Self-repellent branching random walk
Anton Bovier, Lisa Hartung, Frank den Hollander
We consider a system of particles performing a discrete-time binary branching random walk with independent standard normal increments subject to a penalty $\b$ for every pair of pa…

From 1 to infinity: The log-correction for the maximum of variable-speed branching Brownian motion
Alexander Alban, Anton Bovier, Annabell Gros +1
We study the extremes of variable speed branching Brownian motion (BBM) where the time-dependent "speed functions", which describe the time-inhomogeneous variance, converge to the…
