Double jump in the maximum of two-type reducible branching Brownian motion
Heng Ma, Yan-Xia Ren
Consider a two-type reducible branching Brownian motion in which particles' diffusion coefficients and branching rates are influenced by their types. Here reducible means that type…

Stationary measures and the continuous-state branching process conditioned on extinction
Rongli Liu, Yan-Xia Ren, Ting Yang
We consider continuous-state branching processes (CB processes) which become extinct almost surely. First, we tackle the problem of describing the stationary measures on $(0,+\inft…

From 0 to 3: Intermediate phases between normal and anomalous spreading of two-type branching Brownian motion
Heng Ma, Yan-Xia Ren
The logarithmic correction for the order of the maximum of a two-type reducible branching Brownian motion on the real line exhibits a double jump when the parameters (the ratio of…
