 The following stype equations are considered:The existence and uniqueness of solution for the equation belonging to space SI are discussed (in Theorem 1) and the Stype solution for Itypeaccompaniedequation has been obtained in space SI. Under certain conditions, a sample solution for 1dimensional case can be obtained by the same method as for ordinary differential equation.If the coefficients g(t,x) of the equation satisfy the following conditionthen the equation is called narrowsense equation.

The following stype equations are considered:The existence and uniqueness of solution for the equation belonging to space SI are discussed (in Theorem 1) and the Stype solution for Itypeaccompaniedequation has been obtained in space SI. Under certain conditions, a sample solution for 1dimensional case can be obtained by the same method as for ordinary differential equation.If the coefficients g(t,x) of the equation satisfy the following conditionthen the equation is called narrowsense equation. Such a kind of equations are both Stype and I type ones and their sample solutions can be found in a conventional way. When dm = 1 and G(t,x) =b(t)G(x), then it is shown that (in Corollary 2), under certain conditions, the equation can be converted into a narrow sense one. It has also been found that the sample solution for Stypelinear equation obtained in the conventional way is also the solution expressed in Stype integrals for I type accompanied e quation.  本文讨论S型方程解在空间SI中的存在与唯一性问题,证明S型方程具有按常规方式确定其样本解的特性。此外,讨论S型方程转化成自伴方程(狭义方程)问题。最后,作为特例,给出互伴线性方程解在S积分意义下的表示。  We prove the existence of sample soultions for stochastic Cauchy problems. By means of a known result about measurable selections of multivated maps, a existence theory is obtained, and then we discuss the existence of sample maximal and minimal soultions of first order stochastic periodic boundary value problem.  利用关于多值映射可测选择的结果，得到了一个随机柯西问题样本解的存在性定理。并且讨论了一阶周期边值问题的样本最大、最小解的存在性。  n this paper,we consider the sample solution of stochastic Cauchy problem in Abstract space,and gain two results.Theorem 1 gives the condition of existance, Theorem 2 gives the condition of uniqueness.  本文讨论抽象空间中随机Ｃａｕｃｈｙ问题的样本解，得到了两个主要结果，定理１给出了解的存在性条件；定理２给出了解的唯一性条件。   << 更多相关文摘
