Geodesic Flow on the Normal Congruence of a Minimal Surface

Abstract

Abstract. We study the geodesic flow on the normal line congruence of a minimal surface in R 3 induced by the neutral Kähler metric on the space of oriented lines. The metric is lorentz with isolated degenerate points and the flow is shown to be completely integrable. In addition, we give a new holomorphic description of minimal surfaces in R 3 and relate it to the classical Weierstrass representation.
