Isotrivial Unfoldings and Structural Theorems for Foliations on Projective Spaces.

Following Suwa, we study unfoldings of algebraic foliations and their relationship with families of foliations, making focus on those unfoldings related to trivial families. The results obtained in the study of unfoldings are then applied to obtain information on the structure of foliations on projective spaces. [ABSTRACT FROM AUTHOR]
