Diophantine Approximations

Large grey octavo with brownish-red stamping on spine; vi, 68 pages: diagram; 24 cm. "At the 1960 summer meeting of the Mathematical Association of America it was the authors privilege to deliver the Earle Raymond Hedrick lectures. This monograph is an extension of those lectures, many details having been added that were omitted or mentioned only briefly in the lectures. The monograph is self-contained. It does not offer a complete survey of the field. [.]An attempt has been made, in a section entitled "Further results" at the end of each chapter, to provide a bibliographic account of closely related work. These sections also give the sources from which the proofs are drawn." -- Preface. "Diophantine approximation is a branch of number theory concerned with how closely real numbers can be approximated by rational numbers.[.]Diophantine approximation is relevant to cryptography (especially algorithms reliant on number theory), computer science, signal processing, and even physics, particularly when analyzing periodicity and resonance in physical systems." - WorldCat.
