Abstract

A lower solution (t) and upper solution (t) technique is used for second order boundary value problem if the function f (t, u, u1 ) involved satisfies | | | Such function must also satisfy Nagumo condition. It was observed that unlike in first order ordinary differential equations (ODE) there is ordering in the lower and upper solutions of second order ODE.
