带奇异系数的随机(偏)微分方程∗
Stochastic (partial)differential equations with singular coefficients
摘要
Abstract
It is well known that a nice noise may actually improve the properties of differential equations. For instance,an ODE is ill-posed if the coefficient is merely Hölder continuous,but with a Gaussian noise the equation is well-posed if the drift is only locally integrable with power larger than dimension;and the noise may make singular distribution smooth.Recent progress on integrability conditions for the non-explosion and regularity estimates of the invariant probability measures for stochastic differential equations driven by Brownian motion is surveyed.References on the study for more general models are also introduced.关键词
