An example of a non-algebraizable singularity

Abstract

We say that the the germ of a singular holomorphic foliation on $({\mathbb{C}}^2,0)$ is algebraizable whenever it is holomorphically conjugate to the singularity of a foliation defined globally on a projective algebraic surface. The object of this work is to construct a concrete example of a non--algebraizable singularity. Previously only existential results were known.
