Codimension one foliations of degree three on projective spaces

Abstract

We establish a structure theorem for degree three codimension one foliations on projective spaces of dimension n3n\ge 3, extending a result by Loray, Pereira, and Touzet for degree three foliations on P3\mathbb P^3. We show that the space of codimension one foliations of degree three on Pn\mathbb{P}^n, n3n\ge 3, has exactly 1818 distinct irreducible components parameterizing foliations without rational first integrals, and at least 66 distinct irreducible components parameterizing foliations with rational first integrals.
