Using the theory of b-divisors and non-pluripolar products we show that Chen-Weil theory and a Hilbert Samuel theorem can be extended to a wide class of singular semi-positive metrics. We then apply these results to study the line bundle of Siegel-Jacobi forms on the universal abelian variety with the Peterson metric. We show on the one hand that the ring of Siegel-Jacobi forms of constant positive relative index is never finitely generated, and on the other, we recover a formula of Tai giving the asymptotic growth of the dimension of the spaces of Siegel-Jacobi modular forms. This is joint work with J. Burgos Gil, R. de Jong and D. Holmes.
