Bressoud D.M. Factorization and Primality Testing
Монография. Серия "Undergraduate Texts in Mathematics".
New York: Springer-Verlag, 1989. - xiii + 237 p.
ISBN: 0-387-97040-1.
Эта книга сфокусирована на единственной проблеме: как факторизовать большое целое число или доказать его простоту. От древнего решета Эратосфена до многократного полиномиального квадратичного решета (MPQS) и методов эллиптической кривой, открытых несколько лет назад, в этом вполне автономном тексте дается как обзор наследия, так и введение в современные исследования в этой сфере с сильным акцентом на алгоритмы. Книга может также использоваться в качестве введения в теорию чисел.
