Abstract:
We consider a continuous-time branching random walk with immigration on $\mathbf {Z}^d$ with branching sources located periodically. The asymptotic behavior of the mean number of particles at an arbitrary point is obtained for $t\to\infty$ in the supercritical and subcritical cases.
Key words and phrases:
branching random walk, periodic perturbation, the direct integral decomposition.
