An improved uniqueness result for a system of stochastic differential equations related to the stochastic wave equation
C. Mueller, E. Neuman, M. Salins +1
We improve on the strong uniqueness results of [GLM+17], which deal with the following system of SDE. \begin{align*} dX_t&=Y_tdt \\ dY_t&=|X_{t}|^αdB_t \end{align*} and $X_0=x_0,Y_…

On the Maximal Displacement of Near-critical Branching Random Walks
Eyal Neuman, Xinghua Zheng
We consider a branching random walk on started by particles at the origin, where each particle disperses according to a mean-zero random walk with bounded support…
