Einstein relation for biased random walk on Galton--Watson trees
Gerard Ben Arous, Yueyun Hu, Stefano Olla +1
We prove the Einstein relation, relating the velocity under a small perturbation to the diffusivity in equilibrium, for certain biased random walks on Galton--Watson trees. This pr…

The precise tail behavior of the total progeny of a killed branching random walk
Elie Aïdékon, Yueyun Hu, Olivier Zindy
Consider a branching random walk on the real line with a killing barrier at zero: starting from a nonnegative point, particles reproduce and move independently, but are killed when…
