The space of foliations on projective spaces in positive characteristic

Abstract

This work explores the space of foliations on projective spaces over algebraically closed fields of positive characteristic, with a particular focus on the codimension one case. It describes how the irreducible components of these spaces vary with the characteristic of the base field in very low degrees, and establishes an arbitrary characteristic version of Calvo-Andrade’s stability of generic logarithmic $1$-forms under deformation.
