## 1. Introduction

In many engineering and applied sciences fields, researchers encounter a special class of problems known as boundary value problems, or characteristic value problems. The desired or achieved solution for this kind of problems is required to satisfy given boundary conditions.In real-world applications and their related problems, there are always some boundary conditions to meet for imitating the real case with simplified mathematical model with its boundary of initial conditions. Based on this idea, characteristic value problems of ODE and ODEs systems will always be a center of attention of scientific research.Characteristic-value problems are a subset of boundary value problems because the governing ODE is a boundary value problem; except in characteristic value problems we are also concerned with the characteristic value, or eigenvalue, that governs the behavior of the boundary value problem.The main focus of this special issue is on the novel analytical, numerical and soft computing methods and approaches which hopefully have potential value for researchers of characteristic value problems of ODE and ODEs systems and general characteristic value problems. The special issue has become an international forum for researchers to summarize the most recent developments and ideas in the field, with a special emphasis given to research results obtained within the last five years. The topics which are covered here in this special issue include below-mentioned research fields and related research titles. The special issue contains 14 original papers, selected by the editors so as to present the most significant results in general research fields given below.
