The weak local Langlands interpolation conjecture for framed deformation rings

About 14 years old · traced to

Let LL be the local field, let ρ‾ \overline{\rho} be a residual representation, let Rρ‾□R_{ \overline{\rho}}^{\Box} be its framed deformation ring, and let (A[L,π])m(A_{[L,\pi]})_{\mathfrak m} be the relevant localization of the integral Bernstein center. A map from (A[L,π])m(A_{[L,\pi]})_{\mathfrak m} to Rρ‾□R_{ \overline{\rho}}^{\Box} is an interpolating map. It interpolates the characteristic-zero semisimple local Langlands correspondence when, on characteristic-zero points, it sends a framed deformation ρ\rho to the point corresponding to its semisimple local Langlands parameter.

Weak local Langlands interpolation conjecture. For any ρ‾ \overline{\rho}, there is a map

LL⁡:(A[L,π])m→Rρ‾□\operatorname{LL}: (A_{[L,\pi]})_{\mathfrak m} \rightarrow R_{ \overline{\rho}}^{\Box}

that interpolates the characteristic-zero semisimple local Langlands correspondence.

This conjecture is motivated by the preceding interpolation proposition and, conditional on the stated proposition, follows from the existence of a universal representation π(ρ□)\pi(\rho^{\Box}). The source gives no resolution status.
