Abstract:
Honda proved that two formal groups attached to an elliptic curve E over Q are strongly isomorphic over Z, where one of them is obtained from the formal completion along the zero section of the Néron model over Z and another is obtained from the L-series attached to the l-adic Galois representations on E. In this paper, we generalize his theorem to abelian varieties over Q of GL2-type. As an application, we give a method to calculate the coefficients of the L-series attached to an algebraic curve over Q with a Jacobian variety of GL2-type.
Keywords: Formal group, abelian variety of GL2-type, complex multiplication, L-series.
