## Abstract

Let F = (P, Q) ∈ C[X, Y ] 2 be a polynomial mapping over the complex field C. Suppose that det JF (X, Y ) := ∂P ∂X ∂Q ∂Y − ∂P ∂Y ∂Q ∂X = a ∈ C ×. A mapping that satisfies the assumptions above is called a Keller mapping. In this paper we estimate the size of the co-image of F. We give a sufficient condition for surjectivity of Keller mappings in terms of its Phantom curve. This curve is closely related to the asymptotic variety

of F.
