Abstract
One of the first areas in which the basic variational concepts and methods are applied is the solution of large, important classes of linear boundary and eigenvalue problems. The results discussed in this chapter follow in part from the results on nonlinear boundary and eigenvalue problems which we shall discuss in Chap. 8; nonetheless we present proofs in this chapter which emphasise the simplicity and elementary character of the variational approach. We start with a variational proof of the spectral theorem for compact self-adjoint operators, followed by a general version of the projection theorem (for convex closed sets).
