The order of Lebesgue constant of Lagrange interpolation on several intervals
A. L. Lukashov, J. Szabados
We consider Lagrange interpolation on the set of finitely many intervals. This problem is closely related to the least deviating polynomial from zero on such sets. We will obtain l…

A family of nonlinear difference equations: existence, uniqueness, and asymptotic behavior of positive solutions
Saud M. Alsulami, Paul Nevai, József Szabados +1
We study solutions of nonhomogeneous nonlinear second order difference equations of the type $\ell_n = x_n ( σ_{n,1} x_{n+1} + σ_{n,0} x_n + σ_{n,-1} x_{…

Discrete Linear Interpolatory Operators
J. Szabados
This is a survey on discrete linear operators which, besides approximating in Jackson or near-best order, possess some interpolatory property at some nodes. Such operators can be u…
