Interpolation and approximation

Possibility of approximation, analytic functions Possibility of approximation, continued Interpolation and lemniscates Degree of convergence of polynomials. Overconvergence Best Approximation by polynomials Orthogonality and least squares Interpolation by polynomials Interpolation by rational functions Approximation by rational functions Interpolation and functions analytic in the unit circle Approximation with auxiliary conditions and to non-analytic functions Existence and uniqueness of rational functions of best approximation Appendix Bibliography Index.
