An Improved Energy-Area Inequality for Harmonic Maps Using Image Curvature

Differential Geometry 2009-09-29 v3 Classical Analysis and ODEs

Abstract

An ODE variational calculation shows that an image principle curvature ratio factor can raise the lower bound, 2(Image Area), on energy of a harmonic map of a surface into Rn. In certain situations, including all radially symmetry harmonic maps, equality is achieved.
