Volterra积分微分方程的稳定性

ON THE STABILITY OF VOLTERRAo INTEGRO-DIFFERENTIAL EQUATIONS

考虑Ｖｏｌｔｅｒｒａ积分微分方程

n the present paper we consider Volterra integro-differential equations dx A(t)x+JoK (t,s)x (s)ds (l )where A(t) and K (t,s) are real--Valued functions Continuous for 0≤<∞ and 0≤s<t<∞,respectively.Some mew stability theorems for equations (1)are obtained,which improve some of results of the papers[3] and [4].
