我们研究受加性色噪声扰动的非线性随机Cahn-Hilliard方程,证明其解的几乎必然存在性与正则性;采用标准有限元方法进行空间近似,在概率任意接近1的集合上证明最优阶误差估计,同时证明了无已知收敛速率的强收敛性。
英文摘要
We study the nonlinear stochastic Cahn-Hilliard equation per- turbed by additive colored noise. We show almost sure existence and regularity of solutions. We introduce spatial approximation by a standard finite element method and prove error estimates of optimal order on sets of probability arbitrarily close to 1. We also prove strong convergence without known rate.
