The Taylor–Wiles-level Galois lifting conjecture

Let ρm\overline{\rho}_{\mathfrak{m}} be the residual representation from the preceding conjecture, and let (Q,(γv,1,,γv,n)vQ)(Q,(\gamma_{v,1},\dots,\gamma_{v,n})_{v\in Q}) be a Taylor–Wiles datum. Let GF,SQG_{F,S\cup Q} be the Galois group unramified outside SQS\cup Q, and let TSQ(U1p(Q))mQ,1{\mathbb T}^{S\cup Q}(U^p_1(Q))_{\mathfrak{m}_{Q,1}} be the localized Taylor–Wiles-level Hecke algebra.

Taylor–Wiles-level lifting conjecture. If ρm\overline{\rho}_{\mathfrak{m}} is absolutely irreducible, there exists a continuous lifting

ρm,Q:GF,SQGLn(TSQ(U1p(Q))mQ,1)\rho_{\mathfrak{m},Q}:G_{F,S\cup Q}\longrightarrow\operatorname{GL}_n({\mathbb T}^{S\cup Q}(U^p_1(Q))_{\mathfrak{m}_{Q,1}})

whose Frobenius characteristic polynomial at every finite place vSQv\notin S\cup Q is

XnTv1Xn1++(1)iqvi(i1)/2TviXni++(1)nqvn(n1)/2Tvn,X^n-T_v^1X^{n-1}+\cdots+(-1)^iq_v^{i(i-1)/2}T_v^iX^{n-i}+\cdots+(-1)^nq_v^{n(n-1)/2}T_v^n,

and which is of type SQ{\mathcal S}_Q.

This is the refinement of the global Galois representation conjecture required at Taylor–Wiles level. The paper assumes it and does not provide a resolution.
