| Abstract: |
| In this paper, we study a class of stochastic fractional-order age-dependent population dynamic system. By using fixed point theorem, stochastic analysis and semigroup of operators theory, the main conclusion of the existence and uniqueness of mild solution to stochastic fractional-order age-dependent population equations are obtained. This paper is a generalization of the stochastic integer order population system. |
| Key words: existence uniqueness stochastic fractional-order population system mild solution |
