On the unramified extensions of the prime cyclotomic number field and its quadratic extensions
Published online by Cambridge University Press: 22 January 2016
Extract
It is interesting to know what kinds of primes are the factors of the class number of an algebraic number field, and especially to find ones being prime to the degree. About this matter it is desirable to construct the unramified Abelian extensions plainly. In this paper we shall show some of them for the prime cyclotomic number field and its quadratic extensions using the units of subfields.
