| 摘 要： | In this paper,we consider the oscillation of first order differential equation with several delays of the from x‘(t) ∑i=1 n PiX(t-ri)=0 (0.1) Where Pi,ri,(i=1,2,…,n) are positive constants. Our aim is to give a necessary and sufficient condition for all sollution of (0.1) to be oscillation, Which answers an open problem by B.G Zhang in 1]. |
