Low energy levels of harmonic spheres into analytic manifolds
We consider the energy spectrum ΞE(N) of harmonic maps from the sphere into a closed Riemannian manifold N. While a well known conjecture asserts that ΞE(N) is discrete whenever N is analytic, for most analytic targets it is only known that any potential accumulation point of the energy spectrum mus...
