Dear editor,rnThe stochastic singular system is also called the stochas-tic differential algebraic system,stochastic descriptor sys-tem,generalized stochastic system,and stochastic degen-erate system(e.g.,[1-4]).This type of system is found in numerous fields of application,which include fluid dynam-ics,the modeling of multi-body mechanisms,finance,input-output economics and the problem of protein folding.
