报告摘要 | This talk is on strong approximations of stochastic wave equations (SWEs) with nonlinear damping. Unlike the standard case, the SWEs considered here have a nonlinear damping, which might grow polynomially. Based on a spatial discretization of the continuous problem, an exponential Euler type time-steeping scheme is proposed and the resulting approximation errors are analyzed in a strong sense. Explicit convergence rates are proved under certain regularity assumptions. | ||
