Abstract

The purpose of this research is to investigate solutions of boundary value problems of second-roder differential operator by  variational methods. Using variational formulation of the problems, existence of solutions of boundary value problems of second-order differential operator can be obtained.

Abstract

The purpose of this research is to investigate numerical solutions of boundary value problems of positive differential operator by finite-element methods.  The results showed that the finite-element methods can be implemented to obtained numerical solutions of boundary value problems of second-order positive differential operator.  Moreover, rate of convergence of Ritz finite-element with Lagrange quadratic interpolation be  in the the -norm and  in the energy norm.
