Monopoles and harmonic maps [PDF]

open access: yesJournal of Mathematical Physics, 1999
Recently Jarvis has proved a correspondence between SU(N) monopoles and rational maps of the Riemann sphere into flag manifolds. Furthermore, he has outlined a construction to obtain the monopole fields from the rational map. In this paper we examine this construction in some detail and provide explicit examples for spherically symmetric SU(N ...

Ricci flow coupled with harmonic map flow [PDF]

open access: yes, 2012
07.02.13 KB. Accepted version ok to add to Spiral. SMF/SherpaWe investigate a new geometric flow which consists of a coupled system of the Ricci flow on a closed manifold M with the harmonic map flow of a map phi from M to some closed target manifold N ...

Harmonic Gauss maps [PDF]

open access: yesPacific Journal of Mathematics, 1989
A construction is given whereby a Riemannian manifold induces a Riemannian metric on the total space of a large class of fibre bundles over it. Using this metric on the appropriate bundles, necessary and sufficient conditions are given for the Gauss map and the spherical Gauss map to be harmonic.

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_{\

2D Image Deformation Based on Guaranteed Feature Correspondence and Mesh Mapping

open access: yesIEEE Access, 2019
Image deformation has ubiquitous usage in multimedia applications. It morphs one image into another through a seamless transition. Existing techniques either mainly focus on the correspondence mapping of interior features of the objects in two images ...

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 ...

The generalized warped product and the biharmonic maps [PDF]

open access: yesArab Journal of Mathematical Sciences
PurposeIn the first, we consider a smooth map and we calculate the bitension field of the map as a consequence, we treat the biharmonicity of the second projection.

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.
