Resumen de Convergence analysis for least-squares finite element approximations of second-order two-point boundary value problems
In this paper, a C0 least-squares finite element method for second-order two-point boundary value problems is considered. The problem is recast as a first-order system.
Standard and improved optimal error estimates in maximum-norms are established.
Superconvergence estimates at interelement, Lobatto, and Gauss points are developed.
Numerical experiments are given to illustrate theoretical results.
