Two examples of harmonic maps into spheres

The radial map w(x) = x ||x||(-1) is a well-known example of harmonic maps and p-harmonic ones into spheres with a point singularity. In this paper we give two examples of harmonic maps and p-harmonic ones into spheres of higher dimensions with the singularity x(i)x(j) ||x||(-2) or the singularity x(i)x(j)x(k) ||x||(-3).
