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…
