Hyers-Ulam-Rassias Stability of Functional Equations in Nonlinear Analysis (Springer Optimization and Its Applications)

From the reviews:

...I am more than happy to write my opinion on Soon-Mo Jung’s book, as a new addition in this rapidly growing field of mathematics, which will help interested mathematicians and graduate students to understand further this beautiful domain of research... The book contains 14 chapters...concludes with a very useful bibliography of 364 references and an index. It will definitely guide mathematics students to a decisive first step into this abstract, yet intriguing, field of mathematics.

The author has succeeded in presenting to both mathematicians and graduate students an invaluable source of essential mathematics. The book will certainly before a standard  reference for stability of functional equations in nonlinear analysis.

“This book is intended to provide an overview of the theory of the stability of functional equations. It is very useful for undergraduate/graduate students and also for anyone interested in Hyers-Ulam stability problems. The book is well written; the style is very accessible and clear.” (Paşc Găvruţa, Mathematical Reviews, Issue 2012 c)

“This interesting book is devoted to an exposition of some new significant results of the Hyers-Ulam-Rassias stability of functional equations, difference equations and related topics in Functional Analysis. ... This book is well written in a concise, clear and readable style. ... The book is a good source for specialists and graduate students working in functional equations.” (Mohammad Sal Moslehian, Zentralblatt MATH, Vol. 1221, 2011)
