摘要：
We characterize Siegel cusp forms in the space of Siegel modular forms of small weight on the congruence subgroups of any degree n and any level N, by a suitable growth of their Fourier coefficients (e.g., by the well known Hecke bound) at any one of the cusps. For this, we use the formalism of Jacobi forms and the 'Witt-operator' on modular forms.
