We produce new examples of harmonic maps, having as source manifold a space (M,g) of constant sectional curvature and as target manifold its tangent bundle TM, equipped with a suitable Riemannian g-natural metric. In particular, we determine a family of Riemannian g-natural metrics G on TS^2, with respect to which all conformal gradient vector fields define harmonic maps from S^2 into (TS^2,G), where S^2 denotes the unit sphere of dimension two.

Abstract
We produce new examples of harmonic maps, having as source manifold a space (M,g) of constant sectional curvature and as target manifold its tangent bundle TM, equipped with a suitable Riemannian g-natural metric. In particular, we determine a family of Riemannian g-natural metrics G on TS^2, with respect to which all conformal gradient vector fields define harmonic maps from S^2 into (TS^2,G), where S^2 denotes the unit sphere of dimension two.File in questo prodotto:
