Normal curvature of surfaces in space forms

Irwen Valle Guadalupe and Lucio Ladislao Rodriguez

Vol. 106 (1983), No. 1, 95–103
Abstract

Using the notion of the ellipse of curvature we study compact surfaces in high dimensional space forms. We obtain some inequalities relating the area of the surface and the integral of the square of the norm of the mean curvature vector with topological invariants. In certain cases, the ellipse is a circle; when this happens, restrictions on the Gaussian and normal curvatures give us some rigidity results.
