Birth-death processes are time-changed Feller's Brownian motions
Liping Li
A Feller's Brownian motion is a diffusion process on the half-line with general boundary behavior at the origin, described by four parameters. A birth-death process, on the other h…

Approximation of birth-death processes
Liping Li
The birth-death process is a special type of continuous-time Markov chain with index set . Its resolvent matrix can be fully characterized by a set of parameters $(γ,…
