Approximation of Eigenvalues and EigenvectorsIn this chapter we deal with approximations of the eigenvalues and eigen-vectors of a matrix A ∈ ℂ. Two main classes of numerical methods exist to this purpose, . methods, which compute the . eigen-values of A (that is, those having maximum and minimum module), or . methods, which approximate the whole spectrum of A.

Orthogonal Polynomials in Approximation TheoryTrigonometric polynomials, as well as other orthogonal polynomials like Legendre’s and Chebyshev’s, are widely employed in approximation theory.

Two-Point Boundary Value ProblemsThis chapter is devoted to the analysis of approximation methods for two-point boundary value problems for differential equations of elliptic type. Finite differences, finite elements and spectral methods will be considered. A short account is also given on the extension to elliptic boundary value problems in two-dimensional regions.
