A global approximation method for second-kind nonlinear integral equations
Luisa Fermo, Anna Lucia Laguardia, Concetta Laurita +1
A global approximation method of Nyström type is explored for the numerical solution of a class of nonlinear integral equations of the second kind. The cases of smooth and weakly s…
On the error of best polynomial approximation of composite functions
Luisa Fermo, Concetta Laurita, Maria Grazia Russo
The purpose of the paper is to provide a characterization of the error of the best polynomial approximation of composite functions in weighted spaces. Such a characterization is es…
Filtered integration rules for finite Hilbert transforms
D. Occorsio, M. G. Russo, W. Themistoclakis
A product quadrature rule, based on the filtered de la Vallée Poussin polynomial approximation, is proposed for evaluating the finite Hilbert transform in [-1; 1]. Convergence resu…
