Peter Junghanns is Professor Emeritus at the Mathematics Department of the Technical University of Chemnitz, Germany, where he got his habilitation in 1984. His field of specialization includes analysis and numerical methods for operator equations, in particular integral equations.
Giuseppe Mastroianni is emeritus professor of Numerical Analysis at the University of Basilicata (Italy) since 2013, where he had been full professor since 1987. In 1971 he graduated with honors in Mathematics at the University of Naples "Federico II", where he began his academic career. His scientific interests are focused on polynomial approximation, positive operators, mechanical quadrature and numerical treatment of integral equations. His research contributions have been published in numerous papers as well as the monographs "Interpolation processes. Basic theory and applications" (with G.V. Milovanovic) and "Elementi di teoria dell’approssimazione polinomiale" (with M.C. De Bonis and I. Notarangelo).
Incoronata Notarangelo is assistant professor in Numerical Analysis at the University of Turin (Italy) since 2019. After graduating with honors in Mathematics, she received a PhD in Mathematics from the University of Basilicata (in cooperation with the University of Szeged, Hungary) in 2010. Her scientific interests include polynomial approximation, quadrature rules and numerical methods for integral equations. Her research contributions appeared in various papers as well as the monograph "Elementi di teoria dell’approssimazione polinomiale" (with M.C. De Bonis and G. Mastroianni).
