Research output: Contribution to journalArticlepeer-review


Let α be a C curve in a homogeneous space G/H. For each point x on the curve, we consider the subspace Skα of the Lie algebra G of G consisting of the vectors generating a one parameter subgroup whose orbit through x has contact of order k with α. In this paper, we give various important properties of the sequence of subspaces G ⊃ S1α ⊃ S2α ⊃ S3α. In particular, we give a stabilization property for certain well-behaved curves. We also describe its relationship to the isotropy subgroup with respect to the contact element of order k associated with α.
