A note on -axially symmetric harmonic maps from to minimizing the relaxed energy

arXiv:1011.5440 · doi:10.1016/j.jfa.2011.07.022

Abstract

For any n>1 we give an explicit example of an n-axially symmetric Cartesian current in B^3 x S^2 with non-trivial vertical part and non-constant graph part minimizing the relaxed Dirichlet energy among the n-axially symmetric Cartesian currents with the same boundary. This stands in sharp contrast with a results of Hardt, Lin and Poon for the case n=1.
