During the week of September 16 - 23, 2004, the Fifth International Conference on Functional Analysis and Approximation Theory was held at Acquafredda di Maratea (Potenza). Earlier meetings were held in 1989, 1992, 1996 and 2000 at the same place. The Conference was organized by the Center for Studies on Functional Analysis and Approximation Theory of the University of Basilicata (Potenza), directed by Prof. Giuseppe Mastroianni, with the collaboration of the National Research Group “Operator Theory, Semigroups and Applications to Evolution Equations and Approximation Problems”(PRIN – COFIN 2003-2005), directed by Prof. Francesco Altomare. Besides Francesco Altomare and Giuseppe Mastroianni, the organizing committee consisted also of Antonio Attalienti, Michele Campiti, Lorenzo D’Ambrosio, Sabrina Diomede, Donatella Occorsio and Maria Grazia Russo. The scientific committee consisted of Francesco Altomare, Antonio Attalienti, Michele Campiti, Romulus Cristescu, Giuseppe Mastroianni, Ioan Raşa, József Szabados and Peter Vertesi, The meeting was devoted to some significant aspects of contemporary mathematical research on Functional Analysis, Operator Theory and Approximation Theory including the applications of these fields in other areas such as partial differential equations, integral equations, numerical analysis and stochastic analysis. A special session was dedicated to Professor Giuseppe Mastroianni on the occasion of his 65th birthday, as a fair token of gratitude for his contribution to mathematics and to the organization of all the Maratea conferences (1989 – 2004). The Conference was attended by over 180 mathematicians coming from 25 countries. The scientific program consisted of 15 plenary lectures, 4 joint section talks and about 130 communications. Several thematic sessions were arranged. Among the main topics treated therein we mention: - Banach spaces, approximation in normed spaces. - Function spaces and approximation problems. - Linear operators on Banach spaces. Positive operators. Spectral theory. - Semigroups of operators, Feller semigroups and partial differential equations. Maximal regularity. Stochastic analysis. - Real functions and inequalities. Complex approximation. - Approximation by polynomials. Best approximation. - Approximation by positive operators. Rate of convergence. - Orthogonal polynomials. - Integral equations. - Interpolation and quadrature formulas. - Integral operators, integral transforms and Fourier integrals. - Wavelets and signal processing. - Numerical analysis and stability In this volume we collect some invited lectures together with a selection of the papers corresponding to the research talks, which have been carefully refereed. Our thanks go to the referees for their collaboration as well as for their accurate work.
