Robert Langlands

Robert Langlands, Professor Emeritus in the School of Mathematics, first came to the Institute as a Member in 1962 and joined the Faculty in 1972. His visionary work, known collectively as the Langlands program, has had a deep influence across a broad sweep of mathematics and parts of theoretical physics.

Writing for NRC Handelsblad, Robbert Dijkgraaf, IAS Director and Leon Levy Professor, likens IAS Professor and Abel Prize Laureate Robert Langlands’s program, “a deep connection between two completely different parts of mathematics: on the one hand, numbers and their relations, on the other hand, geometrical patterns and their symmetries,” to a mathematical Rosetta Stone.

Explore a collection of Robert Langlands’s papers, as well as some of his lectures and correspondence, on topics ranging from functoriality, representation theory, and base change to endoscopy, Shimura varieties, percolation, and geometric theory.

The fundamental lemma has been described as a gross understatement. Says Andrew Wiles, a Visitor in the School of Mathematics and an Institute Trustee, “At first, it was thought to be a minor irritant, but it subsequently became clear that it was not a lemma but rather a central problem in the field.”
