摘要: 在随机分布空间(S)-1上求解广义Wick-型随机迁移方程,并讨论解的性质。首先通过和式型泛函分离变量法,把求解方程约化为线性二阶随机常微分方程(SODE);然后再对方程SODE依次取两次积分又转化为随机维他里方程,从而获得了一类用级数表示的显式解,并论证此类解是存在的、唯一的和连续的。

Abstract: In this paper,we mainly solve the generalized Wick-type stochastic transport equation in the stochastic distributions spaces (S)-1 and discuss properties of the solutions. By the sum-type functional separation of variables,the equation is reduced into a linear second-order stochastic ordinary differential equation(SODE),and then the SODE,integrated twice in order,converts to a stochastic Volterra equation,so that we obtain a class of explicit solutions in series and argue that the class of solutions are existent and unique and continuous.

Key words: functional separation of variable, stochastic transport equation, linear second-order stochastic ordinary differential equation, explicit solution
