| Abstract: |
| In this paper, the existence and uniqueness and moment boundedness of solutions to stochastic functional difierential equations with inflnite delay are studied. By using the method of Lyapunov functions and the introduction of probability measures, a new condition which assures that the equations have a unique solution and at the same time the moment boundedness, the moment average in time boundedness of this solution is obtained. Relevant results about the Khasminskii-Mao theorems are generalized. |
