Nous démontrons que les K-surfaces abéliennes dont l'algèbre d'endomorphismes est une algèbre de quaternions sont paramétrisées, à isogénie près, par les points K-rationnels du quotient de certaines courbes de Shimura par le groupe de leurs involutions d'Atkin–Lehner.
We prove that the Abelian K-surfaces whose endomorphism algebra is a rational quaternion algebra are parametrized, up to isogeny, by the K-rational points of the quotient of certain Shimura curves by the group of their Atkin–Lehner involutions.
