On quadratic extensions of number fields and Iwasawa invariants for basic Z3-extensions
Let Z3 be the ring of 3-adic integers. For each number field F, let F∞,3 denote the basic Z3-extension over F; let λ3(F) and μ3(F) denote respectively the Iwasawa λ- and μ-invariants of F∞,3/F. Here a number field means a finite extension over the rational field Q contained in the …
