Abstract

In this work we prove a Baum-Bott type formula for non-compact complex manifold of the form X~=XD\tilde{X}=X- \mathcal{D}, where XX is a complex compact manifold and D\mathcal{D} is a normal crossing divisor on XX. As applications, we provide a Poincar\'e-Hopf type Theorem and an optimal description for a smooth hypersurface D\mathcal{D} invariant by an one-dimensional foliation F\mathscr F on Pn\mathbb{P}^n satisfying Sing(F)D.Sing(\mathscr F) \subsetneq \mathcal{D}.
