Any unit vector field that is a harmonic map is also a harmonic vector field. The study of harmonic map system is more appropriate on a Hermitian manifold and that results in Hermitian harmonic maps to be useful in studying rigidity of complete Hermitian manifolds.

Harmonic vector fields aren't harmonic maps in general (a unit vector field X: M → S(M) is a harmonic map if and only if X is a harmonic vector field and the additional condition trace g {R(∇. X, X)⋅} = 0 is satisfied, cf. Corollary in Chapter 2 of this monograph or O. Gil-Medrano, []).

Abstract: A vector field s on a Riemannian manifold M is said to be harmonic if there exists a member of a 2-parameter family of generalised Cheeger-Gromoll metrics on TM with respect to which s is a harmonic section.

If M is a simply-connected non-flat space form other than the 2-sphere, examples are obtained of conformal vector fields that are harmonic. There is a whole book, Harmonic Vector Fields: Variational Principles and Differential Geometry, by S.

time-harmonic fields. In fact, it is possible to use many of the rules known from real vector algebra, although not all the conclusions. Properties of the ellipse of time-harmonic vectors can be seen to be directly obtainable through operations on complex vectors. Notation As mentioned above, complex vector formalism is applied in.

We find that a global approach is hampered by significant computational costs, and thus describe a local framework for harmonic vector field analysis to address this concern.Recall that on a Riemannian manifold (M, g), a unit vector field V is said to be a harmonic vector field if V: (M, g) → (T 1 M,G), whereG is the Sasaki metric (cf.
