| Abstract: | In this paper,we study the fourth order non-homogeneous differential equations x(4) + f1()+ f2() + f3(■) + f4(x) = p(t,x,■,,x),and obtain suffcient conditions,under which the solutions to the system tend to zero as t →∞. |
| Keywords: | non-homogeneous differential equations fourth order stability Lya-punov function |
