Abstract:

We determine the structure of the graded ring of Siegel modular forms of degree 3. It is generated by 19 modular forms, among which we identify a homogeneous system of parameters with 7 forms of weights $4$, $12$, $12$, $14$, $18$, $20$ and $30$. We also give a complete dictionary between the Dixmier-Ohno invariants of ternary quartics and the above generators.
