Abstract: |
The higher order nonlinear functional differential equation, x(n)(t)+p(t)f(x(g(t)=r(t) is discussed by using Schauder's fixed point theorem, some necessary and sufficient coditions for existence of positive solution of the equation are established. |
Key words: functional differential equation positive solution fixed point theorem |
