The local-global compatibility conjecture for spectral p-adic Jacquet-Langlands

About 8 years old · traced to

Let E⊂Qp‾E\subset\overline{\mathbb{Q}_p} be a finite extension of Qp\mathbb{Q}_p, and let ρ:GQ→GL⁡2(E)\rho:G_{\mathbb{Q}}\to\operatorname{GL}_2(E) be an odd continuous absolutely irreducible representation unramified outside finitely many places. Write ρl\rho_l for its restriction to GQlG_{\mathbb{Q}_l}, let πl\pi_l be the smooth representation of GL⁡2(Ql)=D×(Ql)\operatorname{GL}_2(\mathbb{Q}_l)=D^\times(\mathbb{Q}_l) corresponding to ρl\rho_l for l≠pl\ne p, and let J(ρp)J(\rho_p) be the representation of D×(Qp)D^\times(\mathbb{Q}_p) obtained from the local p-adic Jacquet-Langlands correspondence. Let AEvp\mathcal{A}_{E}^{v_p} denote the global space introduced above. Local-global compatibility conjecture. There is an isomorphism of D×(Qp)D^\times(\mathbb{Q}_p)-representations

Hom⁡D×(Af(p))(⨂l≠pπl,AEvp)≅J(ρp).\operatorname{Hom}_{D^\times(\mathbb{A}_f^{(p)})}\left(\bigotimes_{l\ne p}\pi_l,\mathcal{A}_{E}^{v_p}\right)\cong J(\rho_p).

This conjecture predicts compatibility between the global spectral pp-adic Jacquet-Langlands construction and Scholze's local correspondence. The paper derives consequences for locally algebraic vectors assuming the conjecture; the source does not state a resolution.
