摘要 利用广义伊藤公式证明了混杂随机时滞微分方程(SDDE)在局部Lipschitz和广义Khasminskii条件下存在唯一解,从而涵盖了一大类非线性混杂SDDE.最后给出实例说明了理论的可行性. In this paper,by using the generalized It formula,a generalized existence-and-uniqueness theorem for hybrid stochastic differential delay equations ( SDDEs ) is established under the local Lipschitz condition and the generalized Khasminskii-type conditions.The generalized Khasminskii-type theorem covers a wide class of nonlinear hybrid SDDEs.Finally,an example is given to illustrate the application of the theory.
