The Workshop, organized by the Department of Mathematics, Computer Sciences and Economics (DiMIE) of the University of Basilicata in collaboration with the University of Basilicata, the Department of Mathematics of the “Aldo Moro” University of Bari, the Department of Mathematics and Physics of the University of Salento and the “Mauro Picone” Institute for Applied Mathematics (IAC, CNR), is dedicated to Giuseppe Mastroianni on the occasion of his retirement as full professor at University of Basilicata (Potenza, Italy).

The aim of the Workshop is to bring together some of the most outstanding mathematicians that, in the last decades, also in collaboration with Giuseppe Mastroianni, have given significant contributions in the field of the Approximation Theory and in the development of its applications.

The scientific program consists of invited talks and in a poster session.

The topics are related to the main research interests of Giuseppe Mastroianni, including:

• Polynomial Approximation Theory

• Positive Operators

• Weighted Polynomial Inequalities

• Polynomial Interpolation Processes

• Rational Approximation

• Fourier Series

• Orthogonal Polynomials

• Quadrature Rules

• Numerical Methods for Integral Equations
