Basic Modern Theory of Linear Complex Analytic $q$-Difference Equations John T. Goldthwait physicians encounter patients whose presentationsThe 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 with the three ""sister theories"" of differential, difference and $q$ difference equations. This book is about $q$ difference equations and focuses on techniques inspired by differential equations, in line with Birkhoff's work, as revived over the last three decades. It follows the approach of
