Disproof of modularity of moduli space of CY 3-folds of double covers of P3 ramified along eight planes in general positions
Ralf Gerkmann, Sheng Mao, Kang Zuo
We prove that the moduli space of Calabi-Yau 3-folds coming from eight planes of in general positions is not modular. In fact we show the stronger statement that the Zariski…
