Fundemental system of cyclotomoc

WebWritten by two leading workers in the field, this short and elegant book presents in full detail the simplest proof of the "main conjecture'' for cyclotomic fields. Its motivation stems not only from the inherent beauty … WebKeywords: Cyclotomic fields, Roots of unity I. Introduction The objective of this paper is to lay the foundations for efficient computation in cyclotomic fields. In particular, we show that the fundamental operations in a cyclotomic field can be performed very efficiently by the use of a certain integral basis.
