Univalent harmonic mappings [PDF]

open access: yesCommunications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1996
Summary: A family of univalent harmonic functions is studied from the point of geometric function theory. This class consists of mappings of the open unit disk onto the entire complex plane except for two infinite slits along the real axis with a normalization at the origin.

On Harmonic Quasiconformal Quasi-Isometries

open access: yesJournal of Inequalities and Applications, 2010
The purpose of this paper is to explore conditions which guarantee Lipschitz-continuity of harmonic maps with respect to quasihyperbolic metrics. For instance, we prove that harmonic quasiconformal maps are Lipschitz with respect to quasihyperbolic ...

A family of examples of harmonic maps into the sphere with one point singularity

open access: yesExamples and Counterexamples, 2023
The radial map u(x)=x‖x‖is a well-known example of a harmonic map into the spheres with a point singularity at x=0. In our previous paper (Misawa and Nakauchi, 2022) we give two examples of harmonic maps into the standard spheres of higher dimension with

Limits of $\alpha$-harmonic maps [PDF]

open access: yesJournal of Differential Geometry, 2020
Critical points of approximations of the Dirichlet energy \`{a} la Sacks-Uhlenbeck are known to converge to harmonic maps in a suitable sense. However, we show that not every harmonic map can be approximated by critical points of such perturbed energies. Indeed, we prove that constant maps and the rotations of $S^2$ are the only critical points of $E_{\

Convergence of Harmonic Maps [PDF]

open access: yesThe Journal of Geometric Analysis, 2015
In this paper we prove a compactness theorem for a sequence of harmonic maps which are defined on a converging sequence of Riemannian manifolds.

Harmonic Mappings of Spheres [PDF]

open access: yesAmerican Journal of Mathematics, 1972
This thesis is addressed to the following fundamental problem: given a homotopy class of maps between compact Riemannian manifolds N and M, is there a harmonic representative of that class? Eells and Sampson have given a general existence theorem for the case that M has no positive sectional curvatures [ESJ.\ud Otherwise, very little is known ...

Harmonic Maps and Biharmonic Maps [PDF]

open access: yesSymmetry, 2015
This is a survey on harmonic maps and biharmonic maps into (1) Riemannian manifolds of non-positive curvature, (2) compact Lie groups or (3) compact symmetric spaces, based mainly on my recent works on these topics.

Harmonic Maps on Kenmotsu Manifolds

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
We study in this paper harmonic maps and harmonic morphisms on Kenmotsu manifolds. We also give some results on the spectral theory of a harmonic map for which the target manifold is a Kenmotsu manifold.

On the Generalized of p-harmonic Maps

open access: yesInternational Electronic Journal of Geometry, 2022
In this paper, we extend the definition of p-harmonic and p-biharmonic maps between Riemannian manifolds. We present some new properties for the generalized stable p-harmonic maps.

Biharmonic maps on V-manifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
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.
