We prove a generalization of the Castelnuovo-de Franchis theorem in the case of p-forms and we apply it to show when, under some natural conditions, a suitable subset of p-forms constructs the Iitaka fibration. © The Author(s), under exclusive licence to Springer-Verlag Italia S.r.l., part of Springer Nature 2024.
