Ahmed Mohammed Cherif: On the nonexistence of harmonic and bi-harmonic maps, 173-184

Abstract:

In this paper, we study the existence of harmonic and bi-harmonic maps into Riemannian manifolds admitting a conformal vector field, or a nontrivial Ricci solitons.

Key Words: Harmonic maps, bi-harmonic maps, Ricci solitons, conformal vector fields.
