Doc. Math. (Bielefeld) Extra Vol. John H. Coates' Sixtieth Birthday, 729-779 (2006)
Summary
We prove that the L-function of any regular (distinct Hodge numbers), irreducible, rank two motive over the rational numbers has meromorphic continuation to the whole complex plane and satisfies the expected functional equation.
