Determinant condition for Taylor–Wiles Galois lifts

About 12 years old · traced to

Let QQ be an auxiliary Taylor–Wiles set, let ρ‾m\overline{\rho}_{\mathfrak m} be the residual representation, let μ\mu be the specified character, and let rm,Qr_{{\mathfrak m},Q} be the determinant-μ\mu twist of the conjectural lift. Define

SQ=(ρ‾m,μ,{Λv}v∈S∪{O[Δv]}v∈Q,{Dv△}v∈Sp∪{DvTW}v∈Q){\mathcal S}_Q=(\overline{\rho}_{\mathfrak m},\mu,\{\Lambda_v\}_{v\in S}\cup\{{\mathcal O}[\Delta_v]\}_{v\in Q},\{{\mathcal D}_v^\triangle\}_{v\in S_p}\cup\{{\mathcal D}_v^\mathrm{TW}\}_{v\in Q})

with Λv=O⟦OFv×(p)n−1⟧\Lambda_v={\mathcal O}\llbracket{\mathcal O}_{F_v}^{\times}(p)^{n-1}\rrbracket for v∈Spv\in S_p, and with ΛS=Λ\Lambda_S=\Lambda and ΛS∪Q=Λ[ΔQ]\Lambda_{S\cup Q}=\Lambda[\Delta_Q]. Determinant-type conjecture. The lifting rm,Qr_{{\mathfrak m},Q} is of type SQ{\mathcal S}_Q. This specifies the local deformation conditions expected of the Taylor–Wiles lift and is part of the deformation-theoretic input for patching; the source gives no resolution status.
