Geometric Langlands correspondence

In mathematics, the geometric Langlands correspondence relates algebraic geometry and representation theory. It 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. The correspondence is named for the Canadian mathematician Robert Langlands, who formulated the original form of it in the late 1960s.

The geometric Langlands conjecture asserts the existence of the geometric Langlands correspondence.
