Recently I taught short courses on functional equations at several universities (Barcelona, Bern, Graz, Hamburg, Milan, Waterloo). My aim was to introduce the m

Many books have been written on the theory of functional equations, but very few help readers solve functional equations in mathematics competitions and mathema

The book provides the reader with the different types of functional equations that s/he can find in practice, showing, step by step, how they can be solved.A ge

Introduction to Functional Equations grew out of a set of class notes from an introductory graduate level course at the University of Louisville. This introduct

This book discusses the rapidly developing subject of mathematical analysis that deals primarily with stability of functional equations in generalized spaces. T
