Adler–Mishra–Stevens conjecture on the Bernstein-block local Langlands correspondence

From papers

Let GG be a reductive group, let s=[L,σ]GB(G)\mathfrak{s}=[L,\sigma]_G\in\mathfrak{B}(G) be a Bernstein component, and suppose that the local Langlands correspondence for LL assigns to σ\sigma the enhanced parameter (φσ,ρσ)(\varphi_\sigma,\rho_\sigma). Define

s=[L,(φσ,ρσ)]G.\mathfrak{s}^{\vee}=[L^{\vee},(\varphi_\sigma,\rho_\sigma)]_{G^{\vee}}.

Adler–Mishra–Stevens conjecture. The local Langlands correspondence for LL induces a bijection

Irrs(G)Φes(G).\operatorname{Irr}^{\mathfrak{s}}(G)\xrightarrow{\sim}\Phi_{\mathrm{e}}^{\mathfrak{s}^{\vee}}(G).

This conjecture asserts compatibility of the local Langlands correspondence with Bernstein decompositions, matching the irreducible representations in the block indexed by s\mathfrak{s} with the enhanced LL-parameters in the corresponding dual block. Its resolution is not established by the supplied text.
