We generalize the notions of transversally harmonic maps between foliated Riemannian manifolds into transversally biharmonic maps. We show that a transversally biharmonic map into a foliated manifold of non-positive transverse curvature is transversally harmonic. ...
We generalize wave maps to exponential wave maps. We compute the first and second variations of the exponential energy, and obtain results concerning the stability of exponential wave maps. We prove a theorem which relates wave maps, exponential wave ...
We generalize biharmonic maps between Riemannian manifolds into the case of the domain being V-manifolds. We obtain the first and second variations of biharmonic maps on V-manifolds. Since a biharmonic map from a compact V-manifold into a Riemannian ...
In this article we discuss the spectral geometry of V-manifolds and its application to harmonic maps which generalize the spectral geometry of Riemannian manifolds and the theory of harmonic maps of Riemannian manifolds which was established by J. Eells and ...
The purpose of this paper is to generalize the theory of harmonic maps of riemannian manifolds which was established by J. Eells and JH Sampson [ES] to the case of V-manifolds (due to Satake [Sat 1, 2]). Let M, N be two compact smooth riemannian manifolds of dimension n, r with ...
