equations. It is without question one of the most through reviews I have seen, on

any subject. Those doing research in this _eld would be well advised to refer to this

work. The author consistently poses questions to researchers who are looking for open

problems.' (Mathematical Reviews)

`The monograph is an excellent account of the various techniques available in

the literature to prove existence and uniqueness of various boundary value problems

which occur in applications. Graduate students and research mathematicians will

_nd it very useful.' (Zentralblatt fur Mathematik)

is well written and is easy to read. This book covers over 400 recent publications.

This book should not only be of interest to mathematicians and statisticians but

also to electrical engineers, biologists, economists, psychologists, and sociologists to

name a few. This indeed is a very good book to have in ones own personal library.'

(Mathematical Reviews)

`This new monograph combines all aspects of the theory and methods of solutions

of di_erence equations and their applications in real world problems providing in{

depth coverage of more than 400 recent publications. This monograph with the

wealth of information it contains is very well come.' (Newsletter on Computational

and Applied Mathematics)

`This book contains a complete account of standard results concerning di_erence

equations, as well as an extensive discussion of recent papers concerning the theory

and practice of their solutions. This book should be useful both as textbook and for

reference.' (Mathematika)

`This book is essential for the enrichment of knowledge in mathematics, physics

and statistics. The comprehensive compilation of the book is useful for researchers of

natural philosophy.' (Indian J. Physics)

`Comprehensive treatment develops discrete versions of Rolle's, mean value, Kneser's

theorems_ _ _' (The American Mathematical Monthly)

`This excellent monograph combines all aspects of the theory and methods of

of more than 400 recent publications. It serves as a basic reference for mathematicians

and users of mathematics interested in di_erential and di_erence equations and their

applications.' (Acta Sci. Math. Szeged)

`It is a de_nite reference for applied mathematicians, numerical analysts, physicists,

engineers, and graduate{level students in courses on di_erence equations.' (INSPEC

The Institute of Electrical Engineers)

`Focusing on a wide range of possible mathematical uses, the book o_ers various

(4) R.P. Agarwal and V. Lakshmikantham, Uniqueness and Nonuniqueness Criteria

for Ordinary Di_erential Equations, World Scienti_c, Singapore, 1993, p. 312.

`The book is devoted to a branch of the theory of di_erential equations that is

classical on the one hand but still alive and developing on the other hand. The book

is very interesting and well written. It is warmly recommended to any student in

analysis and to any specialist in the theory of di_erential equations.' (Mathematical

Reviews and Zentralblatt fur Mathematik)

(5) R.P. Agarwal and P.J.Y.Wong, Error Inequalities in Polynomial Interpolation

and Their Applications, Kluwer Academic Publishers, Dordrecht, 1993, p.365.

`A main theme of this book lies behind the selection and organization of the material

in it is the use of interpolation in the theory of ordinary di_erential equations_ _ _ :

It will no doubt _nd uses among specialists in di_erential equations. Otherwise, the

wealth of detail and the precision of the error estimates in it go beyond what is generally

available in book or monograph form and commend the work to a more general

audience.' (Journal of Approximation Theory)

and Di_erence Equations, Kluwer Academic Publishers, Dordrecht, 1995,

p.393.

`The monograph under review presents a complete survey of results related to

the Opial's inequality developed over the last three decades_ _ _. The book under

review is very well written and most of the material is presented with detailed proofs.

The book can be warmly recommended not only to specialist working in the area of

mathematical analysis and applications but also to graduate students, engineers and

researchers in the applied sciences.' (Zentralblatt fur Mathematik)

(8) R.P. Agarwal and P.J.Y. Wong, Advanced Topics in Di_erence Equations,

Kluwer Academic Publishers, Dordrecht, 1997, p.507.

`One of the specialists in the _eld is without doubt Ravi P Agarwal. His previous

book Di_erence Equations and Inequalities (1992) is a survey of the theory of

di_erence equations and contains a wealth of information for the researchers. This

new book, co{authored by Patricia J. Y. Wong, can be seen as an update of the _rst

one_ _ _ : The results in this book are of great interest to other specialists in the _eld.

This book o_er an easy way to get access to them.' (Mathematical Reviews)

`The book contains a collection of recent results and it will serve as a reference

book for researchers in discrete dynamical systems and their applications and reader

will also _nd material, which is not available in other books on di_erence equations.

It will also be of interest to graduate students interested in the theory of _nite di_erence

equations and their applications. The presentation is clear and it is a welcome

addition to the literature.' (Zentralblatt fur Mathematik)

(9) R.P. Agarwal, Focal Boundary Value Problems for Di_erential and Di_erence

Equations, Kluwer Academic Publishers, Dordrecht, 1998, p.289.

`Agarwal's great knowledge of the literature in this area makes this book very

appealing. The book will be useful for a graduate course concerned with boundary

value problems for either di_erential equations or di_erence equations. It also would

be an excellent book for mathematicians doing research in this area.' (Mathematical

Reviews)

`The majority of the book is devoted to some of the recent developments by the

authors. The book should be a good reference book and the extensive bibliography

could prove to be very helpful. In addition, the examples at the end of each chapter

are a good source of illustrative material.' (Mathematical Reviews)

`The authors study systematically various techniques about oscillation and nonoscillation

of each type of equations. There are numerous examples in each chapter and

each chapter ends with detailed historical notes and an extensive list of references.

The book is very readable and it is a valuable source and an important contribution

to oscillation theory.' (Mathematical Reviews)

(18) R.P. Agarwal and D. O'Regan, Singular Di_erential and Integral Equations

`The authors have produced a monograph in which they present some of the

recent development in existence of solutions theory of nonlinear singular integral and

di_erential equations. In addition to theory, the monograph focuses on applications.

Much of the material focuses on recent developments of the authors. A primary

purpose of the monograph is to provide a readable account and introduce the material

to a broader audience.' (Mathematical Reviews)

`This is truly a compendium of many di_erent results, all having a relation in

some way to results which may or may not be fairly well known for the continuous

case. One of the very useful features of this book is the discussion at the end of each

chapter of the results presented and references to the original sources, as far as the

authors are aware. Moreover, the authors have included a large number of examples

throughout which serve to illustrate the many and varied results which are obtained.

All of the authors are very well known in oscillation theory and have all contributed

a great deal to this area. It is indeed a useful addition to the literature to have such

a comprehensive survey of the area and to point the direction to new results. It will

serve as a valuable reference in the area for many years to come.' (Mathematical
