In this chapter, we introduce the study of disconjugacy of n th order dynamic equations on
time scales. Disconjugacy of ordinary differential equations is thoroughly studied and has a …

We dedicate this book to our family members who complete us. In particular, M. Benchohra's
dedication is to his wife, Kheira, and his children, Mohamed, Maroua, and Abdelillah; J …

The study of dynamic equations on time scales, which goes back to its founder Stefan Hilger
(1988), is an area of mathematics that has recently received a lot of attention. It has been …

Infinite interval problems abound in nature and yet until now there has been no book dealing
with such problems. The main reason for this seems to be that until the 1970's for the infinite …

This book summarizes the qualitative theory of differential equations with or without delays,
collecting recent oscillation studies important to applications and further developments in …

In this paper we offer a form of self-adjoint differential equations on time scales so that the
associated Green's function is found symmetric in the usual sense. For this purpose together …

We are concerned with proving the existence of positive solutions of general two point
boundary value problems for the nonlinear equation Lx (t):=−[r (t) xΔ (t)] Δ=/tf (t, x (t)). We will …

In this paper, we obtain some basic results of quaternion algorithms and quaternion calculus
on time scales. Based on this, a Liouville formula and some related properties are derived …

We are concerned with the calculus on measure chains which is a unified approach to
continuous and discrete calculus. An excellent introduction to this subject is given by S …
