Let $\\rho$ be a continuous representation $\\pi(X)\\to GL_n(F)$, where $F=F_l((t))$ with $F_l$ being another finite field of order prime to $q$. Assume that $\\rho|_{\\pi(\\bar{X})}$ is irreducible. De Jong's conjecture says that in this case $\\rho(\\pi(\\bar{X}))$ is finite. As was shown in the original paper of de Jong, this conjecture follows from an existence of an $F$-valued automorphic form corresponding to $\\rho$ is the sense of Langlands. The latter follows, in turn, from a version of the Geometric Langlands conjecture. In this paper we sketch a proof of the required version of the geometric conjecture, assuming that $char(F)\\neq 2$, thereby proving de Jong's conjecture in this case.", "revisions": [ { "version": "v4", "updated": "2006-04-01T23:37:33.000Z" } ], "analyses": { "keywords": [ "finite field", "geometric langlands conjecture", "jongs conjecture says", "smooth projective curve", "order prime" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2004math......2184G" } } }
