This book is a collection of three introductory tutorials coming out of three courses given at the CIMPA Research School “Galois Theory of Difference Equation

From the reviews: "This is a great book, which will hopefully become a classic in the subject of differential Galois theory. [...] the specialist, as well as th

This book shows how Lie group and integrability techniques, originally developed for differential equations, have been adapted to the case of difference equatio

Differential Galois theory is an important, fast developing area which appears more and more in graduate courses since it mixes fundamental objects from many di

The roots of the modern theories of differential and $q$-difference equations go back in part to an article by George D. Birkhoff, published in 1913, dealing wi
