Extensively covers the Catalan Conjecture and Mihailescu´s subsequent proof
Includes thorough exposition of cyclotomic fields
Provides a bridge between number theory and classical analysis
In 1842 the Belgian mathematician Eugène Charles Catalan asked whether 8 and 9 are the only consecutive pure powers of non-zero integers. 160 years after, the question was answered affirmatively by the Swiss mathematician of Romanian origin Preda Mihailescu. In other words, 32 – 23 = 1 is the only solution of the equation xp – yq = 1 in integers x, y, p, q with xy != 0 and p, q >= 2.
In this book we give a complete and (almost) self-contained exposition of Mihailescu´s work, which must be understandable by a curious university student, not necessarily specializing in Number Theory. We assume a very modest background:a standard university course of algebra, including basic Galois theory, and working knowledge of basic algebraic number theory.
