Abstract

In this paper it is explained how one can construct non-selfdual 4-dimensional \ell-adic Galois representations of Hodge type h3,0=h2,1=h1,2=h0,3=1h^{3,0}=h^{2,1}=h^{1,2}=h^{0,3}=1, assuming a hypothesis concerning the cohomology of a certain threefold. For one such a representation the first 80000 coefficients of its LL-function are computed, and it is numerically verified that this LL-function satisfies a functional equation. Also a candidate for the conductor is obtained.
