Weierstrass-type representation for harmonic maps into general symmetric spaces via loop groups
In  a method was presented, which constructs via loop group splittings all harmonic maps into a compact symmetric space. The present paper generalizes this method to all spaces , where is an arbitrary Lie group (semisimple or not) and is the fixpoint group of some involution of . The method is illustrated by a number of examples.
