Abstract
We correct the faulty formulas given in a previous article and we compute the defect group for the Iwasawa invariants attached to the S-ramified T-decomposed a belian pro--extensions on the Z-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-extension of abelian fields.
