摘要:
本文证明了在UMD Banach空间X中,乘性噪声半线性抛物型随机微分方程的隐式欧拉格式具有最优路径wise Hölder收敛性。我们假设非线性项满足适当的(局部)Lipschitz条件。通过首先证明分裂格式的相应结果,得到了收敛结果。这些结果应用于一类由乘性时空白噪声驱动的二阶抛物型SPDEs。
英文摘要:
In this article we prove pathwise Holder convergence with optimal rates of the implicit Euler scheme for semi-linear parabolic stochastic differential equations with multiplicative noise, set in a UMD Banach space X. We assume the non-linearities to satisfy appropriate (local) Lipschitz conditions. The convergence results are obtained by first proving corresponding results for the splitting scheme. The results are applied to a class of second order parabolic SPDEs driven by multiplicative space-time white noise.
