Abstract
Let \( \mathbb {P}^n \) be the projective space over an algebraically closed ground field K. In a previous paper, we have shown that the space of foliations by curves of degree greater than or equal to two which are uniquely determined by a subscheme of minimal degree of its scheme of singularities, contains a nonempty Zariski-open subset and hence, that the set of non-degenerate foliations with this property contains a Zariski-open subset. Moreover, we posed the question whether every non-degenerate foliation in \( \mathbb {P}^2 \) has this property. In this paper, we prove that this is true, in \( \mathbb {P}^2 \), in degrees 4 and 5.
