Tonoli's Calabi--Yau threefolds revisited

Grzegorz Kapustka, Michal Kapustka

Published 2013-10-02, updated 2015-05-29Version 5

We find a simple geometric construction of Tonoli's examples of Calabi--Yau threefolds of degree 17 in complex $\mathbb{P}^6$. We prove that the rank of the Picard group of elements of one of these families is at least $2$.
