curvature and commutation conditions

Jonas M. Tölle

摘要:

本文证明了$d$维环面上一类非线性随机发展方程解的存在唯一性,其中奇异$p$ -Laplace型或全变差流型漂移具有一般的次线性倍化非线性项,高斯梯度Stratonovich噪声具有无发散系数.在弱亏换位子界和曲率维数条件下,利用预解式和Dirichlet形式方法以及Itô-公式的近似,得到了随机变分不等式中的适定性结果.

英文摘要:

We prove existence and uniqueness of solutions to a nonlinear stochastic evolution equation on the $d$-dimensional torus with singular $p$-Laplace-type or total variation flow-type drift with general sublinear doubling nonlinearities and Gaussian gradient Stratonovich noise with divergence-free coefficients. Assuming a weak defective commutator bound and a curvature-dimension condition, the well-posedness result is obtained in a stochastic variational inequality setup by using resolvent and Dirichlet form methods and an approximative Itô-formula.
