Langlands program for -adic coefficients and the petites camarades conjecture
arXiv:1111.2479
Abstract
In this paper, we prove that, if Deligne's "petites camarades conjecture" holds, then a Langlands type correspondence holds also for -adic coefficients on a smooth curve over a finite field. We also prove that any overconvergent -isocrystal of rank less than or equal to 2 on a smooth variety is -mixed.
