In mathematics, the geometric Langlands correspondence is a reformulation of the Langlands correspondence obtained by replacing the number fields appearing in the original number theoretic version by function fields and applying techniques from algebraic geometry.[1] The geometric Langlands correspondence relates algebraic geometry and representation theory.
The specific case of the geometric Langlands correspondence for general linear groups over function fields was proven by Laurent Lafforgue in 2002, where it follows as a consequence of Lafforgue's theorem.

History
In mathematics, the classical Langlands correspondence is a collection of results and conjectures relating number theory and representation theory. Formulated by Robert Langlands in the late 1960s, the Langlands correspondence is related to important conjectures in number theory such as the Taniyama–Shimura conjecture, which includes Fermat's Last Theorem as a special case.[1] Establishing the Langlands correspondence in the number theoretic context has proven extremely difficult. As a result, some mathematicians have posed the geometric Langlands correspondence.[1]
Langlands correspondences can be formulated for global fields (as well as local fields), which are classified into number fields or global function fields. The classical Langlands correspondence is formulated for number fields. The geometric Langlands correspondence is instead formulated for global function fields, which in some sense have proven easier to deal with.
In 2002, the geometric Langlands correspondence was proven for general linear groups over a function field by Laurent Lafforgue.[2]
Connection to physics
In a paper from 2007, Anton Kapustin and Edward Witten described a connection between the geometric Langlands correspondence and S-duality, a property of certain quantum field theories.[3]
In 2018, when accepting the Abel Prize, Langlands delivered a paper reformulating the geometric program using tools similar to his original Langlands correspondence.[4][5]
