Abstract

Let F\mathscr{F} be a singular holomorphic foliation, of codimension kk, on a complex compact manifold such that its singular set has codimension k+1\geq k+1. In this work we determinate Baum-Bott residues for F\mathscr{F} with respect to homogeneous symmetric polynomials of degree k+1k+1. We drop the Baum-Bott's generic hypothesis and we show that the residues can be expressed in terms of the Grothendieck residue of an one-dimensional foliation on a (k+1)(k+1)-dimensional disc transversal to a (k+1)(k+1)-codimensional component of the singular set of F\mathscr{F}. Also, we show that Cenkl's algorithm for non-expected dimensional singularities holds dropping the Cenkl's regularity assumption.
