The vanishing conjecture for the modified equivariant local epsilon term

Let KK be a finite extension of Qp{\mathbb Q}_p, let N/KN/K be a finite Galois extension with Galois group GG, and retain the notation R~N/K\tilde R_{N/K} and K0(Λ~,Ω~)K_0(\tilde\Lambda,\tilde\Omega) introduced above. Modified epsilon-term vanishing conjecture. Under the current assumptions,

R~N/K=0in K0(Λ~,Ω~).\tilde R_{N/K}=0\quad\text{in }K_0(\tilde\Lambda,\tilde\Omega).

In the case χnrGN1\chi^{\mathrm{nr}}|_{G_N}\ne 1, this is precisely the reformulation of the preceding equivariant local epsilon-constant conjecture, while the general relationship is established in the surrounding discussion; no resolution is stated here.
