Abstract
Let be a polynomial skew product which leaves invariant an attracting vertical line . Assume moreover restricted to is non-uniformly hyperbolic, in the sense that restricted to satisfies one of the following conditions: 1. satisfies Topological Collet-Eckmann and Weak Regularity conditions. 2. The Lyapunov exponent at every critical value point lying in the Julia set of exist and is positive, and there is no parabolic cycle. Under one of the above conditions we show that the Fatou set in the basin of coincides with the union of the basins of attracting cycles, and the Julia set in the basin of has Lebesgue measure zero. As an easy consequence there are no wandering Fatou components in the basin of .
