The pp-adic Yoshida-invariant conjecture for CM fields

From papers

Let KK be a CM-field abelian over a totally real field FF, with conductor fK/F\mathfrak f_{K/F}, and assume that pι\mathfrak p_\iota splits completely in K/FK/F. Let χ\chi' be an odd character of Gal(K/F)\operatorname{Gal}(K/F), let χC^fK/F\chi\in\widehat C_{\mathfrak f_{K/F}} correspond to χ\chi' under the Artin map, and let Yp(χpι,ι)Y_p(\chi_{\mathfrak p_\iota},\iota) be the associated pp-adic Yoshida invariant. Here ρ\rho is the unique complex conjugation on KK, hKh_K is the class number of KK, and αK,ι~\alpha_{K,\tilde\iota} is the associated algebraic number. The pp-adic Yoshida-invariant conjecture. One has

Yp(χpι,ι)=L(0,χ)2hKσGal(K/F)χ(σ)logpι~(αK,ι~σραK,ι~σ).Y_p(\chi_{\mathfrak p_\iota},\iota)=\frac{L(0,\chi')}{2h_K}\sum_{\sigma\in\operatorname{Gal}(K/F)}\chi'(\sigma)\log_p\tilde\iota\left(\frac{\alpha_{K,\tilde\iota}^{\sigma\rho}}{\alpha_{K,\tilde\iota}^{\sigma}}\right).

This gives an explicit formula for the pp-adic correction term associated with Yoshida's invariants and refines the pp-adic analogue of the Stark conjecture. The source states no resolution status.
