Equigeodesics on flag manifolds
arXiv:0904.3770
Abstract
This paper provides a characterization of homogeneous curves on a geometric flag manifold which are geodesic with respect to any invariant metric. We call such curves homogeneous equigeodesics. We also characterize homogeneous equigeodesics whose associated Killing field is closed, hence, the corresponding geodesics is closed.
New section about closed equigeodesics included. Misprints corrected
