The detailed description of each algorithm allows immediate computer implementation; numerous further hints for implementation are also provided. The book also gives a survey of factoring and primality testing methods, including a detailed description of the number-field sieve algorithm. It ends with a description of available computer package and some useful tables. It contains a large number of exercises algebraic number theory Minh, 971015 Trung tâm Học liệu Trường Đại học Cần Thơ
