Gauss made early inroads in the theory of cyclotomic fields, in connection with the geometrical problem of constructing a regular n -gon with a compass and straightedge. Lanf pages Title Page. Iwasawa Invariants for Measures. Leopoldt concentrated on a fixed cyclotomic field, and established various p-adic analogues of the classical complex analytic class number formulas.

The geometric problem for a general n can be reduced to the following question in Galois theory: I am specifically interested in connection of cyclotomic fields and Bernoulli numbers. The Ideal Class Group of Qup. Iwasawa viewed cyclotomic fields as being analogues for number fields of the constant field extensions of algebraic geometry, and wrote a great sequence of papers investigating towers of cyclotomic fields, and more generally, Galois extensions of number fields whose Galois group is isomorphic to the additive group of p-adic integers.
