ArXiv: Invariant theory for the commuting scheme of symplectic Lie algebras; Algebraic Geometry (math.AG), February 2021. https://arxiv.org/abs/0801.0446: “We propose a proof for conjectures of Langlands, Shelstad and Waldspurger known as the fundamental lemma for Lie algebras and the non-standard fundamental lemma. The proof is based on a study of the decomposition of the l-adic cohomology of the Hitchin fibration into direct sum of simple perverse sheaves.”

Research and Relate: (1) Hitchin fibrations — purely geometric objects, (2) Galois groups in algebraic number theory to automorphic forms and representation theory of algebraic groups over local fields and adeles, (3) the automorphic L-function, L (s, π, ρ), as Langlands discovered, depended not only on the automorphic representation π, but also on an auxiliary finite dimensional representation ρ of a canonically associated dual group or L-group.

Dear Prof. Dr. Ngô Bao Châu:

I spent a few days in Hanoi and Saigon about ten years ago. My very first interactions with Hanoi were in 1969 and 1970. That’s a long story.

In 2014 I picked up Ed Frenkel’s Love & Math and was introduced to Robert Langlands, of course, and to others like Drinfeld and Gelfand. It is a very steep learning curve; and like most, I have barely scratched the surface.

Your work quickly came to my attention and it has taken until today to humble myself and confess that I will probably die before even grasping the essentials… even after spending time on the IAS papers of so many of the primary program authors like yourself.

My working summary page about your work is here: https://81018.com/2021/11/18/chau/. (this page). It is just starting.

May I ask you a few questions? It will be in light of my current work to follow-up this page: https://81018.com/almost/ The next article will open with comments about the Langlands programs understanding of place and role of infinity, pi, and infinitesimal spheres? Thank you.

Most sincerely,

Bruce
