Diophantine approximation may be roughly described as the branch of number theory concerned with approximations by rational numbers; or rather, this constituted the original motivation. That such questions have attracted continued attention is undoubtedly substantially due to their relevance for another, more ancient, topic: the theory of Diophantine equations, namely those whose solutions have to be found in integers or rationals, possibly in a finite extension of Q. The connections between the subjects, which had already been observed by Lagrange and Legendre, were explicitly pointed out by the Norwegian A. Thue; in 1909 he proved a finiteness theorem for Diophantine equations which for the first time included whole families of equations, of arbitrarily large degree. At that time they could be treated only occasionally, and merely with ad hoc methods, albeit ingenious ones. Thue’s theorem relied solely on a result which limited the accuracy of the rational approximations to algebraic numbers (a previous result had been obtained by Liouville, but it was too weak for applications to equations).
