Conformal and Harmonic Measures on Laminations Associated with Rational Maps
The framework of aane and hyperbolic laminations provides a unifying foundation for many aspects of conformal dynamics and hyperbolic geometry. The central objects of this approach are an aane Riemann surface lamination A and the associated hyperbolic 3-lamination H endowed with an action of a discrete group of iso-morphisms. This action is properly discontinuous on H, which allows one to pass ...
متن کاملA geometric theory of harmonic and semi-conformal maps
We describe for any Riemannian manifold M a certain scheme ML, lying in between the first and second neighbourhood of the diagonal of M . Semiconformal maps between Riemannian manifolds are then analyzed as those maps that preserve ML; harmonic maps are analyzed as those that preserve the (LeviCivita-) mirror image formation inside ML. Introduction For any Riemannian manifold M , we describe a ...
متن کاملHarmonicity of Horizontally Conformal Maps and Spectrum of the Laplacian
We discuss the harmonicity of horizontally conformal maps and their relations with the spectrum of the Laplacian. We prove that if φ : M → N is a horizontally conformal map such that the tension field is divergence free, then φ is harmonic. Furthermore, if N is noncompact, then φ must be constant. Also we show that the projection of a warped product manifold onto the first component is harmonic...
متن کاملHarmonic Maps and Biharmonic Maps
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.
متن کاملConformal Actions and Harmonic Morphisms
We give necessary and suucient conditions for a conformal foliation locally generated by conformal vector elds to produce harmonic morphisms. Natural constructions of harmonic maps and morphisms are thus obtained. Also we obtain reducibility results for harmonic morphisms induced by (innnitesimal) conformal actions on Einstein manifolds.
