A generalized discontinuous Hamilton Monte Carlo for transdimensional sampling
Lei Li, Xiangxian Luo, Yinchen Luo
In this paper, we propose a discontinuous Hamilton Monte Carlo (DHMC) to sample from dimensional varying distributions, and particularly the grand canonical ensemble. The DHMC was…

Equilibrium-diffusion limit of the radiation model
Lei Li
We justify rigorously the equilibrium-diffusion limit of the model consists of a radiative transfer satisfied by the specific intensity of radiation coupled to a diffusion equation…
