On stability of traveling wave solutions for integro-differential equations related to branching Markov processes

The aim of this paper is to prove stability of traveling waves for integro-differential equations connected with branching Markov processes. In other words, the limiting law of the left-most particle of a (time-continuous) branching Markov process with a L'{e}vy non-branching part is demonstrated. The key idea is to approximate the branching Markov process by a branching random walk and apply the result of A"{i}d'{e}kon [1] on the limiting law of the latter one.
