带移民的非临界分枝相依空间运动超过程
IMMIGRATION SUPERPROCESSES WITH DEPENDENT SPATIAL MOTION AND NON-CRITICAL BRANCHING
【摘要】 通过对一列带正跳跃的超过程取极限,本文构造了带移民的相依空间运动超过程.在此基础上,利用 Dawson型的Girsanov变换得到了相应的非临界分枝,此变换同时给出依赖于整体状态的空间漂移.
【Abstract】 A class of immigration superprocess with dependent spatial motion is constructed by a passage to the limit from a sequence of superprocesses with positive jumps. A non-critical branching is then obtained by using a Girsanov transform of Dawson’s type, which also gives a state-dependent spatial drift.
