Abstract: We recall the transcendance property of Painleve equations, the point of view of Casale in terms of Malgrange's Galois groupoid, and investigate a variation of it, related to neighborhoods of rational curves. In this direction, I will explain some result recently obtained in collaboration with Maycol Falla Luza, and some perspectives.
