ROTATIONALLY SYMMETRIC HARMONIC DIFFEOMORPHISMS IN PLANE

In this paper, we study that the existence of rotationally symmetric harmonic diffeomorphism between the punctured complex plane with hyperbolic metric or Euclidean metric.

A nonexistence result on harmonic diffeomorphisms between punctured spaces

Harmonic Diffeomorphisms between Complete Surfaces

We prove an existing theorem of homotopic harmonic diffeomorphisms between complete surfaces of finite total curvature and nontrivial genus. This is a generalization of a theorem of Jost and Schoen

Images of harmonic maps with symmetry

We show that under certain symmetry, the images of complete harmonic embeddings from the complex plane into the hyperbolic plane is completely determined by the geometric information of the vertical

On the Asymptotic Behavior of Rotationally Symmetrical Harmonic Maps

Abstract We study a second order ordinary differential equation which is the Euler-Lagrange equation of the energy functional for maps with prescribed rotational symmetry. We obtain Liouville′s type

Rotationally symmetric harmonic maps from a ball into a warped product manifold

This paper deals with the existence problem for rotationally symmetric harmonic maps from an Euclidean unit ball B ⊂ ℝn or ℝn into a warped product manifold Nf=[0, r0)xfSn−1.

Harmonic diffeomorphisms and Teichmüller theory

Teichmüller spaces of Riemann surfaces usually are treated by using quasi conformal mappings. We prove the existence of a harmonic diffeomorphism between punctured surfaces. We take this to build up

Harmonic diffeomorphisms of the hyperbolic plane

In this paper, we consider the Dirichlet problem at infinity for harmonic maps between the Poincare model D of the hyperbolic plane H2, and solve this when given boundary data are C4 immersions of

We prove a theorem for harmonic diffeomorphisms between the unit disc and a convex Jordan domain, which is a generalization of Heinz theorem [E. Heinz (1959). On one-to-one harmonic mappings. Pacific

New examples of harmonic diffeomorphisms of the hyperbolic plane onto itself

A one parameter family of new examples of harmonic maps of the hyperbolic plane onto itself is constructed by studying the Gauss map of certain spacelike constant mean curvature surfaces in three

Harmonic diffeomorphisms, minimizing harmonic maps and rotational symmetry

We study harmonic diffeomorphisms between BnB{a1, ... , ak} and a Riemannian manifold u. For n = 2 and k = 0, we prove that such diffeomorphisms are minimizing harmonic maps, we generalize this

Hopf Differentials and the Images of Harmonic Maps

Non-polynomial growth harmonic maps from the complex plane to the hyperbolic space are studied. Some non-surjectivity results are obtained. Moreover, images of such harmonic maps are investigated
