Universally irreducible subvarieties of Siegel moduli spaces
Gabriele Mondello, Riccardo Salvati Manni
A subvariety of a quasi-projective complex variety is called ``universally irreducible'' if its preimage inside the universal cover of is irreducible. In this paper we inve…
On Frobenius' theta formula
Alessio Fiorentino, Riccardo Salvati Manni
Mumford's well-known characterization of the hyperelliptic locus of the moduli space of ppavs in terms of vanishing and non-vanishing theta constants is based on Neumann's dynamica…
2-torsion points on theta divisors
Giuseppe Pareschi, Riccardo Salvati Manni
In this note we prove a sharp bound for the number of 2-torsion points on a theta divisor and show that this is achieved only in the case of products of elliptic curves. This settl…
The vanishing of two-point functions for three-loop superstring scattering amplitudes
Samuel Grushevsky, Riccardo Salvati Manni
In this paper we show that the two-point function for the three-loop chiral superstring measure ansatz proposed by Cacciatori, Dalla Piazza, and van Geemen vanishes. Our proof uses…
