Methodologies and Application


Over the years, various types of differential equations have been employed to describe a myriad of processes driven by the respective forms of indeterminacy. This paper presents and examines uncertain stochastic differential equations and their important characteristics. An uncertain stochastic differential equation is a differential equation driven by both a Brownian motion and a canonical Liu process. Moreover, an uncertain stochastic differential equation with jumps is a differential equation driven by a Brownian motion, a canonical Liu process and an uncertain random renewal process. Based on an uncertain stochastic differential equation with jumps, this study suggests a stock model with jumps for Itô–Liu financial markets. Generalised stock models for Itô–Liu financial markets are introduced as well.
