| Abstract: | The authors consider the limit circle of the following second order delay differential equations(r(t)x'(t) )'+ a(t)x(t) f(t,x))),...x(hn(t)))=0.(A)By using Liapunov function and weigh funtion,they obtain the sufficient conditions which guarantee all the solutions of(A)that belong to the limit circle. |
| Keywords: | two-order delay differential equations solution limit circle |
