| Abstract: |
| In this article, we study stochastic differential equations (SDEs) with different drift and diffusion coefficients which are driven by fractional Brownian motions. By using the generalized sample solutions of SDEs, two comparison theorems are obtained. moreover, we give their applications and propose an asymptotic optimal strategy. |
