Generalised Umbilics on Embedded Spheres
Published online by Cambridge University Press: 20 November 2018
Abstract
We study two kinds of generalized umbilics on smoothly embedded n-manifolds in ℝn+1. A sectional umbilic occurs where two of the principal curvatures are equal, and a split sectional umbilic is a more general notion.
