Conforming Finite Element Methods
IN Chapter 2 WE dealt with the abstract variational problems and some examples. In all our examples the function-space V is infinite dimensional. Our aim is to approximate V by means of finite dimensional subspaces Vh. and study the problem in V.. Solving the variational problem in V. will correspond to solving some system of linear equations. In this Chapter we will study an error estimate, the construction of Vh, and examples of finite elements.
