Wave propagation for 1-dimensional reaction-diffusion equations with nonzero random drift
Dihang Guan, Hui He, Wenqing Hu +1
We consider the wave propagation for a reaction-diffusion equation on the real line, with a random drift and Fisher-Kolmogorov-Petrovskii-Piscounov (FKPP) type nonlinear reaction.…

Brownian continuum random tree conditioned to be large
Romain Abraham, Jean-Franç Ois Delmas, Hui He
We consider a Feller diffusion (Zs, s 0) (with diffusion coefficient $\sqrt$ 2 and drift R) that we condition on {Zt = at}, where at is a deterministic functio…

Large deviations for the maximum of a reducible two-type branching Brownian motion
Hui He
We consider a two-type reducible branching Brownian motion, defined as a particle system on the real line in which particles of two types move according to independent Brownian mot…
