tt*-geometry and pluriharmonic maps
Résumé
In this paper we use the real differential geometric definition of a metric (an unimodular oriented metric) tt*-bundle of Cortés and the author to define a map $\Phi$ from the space of metric (unimodular oriented metric) tt*-bundles of rank r over a complex manifold M to the space of pluriharmonic maps from M to $GL(r)/O(p,q)$ (respectively $SL(r)/SO(p,q)$), where (p,q) is the signature of the metric. In the sequel the image of the map $\Phi$ is characterized. It follows, that in signature (r,0) the image of $\Phi.$ is the whole space of pluriharmonic maps. This generalizes a result of Dubrovin.
