Abstract Fix an odd prime number p and an abelian field K. Let U (resp. C ) be the projective limit of the semi-local units at p (resp. of the cyclotomic units) of each intermediate field of the cyclotomic Z p-extension K∞/K. We study the Galois module structure of U / C . We generalize results of Iwasawa and Gillard and sharpen a result of Greither.
