在可分离的 Banach 空间 X 中,首先我们研究关于泊松随机测度 N(dsdz) 和由平稳泊松随机过程 p 生成的补偿泊松随机测度 N∼(dsdz) 的 X 值随机积分。当 p 的特征测度 ν 有限时,N(dsdz) 和 N∼(dsdz) 都具有有限变差。然后,关于泊松随机测度和补偿泊松随机测度的集值积分是可积分有界的。相对于补偿泊松随机测度的集值积分是右连续(在豪斯多夫度量下)集值鞅。
In a separable Banach space X, at first we study X-valued stochastic integrals with respect to the Poisson random measure N(dsdz) and the compensated Poisson random measure N∼(dsdz) generated by a stationary Poisson stochastic process p. When the characteristic measure ν of p is finite, both N(dsdz) and N∼(dsdz) are of finite variation a.s. Then the set-valued integrals with respect to the Poisson random measure and the compensated Poisson random measure are integrably bounded. The set-valued integral with respect to the compensated Poisson random measure is a right continuous (under Hausdorff metric) set-valued martingale.
