$W_{d}$ -convergence rate of EM schemes for invariant measures of supercritical stable SDEs

Peng Chen, Lihu Xu, Xiaolong Zhang +1

By establishing the regularity estimates for nonlocal Stein/Poisson equations under $γ$ -order Hölder and dissipative conditions on the coefficients, we derive the $W_{d}$ -conve…

Quantitative diffusion approximation for the Neutral $r$ -Alleles Wright-Fisher Model with Mutations

Peng Chen, Jie Xiong, Lihu Xu +1

We apply a Lindeberg principle under the Markov process setting to approximate the Wright-Fisher model with neutral $r$ -alleles using a diffusion process, deriving an error rate ba…
