From the reviews: "The book under review deals with Diophantine analysis from a number-theoretic point of view. ... Each chapter ends with exercises, ranging from simple to quite challenging problems. The clarity of the exposition is the one we expect from the author of two highly successful books on computational number theory ... and makes this volume a must-read for researchers in Diophantine analysis." (Philosophy, Religion and Science Book Reviews, bookinspections.wordpress.com, October, 2013) "This is the first volume of a highly impressive two-volume textbook on Diophantine analysis. ... Readers are presented with an almost overwhelming amount of material. This ... text book is bound to become an important reference for students and researchers alike." (C. Baxa, Monatshefte fur Mathematik, Vol. 157 (2), June, 2009) "Cohen (Universite Bordeaux I, France), an instant classic, uniquely bridges the gap between old-fashioned, naive treatments and the many modern books available that develop the tools just mentioned ... . Summing Up: Recommended. ... Upper-division undergraduates through faculty." (D. V. Feldman, CHOICE, Vol. 45 (5), January, 2008) "Number Theory, is poised to fill the gap as a core text in number theory ... . So, all in all, Henri Cohen's ... Number Theory are, to any mind, an amazing achievement. The coverage is thorough and generally all but encyclopedic, the exercises are good, some are excellent, some will keep even the best-prepared student busy for a long time, and the cultural level of the book ... is very high."
