| Abstract: | Singular perturbation of three-point boundary value problem for third order nonlinear equation is studied by using of Volterra type integral operator and differential inequality techniques.The existence and uniqueness and asymptotic estimmation of the solutions are obtained.The use of these techniques to study for these kinds of third-order boundary value problems seems to be new. |
