Locally analytic socle conjecture for GL2(L){\rm GL}_2(L)

Let SΣLS\subseteq\Sigma_L, let ISc(α,h)=C(1,sJ)I^c_S(\alpha,\mathbf h)=C(1,s_J) be the corresponding locally analytic representation, and let S^(Up,E)ρan[mρ]\widehat S(U^{\mathfrak p},E)_{\overline\rho}^{\mathrm{an}}[\mathfrak m_\rho] be the localized locally analytic automorphic representation. Locally analytic socle conjecture. Assuming Hypothesis,

ISc(α,h)S^(Up,E)ρan[mρ]I^c_S(\alpha,\mathbf h)\hookrightarrow\widehat S(U^{\mathfrak p},E)_{\overline\rho}^{\mathrm{an}}[\mathfrak m_\rho]

if and only if SΣ(y)S\subseteq\Sigma(y). This is the locally analytic socle prediction for GL2(L)\mathrm{GL}_2(L) and is equivalent in the paper to the companion-point formulation.
