On non-Kupka points of codimension one foliations on ${\mathbb{P}}^3$

O. Calvo-Andrade, M. Corrêa, A. Fernández-Pérez

We study the singular set of a codimension one holomorphic foliations on ${\mathbb{P}}^3$. We find a local normal form of a codimension two component of the singular set that is not…
