摘要:I will first review the Frobenius structure on the Bessel differential equation whose Frobenius traces are certain  Kloosterman sums. Recently, there are two generalizations of this story (corresponding to GL_2-case) for reductive groups: one is due to Frenkel and Gross from the viewpoint of the Bessel differential equation; another one, due to Heinloth, Ngô and Yun, uses the geometric Langlands correspondence to produce l-adic sheaves. I will report my joint work with Xinwen Zhu, where we study the p-adic aspect of this theory and unify previous two constructions.
