A duality theorem for harmonic maps into inner symmetric spaces

Differential Geometry 2024-08-26 v2

Abstract

In this note, we show that for any harmonic map into a non-compact symmetric space one can find naturally a "dual" harmonic map into a compact symmetric space which can be constructed from the same basic data (called "potentials" in the loop group formalism). Locally also the inverse/converse duality theorem holds.
