    A remark on a finiteness conjecture on mod \(p\) Galois representations by C. Khare (English)

    Let \(p\) be a prime number, \(F\) the algebraic closure of the field with \(p\) elements, \(K\) a number field, \(n\) a natural number, \(I\) an ideal in \({\mathcal O}_K\). If for every number field \(L\) there are only finitely many equivalence classes of semisimple continuous representations of Gal\((\overline {L} / L)\) on \(F\)-vector spaces of dimension \(\leq n\) that are unramified outside \(p\), then there are only finitely many equivalence classes of continuous semisimple representations of Gal\((\overline{K} / K)\) on \(F\)-vector spaces of dimension \(\leq n\) whose prime-to-\(p\) conductor is bounded by \(I\). This implication (and the finiteness statement itself, which remains unproven) has been conjectured by \textit{C. Khare} [J. Ramanujan Math. Soc. 15, 23-42 (2000; Zbl 1017.11028)].
