In mathematics, the theta correspondence or Howe correspondence is a mathematical relation between representations of two groups of a reductive dual pair. The local theta correspondence relates irreducible admissible representations over a local field, while the global theta correspondence relates irreducible automorphic representations over a global field.

The theta correspondence was introduced by Roger Howe in Howe (1979). Its name arose due to its origin in André Weil's representation theoretical formulation of the theory of theta series in Weil (1964). The Shimura correspondence as constructed by Jean-Loup Waldspurger in Waldspurger (1980) and Waldspurger (1991) may be viewed as an instance of the theta correspondence.

Statement

Howe duality conjecture

Define ${\displaystyle {\mathcal {R}}({\widetilde {G}},\omega _{\psi })}$ the set of irreducible admissible representations of ${\displaystyle {\widetilde {G}}}$, which can be realized as quotients of ${\displaystyle \omega _{\psi }}$. Define ${\displaystyle {\mathcal {R}}({\widetilde {H}},\omega _{\psi })}$ and ${\displaystyle {\mathcal {R}}({\widetilde {G}}\cdot {\widetilde {H}},\omega _{\psi })}$, likewise.

The Howe duality conjecture asserts that ${\displaystyle {\mathcal {R}}({\widetilde {G}}\cdot {\widetilde {H}},\omega _{\psi })}$ is the graph of a bijection between ${\displaystyle {\mathcal {R}}({\widetilde {G}},\omega _{\psi })}$ and ${\displaystyle {\mathcal {R}}({\widetilde {H}},\omega _{\psi })}$.

The Howe duality conjecture for archimedean local fields was proved by Roger Howe.^[6] For ${\displaystyle p}$-adic local fields with ${\displaystyle p}$ odd it was proved by Jean-Loup Waldspurger.^[7] Alberto Mínguez later gave a proof for dual pairs of general linear groups, that works for arbitrary residue characteristic. ^[8] For orthogonal-symplectic or unitary dual pairs, it was proved by Wee Teck Gan and Shuichiro Takeda. ^[9] The final case of quaternionic dual pairs was completed by Wee Teck Gan and Binyong Sun.^[10]
