Abstract
In this paper we study projective flat deformations of ℙ n . We prove that the singular fibers of a projective flat deformation of ℙ n appear either in codimension 1 or over singular points of the base. We also describe projective flat deformations of ℙ n with smooth total space, and discuss flatness criteria.
