A computational view on the non-degeneracy invariant for Enriques surfaces

Riccardo Moschetti, Franco Rota, Luca Schaffler

For an Enriques surface $S$, the non-degeneracy invariant $\mathrm{nd}(S)$ retains information on the elliptic fibrations of $S$ and its polarizations. In the current paper, we int…
