On S-ramified T-split Iwasawa modules

Number Theory 2023-12-27 v2

Abstract

We correct the faulty formulas given in a previous article and we compute the defect group for the Iwasawa λ\lambda invariants attached to the S-ramified T-decomposed a belian pro-{\ell}-extensions on the Z{\ell}-cyclotomic extensionof a number field. As a consequence, we extend the results of Itoh, Mizusawa and Ozaki on tamely ramified Iwasawa modules for the cyclotomic Z{\ell}-extension of abelian fields.
