  "abstract": "Let $K$ be a totally real number field of degree $r$. Let $K_{\\infty}$ denote the cyclotomic $\\mathbb{Z}_{2}$-extension of $K$ and let $L_{\\infty}$ be a finite extension of $K_{\\infty}$, abelian over $K$. The goal of this paper is to compare the characteristic ideal of the $\\chi$-quotient of the projective limit of the narrow class groups to the $\\chi$-quotient of the projective limit of the $r$-th exterior power of totally positive units modulo a subgroup of Rubin-Stark units, for some $\\overline{\\mathbb{Q}_{2}}$-irreducible characters $\\chi$ of $\\mathrm{Gal}(L_{\\infty}/K_{\\infty})$.",
