摘要
The objective of this paper is to investigate the structure of a general subcritical branching measure-valued process X subject to the usual regularity conditions. We prove that, if the second moments of the total mass X(t)(E) are finite, then X is a superprocess and we give an explicit expression of the branching characteristics Q and l in terms of the continuous martingale component of the total mass X(t)(E) and the Levy measure (jumps compensator) of X.
