Variétés abéliennes et invariants arithmétiques

We define here an analogue, for the Néron model of a semi-stable abelian variety defined over a number field, of M. J. Taylor's class-invariant homomorphism (defined for abelian schemes). Then we extend an annulation result (in the case of an elliptic curve), and an injectivity result regarding an arakelovian version of this homomorphism. This is the sequel to the paper "Invariants de classes : le cas semi-stable"
