Abstract:In this paper, we provide a construction of the so-called backbone decomposition for multitype supercritical superprocesses. While backbone decompositions are fairly well-known for both continuousstate branching processes and superprocesses in the one-type case, so far no such decompositions or even description of prolific genealogies have been given for the multitype cases.Here we focus on superprocesses, but by turning the movement off, we get the prolific backbone decomposition for multitype continuous-stat… Show more
