Eigenvalue problems for singular multi-point dynamic equations on time scales

Electronic Journal of Differential Equations, 2017
In this article, we study a singular multi-point dynamic eigenvalue problem on time scales. We find existence of positive solutions by constructing the Green's function and studying its positivity eigenvalue intervals. Two examples are given to

A Note On Matrix Refinement Equations

, 1998
. Refinement equations involving matrix masks are receiving a lot of attention these days. They can play a central role in the study of refinable finitely generated shift-invariant spaces, multiresolutions generated by more than one function, multi ...

Infinitely many homoclinic solutions for nonlinear p-Laplacian partial difference equations without Ambrosetti-Rabinowitz condition

Demonstratio Mathematica
In this paper, we explore the existence of infinitely many homoclinic solutions for nonlinear p-Laplacian partial difference equations by variational methods in combination with the Symmetric Mountain Pass Theorem.

© Hindawi Publishing Corp. A NECESSARY AND SUFFICIENT CONDITION FOR THE EXISTENCE Of A UNIQUE SOLUTION OF A DISCRETE BOUNDARY VALUE PROBLEM

, 2002
A kth-order linear difference equation with constant coefficients subject to bound-ary conditions is considered. A necessary and sufficient condition for the existence of a unique solution for such a boundary value problem is established.

Error Estimations of a Sigma-Delta Converter

, 1997
In this paper an exact model for a basic, first order sigma-delta-modulator is derived by means of a difference equation. The solution of this difference equation provides an explicit description of the relation between the analog input and the digital ...
