It is assumed that the system is under a continual influence of independent stochastic impulses. In a short memory approximation the expression of the stochastic process is found. An application of the model proposed to capital market processes is examined. The approach allows form a stochastic differential for processes concerned. The analog of the Black-Scholes equation for assets dealt on a market with the memory is expressed.10 pagesProbabilityOptimization and ControlComputational Finance60-00;60G35text
