Particle representations of superprocesses with dependent motions
Department or Administrative Unit
We establish Donnelly–Kurtz-type particle representations for a class of superprocesses with dependentspatial motions, and for a sequence of such superprocesses we prove convergence of the finite-dimensionaldistributions given convergence of the motion processes. As special cases, we construct a superprocesswith coalescing spatial motion (SCSM) and a superprocess with dependent spatial motion (SDSM),where the underlying motion processes are one-dimensional coalescing and dependent Brownian motions,respectively. Under suitable conditions on the functions governing the interactions, we show convergencein distribution inDP(R)[0,∞)of a sequence of SDSMs to an SCSM.
