Abstract

The main focus of this paper is to explore how much similarity between two stochastic differential systems. Motivated by the conjugate theory of stochastic dynamic systems, we study the relationship between two systems by finding homeomorphic mappings KK. Particularly, we use the minimizer KK^* to measure the degree of similarity. Under appropriate assumptions, we give sufficient and necessary conditions for the existence of the minimizer KK^*. The former result can be regarded as a strong law of large numbers, while the latter is a stochastic maximum principle. Finally, we provide different examples of stochastic systems and an application to stochastic Hartman Grobman theorem. Thus, the results illustrate what is the similarity, extending the conjugacy in stochastic dynamical systems.
