分支随机游动的算子方程

Operator Equations of Branching Random Walks

E. Yarovaya

摘要:

考虑到连续时间的超临界分支随机游动在一个多维晶格与有限数量的粒子产生源的相同强度都有和没有约束的变化跳跃的随机游动的过程。建立了粒子平均数演化算符的格林函数和本征值在源强度接近临界强度时的渐近性质。

英文摘要:

Consideration is given to the continuous-time supercritical branching random walk over a multidimensional lattice with a finite number of particle generation sources of the same intensity both with and without constraint on the variance of jumps of random walk underlying the process. Asymptotic behavior of the Green function and eigenvalue of the evolution operator of the mean number of particles under source intensity close to the critical one was established.
