Harmonic functions, central quadrics, and twistor theory
نویسنده
چکیده
Solutions to the n-dimensional Laplace equation which are constant on a central quadric are found. The associated twistor description of the case n = 3 is used to characterise Gibbons-Hawking metrics with tri-holomorphic SL(2,C) symmetry.

Twistor Theory
Twistor theory began with the work of Roger Penrose who introduced the powerful techniques of complex algebraic geometry into general relativity. Loosely speaking it is the use of complex analytic methods to solve problems in real differential geometry. In most cases the emphasis is on the geometry of the problem rather than the analysis. My lectures are not designed to be a survey of all of tw...
متن کاملSurfaces in Four-dimensional Hyperkähler Manifolds Whose Twistor Lifts Are Harmonic Sections
We determine surfaces of genus zero in self-dual Einstein manifolds whose twistor lifts are harmonic sections. We apply our main theorem to the case of four-dimensional hyperkähler manifolds. As a corollary, we prove that a surface of genus zero in four-dimensional Euclidean space is twistor holomorphic if its twistor lift is a harmonic section. In particular, if the mean curvature vector field...
متن کاملFrédéric Hélein and
The subject of harmonic maps is vast and has found many applications, and it would require a very long book to cover all aspects, even superficially. Hence, we have made a choice; in particular, highlighting the key questions of existence, uniqueness and regularity of harmonic maps between given manifolds. Thus we shall survey some of the main methods of global analysis for answering these ques...
متن کاملComplexification, Twistor Theory, and Harmonic Maps from Riemann Surfaces
Penrose's twistor theory and many other ideas of mathematical physics are based on the notion of complexification. This notion is explained and examples of its apphcation in physics and mathematics are described. In particular, the well-known analogy between Yang-Mills fields and harmonic maps of Riemann surfaces becomes rather stronger after complexification. This strengthening is the main poi...
متن کاملHarmonic Morphisms between Riemannian Manifolds
Harmonic morphisms are mappings between Riemannian manifolds which preserve Laplace’s equation. They can be characterized as harmonic maps which enjoy an extra property called horizontal weak conformality or semiconformality. We shall give a brief survey of the theory concentrating on (i) twistor methods, (ii) harmonic morphisms with one-dimensional fibres; in particular we shall outline the co...
