Higher Ramanujan equations I: moduli stacks of abelian varieties and higher Ramanujan vector fields
We describe a higher dimensional generalization of Ramanujan's differential equations satisfied by the Eisenstein series $E_2$, $E_4$, and $E_6$. This will be obtained geometrically as follows. For every integer $g\ge 1$, we construct a moduli stack $\mathcal{B}_g$ over $\mathbf{Z}$ classifying...
