Langlands reciprocity (general)

The general correspondence is known for GL(1) (class field theory) and in many cases for GL(2), plus pieces beyond. Each new case has taken years and has usually settled famous problems along the way. The geometric version was proved in 2024, and the arithmetic version remains the central open problem of the field.

Posed 1967, Robert Langlands.
