Local dependence of the mod p Jacquet–Langlands correspondence

Let m\mathfrak{m} be a maximal ideal of the Hecke algebra, with associated Galois representation ρˉ\bar{\rho}. Let F[m]\mathbf{F}[\mathfrak{m}] denote the corresponding Hecke-isotypic representation, and let πp(ρˉ)\pi^p(\bar{\rho}) denote its prime-to-pp automorphic factor. Mod pp Jacquet–Langlands conjecture. There is a D×(Q)D^{\times}(\mathbb{Q})-equivariant isomorphism

F[m]σπp(ρˉ),\mathbf{F}[\mathfrak{m}] \simeq \sigma \otimes \pi^p(\bar{\rho}),

where σ\sigma is a D×(Qp)D^{\times}(\mathbb{Q}_p)-representation depending only on the restriction ρˉp\bar{\rho}_p. The conjecture formulates the expected factorization into a local representation at pp and the prime-to-pp part, with the local factor determined solely by local Galois data.
