Abstract

In this paper, the Babuška's theory of Lagrange multipliers is extendedto higher order elliptic Dirichlet problems. The resulting variationalformulation provides an efficient numerical squeme in meshless methods forthe approximation of elliptic problems with essential boundary conditions.
