On the well posed solutions for nonlinear second order neutral difference equations
Marek Galewski, Ewa Schmeidel
In this work we investigate the existence of solutions, their uniqueness and finally dependence on parameters for solutions of second order neutral nonlinear difference equations.…

On the existence of bounded solutions for nonlinear second order neutral difference equations
Marek Galewski, Magdalena Nockowska Rosiak, Robert Jankowski +1
\noindent Using the techniques connected with the measure of noncompactness we investigate the neutral difference equation of the following form \begin{equation*} Δ\left(r_{n}\left…
