A solution of a problem of Sophus Lie: Normal forms of 2-dim metrics admitting two projective vector fields

Robert L. Bryant, Gianni Manno, Vladimir S. Matveev

Published 2007-05-24, updated 2007-08-07Version 2

We give a complete list of normal forms for the 2-dimensional metrics that admit a transitive Lie pseudogroup of geodesic-preserving transformations and we show that these normal forms are mutually non-isometric. This solves a problem posed by Sophus Lie.
