Abstract. We consider a finite composition of generalized Hénon mappings f : C 2 → C 2 and its Green function g + : C 2 → R ≥0 (see Section 2). It is well known that each level set {g + = c} for c > 0 is foliated by biholomorphic images of C and each leaf is dense. In this paper, we prove that each leaf is actually an injective Brody curve in P 2 (see Section 4). We also study the behavior of the level sets of g + near infinity.
