Non-abelian base change for symmetric power liftings of holomorphic modular forms

Number Theory 2024-06-10 v2

Abstract

Let ff be a non-CM Hecke eigenform of weight k2k \geq 2. We give a new proof of some cases of Langlands functoriality for the automorphic representation π\pi associated to ff. More precisely, we prove the existence of the base change lifting, with respect to any totally real extension F/QF / \mathbb{Q}, of any symmetric power lifting of π\pi.
