The authors consider the problem of the existence, with probability 1, of Green’s function of a stochastic m-point Cauchy problem for a higher-order parabolic equation with white noise perturbations taken with negative values only. Estimates are obtained in spaces of functions whose norm contains the mathematical expectation. 相似文献

Using the second Lyapunov–Krasovskii method, sufficient conditions are obtained for the asymptotic stochastic global stability, for the global stability, and mean-square stability of trivial solutions to systems of diffusion stochastic functional–differential equations with Markov switchings, and the theory is illustrated by two model problems. 相似文献

The small-parameter method and the notion of averaged system are used to analyze the asymptotic stability in the mean square of the original system of stochastic differential equations. The stability of a system with continuous perturbations is considered. It is proved that the small-parameter method can be applied to stochastic differential equations with discontinuous trajectories, i.e., that stochastic differential depends on the Poisson integral. 相似文献

Optimal linear filtering for systems of stochastic differential equations with poisson perturbations
The Kalman–Bucy filter that can be modeled by computer statistical design is constructed for stochastic dynamic systems with
Poisson perturbations. It is proved that a stationary filter coincides with the Wiener filter for the optimal mean-square
filtering of stationary sequences in the absence of Poisson perturbations. 相似文献
