摘要: We investigate a class of Hilbert space valued martingale-valued measures whose covariance structure is determined by trace positive operator measure. The paradigm example the martingale part Levy process. develop both weak and strong stochastic integration with respect to such measures. As an application, we convolution C0-semigroup process associated Ornstein-Uhlenbeck give in¯nite dimensional generalisation concept self-decomposability conditions for random variables this type be embedded into stationary
