The local Tamagawa number conjecture for h0(K)(j)h^0(K)(j)

Let KK be a number field, let pp be a prime, and let jj be a positive integer. Write Kp=KQQpK_p=K\otimes_{\mathbb{Q}}\mathbb{Q}_p, let Zp(j)\mathbb{Z}_p(j) denote the jj-th Tate twist, and let ϑjloc\vartheta_j^{\rm loc} be the local period isomorphism defined in the preceding construction. A Zp\mathbb{Z}_p-basis means a generator of the displayed rank-one determinant module.

The local Tamagawa number conjecture. For every positive integer jj there exists a unique Zp\mathbb{Z}_p-basis

zjdetZp1(RΓ(Kp,Zp(j)))ZpdetZp1(σ:KCZp(j))z_j \in {\det}_{\mathbb{Z}_p}^{-1}(\operatorname{R}\Gamma(K_p,\mathbb{Z}_p(j))) \otimes_{\mathbb{Z}_p} {\det}^{-1}_{\mathbb{Z}_p} \left( \bigoplus_{\sigma: K \hookrightarrow \mathbb{C}} \mathbb{Z}_p(j)\right)

with

ϑjloc(zj)=ζK,{p}(1j)ζK,{p}(j).\vartheta_j^{\rm loc}(z_j)= \frac{\zeta_{K, \{p\}}^\ast(1-j)}{\zeta_{K,\{p\}}^\ast(j)}.

This is the local Tamagawa number conjecture for the pair (h0(K)(j),p)(h^0(K)(j),p); the supplied text gives no resolution beyond its formulation.
