Beltrami equation for the harmonic diffeomorphisms between surfaces

نویسندگان

چکیده

We study harmonic maps between surfaces, that are solutions to a nonlinear elliptic PDE. In Refs. Minsky (1992); Wolf (1989) it was proved diffeomorphisms, with nonvanishing Hopf differential, satisfy Beltrami equation of certain type: the imaginary part logarithm coefficient coincides differential. Therefore, is function. The real satisfies an differential equation, which in case constant curvature sinh-Gordon equation. this paper we also prove converse: if function, then target surface can be equipped metric, conformal original one, and solution map. solving equivalent map problem. Harmonic therefore classified by classification general problem still open. Different well-known hyperbolic plane related one-soliton Moreover, example proposed does not belong Solutions calculated for unified way, positive, negative zero surface.

Rotationally Symmetric Harmonic Diffeomorphisms between Surfaces

and Applied Analysis 3 We will prove this theorem by contradiction. The idea is similar to the proof of Theorem 1. Suppose ψ is a rotationally symmetric harmonic diffeomorphism from P(a) onto D∗ with the metric σ 2 d|u|, with the form ψ = g(r)e, then substituting ψ, σ 2 to u, σ in (2), respectively, we can get

PRELIMINARY VERSION Finite elements for the Laplace-Beltrami equation on parametric surfaces

In this paper we make a thorough study of the use of the finite element method to numerically compute harmonic maps from parametric surfaces to the plane. There are essentially two choices to be made in the FE method: (1) which elements and (2) which quadrature. We show that by using linear elements and point-based linear quadrature the method reduces to the cotangent method studied by Dziuk, P...

Covariantising the Beltrami equation in W-gravity

Recently, certain higher dimensional complex manifolds were obtained in [1] by associating a higher dimensional uniformisation to the generalised Teichmüller spaces of Hitchin. The extra dimensions are provided by the “times” of the generalised KdV hierarchy. In this paper, we complete the proof that these manifolds provide the analog of superspace for W-gravity and that Wsymmetry linearises on...

Harmonic Surface Mapping with Laplace-Beltrami Eigenmaps

In this paper we propose a novel approach for the mapping of 3D surfaces. With the Reeb graph of Laplace-Beltrami eigenmaps, our method automatically detects stable landmark features intrinsic to the surface geometry and use them as boundary conditions to compute harmonic maps to the unit sphere. The resulting maps are diffeomorphic, robust to natural pose variations, and establish corresponden...
