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…

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…
