Beyond Endoscopy

Beyond Endoscopy will feature talks by Ngô Bảo Châu, Robert Langlands, Ali Altuğ, Bill Casselman, Shuyang Cheng, Tasho Kaletha, Freydoon Shahidi, Jasmin Matz, and James Arthur.

The Work of Robert Langlands

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 Shimura varieties to endoscopy, percolation, and geometric theory. 

The Fundamental Lemma

When he heard of the progress being made with the fundamental lemma, whose proof was provided by Ngô Bảo Châu in 2010,  Robert Langlands began working in an area he calls “beyond endoscopy.” Primary among Langlands’s interests is using the Arthur-Selberg trace formula to resolve the principle of functoriality beyond endoscopy. “I hope that with the fundamental lemma at hand," said Langlands, "we will see in the coming years great progress both with functoriality and with the general theory of Shimura varieties.”
