报告摘要:We establish sharp error estimates of the laws for Euler type discretization of some stochastic differential equations. In particular, we consider the discretization of Langevin diffusion with random batch approximation, and the equations with multiplicative noise. Our approach is to use the relative entropy, together with some integrability estimates of the derivatives of the logarithmic numerical density.
