Topological characterization of C2 via open algebraic surface theory

Abstract

We will give a new proof of Ramanujam’s topological characterization of the affine [Formula: see text]-space [Formula: see text] using the Abhyankar–Moh–Suzuki theorem on embeddings of the affine line in [Formula: see text] and some ideas from the theory of open algebraic surfaces. </jats:p
