note = {In this article we study nonsingular rational open surfaces of logarithmic Kodaira dimension zero with connected boundaries at infinity defined over an algebraically closed field of arbitrary characteristic. We establish a classification theory of nonsingular a½ne surfaces of logarithmic Kodaira dimension zero and give a characterization of A1 × A1 in arbitrary characteristic.},
