Feller branching diffusion
WebAug 1, 2024 · A diffusion process of that type was first studied by Feller [21], which is now referred to as the Feller branching diffusion. A general class of continuous-state branching processes were characterized in [29] as the weak limits of rescaled discrete-state branching processes.

WebFeller diffusion is a continuous branching process. The branching property tells us that for t > 0 fixed, when indexed by the initial condition, it is a subordinator (i. e. a positive–valued Lévy process), which is fact is a compound Poisson process.

Consider now, instead of a Feller branching diffusion, the same SDE with a logistic drift, namely dZx t= h θZx t −γ(Ztx) 2 i dt+2 p Zx t dW , Z x 0 = x, (1) where θ,γ > 0 are given parameters which will be fixed throughout the paper, and x > 0 is the initial population.
