Fukaya–Kato equivariant local Tamagawa-number conjecture

Let Λ\Lambda be the Iwasawa algebra of the relevant pp-adic Lie group, let Λ~\widetilde\Lambda be its unramified coefficient extension, and let T\mathbb T be the associated big Galois representation. For every finite coefficient representation ρ:GGLn(O)\rho:G\to\operatorname{GL}_n(\mathcal O), write T(ρ)T(\rho^*) for the specialized lattice. Equivariant local Tamagawa-number conjecture. There exists a unique isomorphism

ϵp,Λ(T):1Λ~(DΛ(RΓ(Qp,T))DΛ(T))Λ~\epsilon_{p,\Lambda}(\mathbb T):\mathbf{1}_{\widetilde\Lambda}\to\bigl(\mathcal D_\Lambda(\mathrm{R}\Gamma(\mathbb Q_p,\mathbb T))\mathcal D_\Lambda(\mathbb T)\bigr)_{\widetilde\Lambda}

such that

OnΛϵp,Λ(T)=ϵp,O(T(ρ));\mathcal O^n\otimes_\Lambda\epsilon_{p,\Lambda}(\mathbb T)=\epsilon_{p,\mathcal O}(T(\rho^*));

its assignment is required to satisfy the compatibility conditions described in the source. The source states that the commutative-Λ\Lambda case was proved by S. Yasuda, while the noncommutative case was expected to follow by extending those methods.
