Abstract: |
In this article,the exponential stability in p-moment of a linear neutral stochastic differential equation with variable delays is discussed.By using the fixed point theory rather than the Lyapunov functions,we get a sufficient condition of exponential stability in p-moment theorem when coefficient functions of equations are not required to be fixed values.Since we get more general results.this article improves Luo Jiaowan's results.Finally,an example is provided to illustrate the efficiency of the obtained results. |
