Abstract
AbstractA smooth affine surface X defined over the complex field C is an ML0 surface if the Makar– Limanov invariant ML(X) is trivial. In this paper we study the topology and geometry of ML0 surfaces. Of particular interest is the question: Is every curve C in X which is isomorphic to the affine line a fiber component of an A1-fibration on X? We shall show that the answer is affirmative if the Picard number ρ(X) = 0, but negative in case ρ(X) ≥ 1. We shall also study the ascent and descent of the ML0 property under proper maps.
