Invariant curves and analytic integrability of a planar vector field

We give an expression of the irreducible invariant curves at the singular point. For analytically integrable systems, we give a reduced expression of its  rst integral. This fact allows us to obtain necessary conditions of analytic integrability at degenerate singular points.
