Some Results Involving Geodesic Curvature

  • The geodesic curvature is no other than the usual curvature of the curve when computed intrinsically in the submanifold . It does not depend on the way the submanifold sits in .
  • On the contrary the normal curvature depends strongly on how the submanifold lies in the ambient space, but marginally on the curve: only depends on the point on the submanifold and the direction, but not on .
  • In general Riemannian geometry the derivative will be computed using the Levi-Civita connection of the ambient manifold. It splits into a tangent part and a normal part to the submanifold:, and the tangent part is then the usual derivative in (see Gauss equation in the Gauss-Codazzi equations).
  • The Gauss–Bonnet theorem.

    “The restlessness that comes upon girls upon summer evenings results in lasting trouble unless it is speedily controlled. The right kind of man does not look for a wife on the streets, and the right kind of girl waits till the man comes to her home for her.”
    —Sedalia Times (1900)

    “Living is like working out a long addition sum, and if you make a mistake in the first two totals you will never find the right answer. It means involving oneself in a complicated chain of circumstances.”
    —Cesare Pavese (1908–1950)
