內(nèi)容介紹：This talk consists of two parts. The first one aims to improve existing regularity results for parabolic stochastic partial differential equations (SPDEs) with dissiptive nonlinearity. The second part is devoted to strong convergence analysis of a linear implicit time-stepping scheme for the finite element approximation of SPDEs with dissiptive nonlinearity. Strong convergence rates for the fully discrete scheme are successfully recovered both in space and in time.
