Branching Random Walks in a Random Killing Environment with a Single Reproduction Source
Vladimir Kutsenko, Stanislav Molchanov, Elena Yarovaya
We consider a continuous-time branching random walk on in a random non homogeneous environment. Particles can walk on the lattice points or disappear with random inten…

Branching Random Walks with One Particle Generation Center and Possible Absorption at Every Point
E. Filichkina, E. Yarovaya
We consider a new model of a branching random walk on a multidimensional lattice with continuous time and one source of particle reproduction and death, as well as an infinite numb…
