The integral logarithm in Iwasawa theory : an exercise
Journal de théorie des nombres de Bordeaux, Volume 22 (2010) no. 1, pp. 197-207.

Let l be an odd prime number and H a finite abelian l-group. We describe the unit group of Λ [H] (the completion of the localization at l of l [[T]][H]) as well as the kernel and cokernel of the integral logarithm L:Λ [H] × Λ [H], which appears in non-commutative Iwasawa theory.

Soient l un nombre premier impair et H un groupe fini abélien. Nous décrivons le groupe d’unités de Λ [H] (la complétion du localisé de l [[T]][H] en l) ainsi que le noyau et le conoyau du logarithme intégral L:Λ [H] × Λ [H], qui apparaît dans la théorie d’Iwasawa non-commutative.
