Let \(F\) be a totally real abelian number field with ring of integers \(\mathfrak o_F\), \(p\) an odd prime not dividing the degree of \(F\) over \(\mathbb Q\) and \(F_p\), the product of the completions of \(F\) at the places dividing \(p\). Among others the author proves the following:
If \(i\ge 3\) is an odd integer and if the Kubota-Leopoldt \(p\)-adic \(L\)-function \(L_p(F,\omega^{i-1},s)\) is non-zero at \(s=i\), the morphism \[K_{2i-1}(\mathfrak o_F)/\text{torsion} \to K_{2i-1}(F_p)/\text{torsion} \] is injective. The proof uses the comparison between \(K\)-theory and étale cohomology for global and local fields developed by the author in [Invent. Math. 55, 251–295 (1979; Zbl 0437.12008)].
