Stability and instability of steady states for a branching random walk
Yaqin Feng, Stanislav Molchanov, Elena Yarovaya
We consider the time evolution of a lattice branching random walk with local perturbations. Under certain conditions, we prove the Carleman type estimation for the moments of a par…

Structure of the particle population for a branching random walk with a critical reproduction law
Daria Balashova, Stanislav Molchanov, Elena Yarovaya
We consider a continuous-time symmetric branching random walk on the -dimensional lattice, , and assume that at the initial moment there is one particle at every lattice…
