Weak order in averaging principle for two-time-scale stochastic partial differential equationsFeb 03 2018This work is devoted to averaging principle of a two-time-scale stochastic partial differential equation on a bounded interval $[0, l]$, where both the fast and slow components are directly perturbed by additive noises. Under some regular conditions on ... More
Strong convergence rate in averaging principle for stochastic hyperbolic-parabolic equations with two time-scalesNov 28 2016Dec 21 2017In this article, we investigate averaging principle for stochastic hyperbolic-parabolic equations with two time-scales, in which both the slow and fast components are perturbed by multiplicative noises. Particularly, we prove that the rate of strong convergence ... More
First order least squares method with weakly imposed boundary condition for convection dominated diffusion problemsSep 27 2013Oct 08 2014We present and analyze a first order least squares method for convection dominated diffusion problems, which provides robust L2 a priori error estimate for the scalar variable even if the given data f in L2 space. The novel theoretical approach is to ... More
