On Cox Rings of Calabi-Yau hypersurfaces
Michela Artebani, Antonio Laface, Luca Ugaglia
We study the Cox rings of smooth anticanonical Calabi-Yau hypersurfaces in smooth toric Fano varieties. Using the combinatorics of primitive pairs of the ambient Fano polytope and…

Calabi-Yau complete intersections associated to good pairs of generalized nef partitions
Michela Artebani, Paola Comparin, Robin Guilbot
We introduce the notion of good pair of generalized nef partitions to describe Calabi-Yau complete intersections in Q-Fano toric varieties whose equations do not necessarily have m…
