Abstract
We present a collection of conjectural trace identities and explain why they are equivalent to base change and descent of automorphic representations of GLn(AF ) along nonsolvable extensions (under some simplifying hypotheses). The case n = 2 is treated in more detail and applications towards the Artin conjecture for icosahedral Galois representations are given.
