    Y is a harmonic map relative to Riemannian metrics g and h, and if e(X)+Id~e(Y)l >0, then ~p is holomorphic relative to the complex structures determined by g and h. Here e (X) = 2 - 2p and e (Y) = 2 - 2q denote Euler characteristics; and d, is the degree of cp. cp is holomorphic means that cp is either holomorphic or by: This book is concerned with harmonic maps into homogeneous spaces and focuses upon maps of Riemann surfaces into flag manifolds, to bring results of 'twistor methods' for symmetric spaces into a unified framework by using the theory of compact .

    The harmonic map energy Definition of energy and area Given a sufficiently smooth map u: M! N between smooth closed Riemannian manifolds (M,g) and N =(N,G) of any dimension, we can define the harmonic map energy E(u)=E(u,g):= 1 2 Z M |du|2 gdµ g. Smooth critical points are known as harmonic maps. By this, we mean that u is a harmonic mapFile Size: KB. Zygmund's two volume books on trigonometric series are good, but I would tackle a few other books on harmonic analysis before going for it. It is quite complex in comparison to the other references and will not help much if you do not already have a foundation in harmonic.

    4. Quasi-Harmonic Maps In order to motivate the ensuing discussion, we start with the following simple problem: Given a single triangle of a surface mesh and a map gthat carries the triangle into a cor-responding triangle in the planar domain. Solely from the properties of the map g, we can establish a second map fFile Size: 3MB. HARMONIC MAPPINGS OF RIEMANNIAN MANIFOLDS. 11 Chapter II. Deformations of maps. 6.

It introduces the necessary mathematical tools for the study of harmonic maps and presents applications of the methods and theory, bringing in results from recent research on the regularity of weak solutions.

The book will be of particular interest to graduate students and researchers in geometry, analysis and partial differential by: Harmonic maps are solutions to a natural geometrical variational prob­ lem.

This notion grew out of essential notions in differential geometry, such as geodesics, minimal surfaces and harmonic functions.

Harmonic maps are also closely related to holomorphic maps in several complex variables, to the. Harmonic maps are generalisations of the concept of geodesics.

They encompass many fundamental examples in differential geometry and have recently become of widespread use in many areas of mathematics and mathematical : Martin A. Guest. Harmonic maps between smooth Riemannian manifolds play a ubiquitous role in differential geometry.

Examples include geodesics viewed as maps, minimal surfaces, holomorphic maps and Abelian. Harmonic Maps Proceedings of the N.S.F.-C.B.M.S.

Harmonic Maps Book Subtitle Proceedings of the N.S.F.-C.B.M.S. Regional Conference, Held at Tulane. The book begins by introducing these concepts, stressing the interplay between geometry, the role of symmetries and weak solutions.

It then presents a guided tour into the theory of completely integrable systems for harmonic maps, followed by two chapters devoted to recent results on the regularity of weak solutions.

For example, the book excludes a large part of the theory of harmonic maps from 2-dimensional domains, where the methods are quite different from those discussed here. The first chapter consists of introductory material.

Several equivalent definitions of harmonic maps are described, and interesting examples are presented. harmonic maps. On the way, we mention harmonic morphisms: maps between Riemannian manifolds which pre-serve Laplace’s equation; these turn out to be a particular class of harmonic maps and exhibit some properties dual to those of harmonic maps.

More information on harmonic maps can be found in the following articles and books; for File Size: KB. Harmonic maps are the 'least expanding' maps in orthogonal directions. Existence of harmonic maps from a complete Riemannian manifold to a complete Riemannian manifold of non-positive sectional curvature was proved by Eells & Sampson ().

A harmonic map f: M → E m of a Riemann surface M is called a branched (or generalized) minimal immersion if it is conformal except at the branch points, and the image f(M) is called a branched minimal surface. Book Description. This book is concerned with harmonic maps into homogeneous spaces and focuses upon maps of Riemann surfaces into flag manifolds, to bring results of 'twistor methods' for symmetric spaces into a unified framework by using the theory of compact Lie groups and complex differential geometry.

The book can be used as a textbook for the topic course of advanced graduate students and for researchers who are interested in geometric partial differential equations and geometric analysis.

Wave maps are harmonic maps on Minkowski spaces and have been studied since the s. Yang-Mills fields, the critical points of Yang-Mills functionals of connections whose curvature tensors are harmonic, were explored by a few physicists in the s, and biharmonic maps (generalizing harmonic maps) were introduced by Guoying Jiang in   The monograph is by no means intended to give a complete description of the theory of harmonic maps.

Harmonic maps between Riemannian manifolds are solutions of systems of nonlinear partial differential equations which appear in different contexts of differential geometry.

They include holomorphic maps, minimal surfaces, σ-models in physics. This book presents these two reports in a single volume with a brief supplement reporting on some.

The aim of this book is to study harmonic maps, minimal and parallel mean curvature immersions in the presence of symmetry. In several instances, the latter permits reduction of the original elliptic variational problem to the qualitative study of certain ordinary differential equations: the authors’ primary objective is to provide representative examples to illustrate these.

Harmonic maps and the related theory of minimal surfaces are variational problems of long standing in differential geometry. Many important advances have been Harmonic Maps Into Homogeneous Spaces book. By Malcolm Black.
