Global Analysis of a Discrete Nonlocal and Nonautonomous Fragmentation Dynamics Occurring in a Moving Process

We use a double approximation technique to show existence result for a nonlocal and nonautonomousfragmentation dynamics occurring in a moving process. We consider the case wheresizes of clusters are discrete and fragmentation rate is time, position, and size dependent. Oursystem involving transport and nonautonomous fragmentation processes, where in addition, newparticles are spatially randomly distributed according to some probabilistic law, is investigated bymeans of forward propagators associated with evolution semigroup theory and perturbation theory. The full generator is considered as a perturbation of the pure nonautonomous fragmentationoperator. We can therefore make use of the truncation technique (McLaughlin et al., 1997), the resolvent approximation(Yosida, 1980), Duhamel formula (John, 1982), and Dyson-Phillips series (Phillips, 1953) to establish the existence of a solution for a discrete nonlocal and nonautonomous fragmentation process in a moving medium, hereby,bringing a contribution that may lead to the proof of uniqueness of strong solutions to this type oftransport and nonautonomous fragmentation problem which remains unsolved
