[1206.5229] Specialized Orthonormal Frames and Embedding

Authors: Frank B. Estabrook

Date: 22 Jun 2012

Abstract: We discuss specializations of the frames of flat orthonormal frame bundles over geometries of indefinite signature, and the resulting symmetries of families of imbedded Riemannian geometries; the embedding can be isometric, as in minimal surfaces or Regge-Teitelboim gravity, or torsion-free, as in Einstein vacuum gravity. Involutive Exterior Differential Systems (EDS) are given to express the well-posedness of the underlying partial differential embedding and specialization equations.
