Resumo: The simplest harmonic maps from the two sphere into the unitary group are the isotropic ones. Using Morse theory, Burstall and Guest showed that the harmonic maps are partitioned into classes labeled by the isotropic ones. In this work, we describe explicitly this procedure, showing how all harmonic maps can be built from the isotropic ones.
