Download or read book Plateau s Problem written by Frederick J. Almgren (Jr.) and published by American Mathematical Soc.. This book was released on 1966 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been many wonderful developments in the theory of minimal surfaces and geometric measure theory in the past 25 to 30 years. Many of the researchers who have produced these excellent results were inspired by this little book - or by Fred Almgren himself. The book is indeed a delightful invitation to the world of variational geometry. A central topic is Plateau's Problem, which is concerned with surfaces that model the behavior of soap films.When trying to resolve the problem, however, one soon finds that smooth surfaces are insufficient: Varifolds are needed. With varifolds, one can obtain geometrically meaningful solutions without having to know in advance all their possible singularities. This new tool makes possible much exciting new analysis and many new results. Plateau's problem and varifolds live in the world of geometric measure theory, where differential geometry and measure theory combine to solve problems which have variational aspects. The author's hope in writing this book was to encourage young mathematicians to study this fascinating subject further. Judging from the success of his students, it achieves this exceedingly well.

Download or read book The Plateau written by Maggie Paxson and published by Penguin. This book was released on 2019-08-13 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the American Library in Paris Book Award Named a Best Book of 2019 by BookPage During World War II, French villagers offered safe harbor to countless strangers—mostly children—as they fled for their lives. The same place offers refuge to migrants today. Why? In a remote pocket of Nazi-held France, ordinary people risked their lives to rescue many hundreds of strangers, mostly Jewish children. Was this a fluke of history, or something more? Anthropologist Maggie Paxson, certainties shaken by years of studying strife, arrives on the Plateau to explore this phenomenon: What are the traits that make a group choose selflessness? In this beautiful, wind-blown place, Paxson discovers a tradition of offering refuge that dates back centuries. But it is the story of a distant relative that provides the beacon for which she has been searching. Restless and idealistic, Daniel Trocmé had found a life of meaning and purpose—or it found him—sheltering a group of children on the Plateau, until the Holocaust came for him, too. Paxson's journey into past and present turns up new answers, new questions, and a renewed faith in the possibilities for us all, in an age when global conflict has set millions adrift. Riveting, multilayered, and intensely personal, The Plateau is a deeply inspiring journey into the central conundrum of our time.

Download or read book On the Problem of Plateau Subharmonic Functions written by T. Rado and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: A convex function f may be called sublinear in the following sense; if a linear function l is ::=: j at the boundary points of an interval, then l:> j in the interior of that interval also. If we replace the terms interval and linear junction by the terms domain and harmonic function, we obtain a statement which expresses the characteristic property of subharmonic functions of two or more variables. This ge neralization, formulated and developed by F. RIEsz, immediately at tracted the attention of many mathematicians, both on account of its intrinsic interest and on account of the wide range of its applications. If f (z) is an analytic function of the complex variable z = x + i y. then If (z) I is subharmonic. The potential of a negative mass-distribu tion is subharmonic. In differential geometry, surfaces of negative curvature and minimal surfaces can be characterized in terms of sub harmonic functions. The idea of a subharmonic function leads to significant applications and interpretations in the fields just referred to, and· conversely, every one of these fields is an apparently in exhaustible source of new theorems on subharmonic functions, either by analogy or by direct implication.

Download or read book EPZ Thousand Plateaus written by Gilles Deleuze and published by A&C Black. This book was released on 2004-09-01 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: ‘A rare and remarkable book.' Times Literary Supplement Gilles Deleuze (1925-1995) was Professor of Philosophy at the University of Paris VIII. He is a key figure in poststructuralism, and one of the most influential philosophers of the twentieth century. Félix Guattari (1930-1992) was a psychoanalyst at the la Borde Clinic, as well as being a major social theorist and radical activist. A Thousand Plateaus is part of Deleuze and Guattari's landmark philosophical project, Capitalism and Schizophrenia - a project that still sets the terms of contemporary philosophical debate. A Thousand Plateaus provides a compelling analysis of social phenomena and offers fresh alternatives for thinking about philosophy and culture. Its radical perspective provides a toolbox for ‘nomadic thought' and has had a galvanizing influence on today's anti-capitalist movement. Translated by Brian Massumi>
Download or read book Plateau s Problem and the Calculus of Variations MN 35 written by Michael Struwe and published by Princeton University Press. This book was released on 2014-07-14 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is meant to give an account of recent developments in the theory of Plateau's problem for parametric minimal surfaces and surfaces of prescribed constant mean curvature ("H-surfaces") and its analytical framework. A comprehensive overview of the classical existence and regularity theory for disc-type minimal and H-surfaces is given and recent advances toward general structure theorems concerning the existence of multiple solutions are explored in full detail. The book focuses on the author's derivation of the Morse-inequalities and in particular the mountain-pass-lemma of Morse-Tompkins and Shiffman for minimal surfaces and the proof of the existence of large (unstable) H-surfaces (Rellich's conjecture) due to Brezis-Coron, Steffen, and the author. Many related results are covered as well. More than the geometric aspects of Plateau's problem (which have been exhaustively covered elsewhere), the author stresses the analytic side. The emphasis lies on the variational method. Originally published in 1989. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.

Download or read book Minimal Surfaces and Functions of Bounded Variation written by Giusti and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of finding minimal surfaces, i. e. of finding the surface of least area among those bounded by a given curve, was one of the first considered after the foundation of the calculus of variations, and is one which received a satis factory solution only in recent years. Called the problem of Plateau, after the blind physicist who did beautiful experiments with soap films and bubbles, it has resisted the efforts of many mathematicians for more than a century. It was only in the thirties that a solution was given to the problem of Plateau in 3-dimensional Euclidean space, with the papers of Douglas [DJ] and Rado [R T1, 2]. The methods of Douglas and Rado were developed and extended in 3-dimensions by several authors, but none of the results was shown to hold even for minimal hypersurfaces in higher dimension, let alone surfaces of higher dimension and codimension. It was not until thirty years later that the problem of Plateau was successfully attacked in its full generality, by several authors using measure-theoretic methods; in particular see De Giorgi [DG1, 2, 4, 5], Reifenberg [RE], Federer and Fleming [FF] and Almgren [AF1, 2]. Federer and Fleming defined a k-dimensional surface in IR" as a k-current, i. e. a continuous linear functional on k-forms. Their method is treated in full detail in the splendid book of Federer [FH 1].
Download or read book Minimal Submanifolds and Related Topics written by Xin Yuanlong and published by World Scientific. This book was released on 1989-05-01 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the theory of minimal submanifolds, Bernstein's problem and Plateau's problem are central topics. This important book presents the Douglas-Rado solution to Plateau's problem, but the main emphasis is on Bernstein's problem and its new developments in various directions: the value distribution of the Gauss image of a minimal surface in Euclidean 3-space, Simons' work for minimal graphic hypersurfaces, and the author's own contributions to Bernstein type theorems for higher codimension. The author also introduces some related topics, such as submanifolds with parallel mean curvature, Weierstrass type representation for surfaces of mean curvature 1 in hyperbolic 3-space, and special Lagrangian submanifolds. This new edition contains the author's recent work on the Lawson-Osserman's problem for higher codimension, and on Chern's problem for minimal hypersurfaces in the sphere. Both Chern's problem and Lawson-Osserman's problem are important problems in minimal surface theory which are still unsolved. In addition, some new techniques were developed to address those problems in detail, which are of interest in the field of geometric analysis.

This book was released on 2003 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusing myriad primary and secondary sources, historian Larry Cebula offers a compelling master narrative of the impact of Christianity on the Columbian Plateau peoples in the Pacific Northwest from 1700 to 1850. ø For the Native peoples of the Columbian Plateau, the arrival of whites was understood primarily as a spiritual event, calling for religious explanations. Between 1700 and 1806, Native peoples of the Columbian Plateau experienced the presence of whites indirectly through the arrival of horses, some trade goods by long-distance exchange, and epidemic diseases that decimated their population and shook their faith in their religious beliefs. Many responded by participating in the Prophet Dance movement to restore their frayed links to the spirit world. ø When whites arrived in the early nineteenth century, the Native peoples of the Columbian Plateau were more concerned with learning about white people's religious beliefs and spiritual power than with acquiring their trade goods; trading posts were seen as windows into another world rather than sources of goods. The whites? strange appearance and seeming immunity to disease and the unique qualities of their goods and technologies suggested great spiritual power to the Native peoples. But disillusionment awaited: Catholic and Protestant missionaries came to teach the Native peoples about Christianity, yet these white spiritual practices failed to protect them from a new round of epidemic disease. By 1850, with their world devastatingly altered, most Plateau Indians had rejected Christianity

Download or read book Restoration and Development of the Degraded Loess Plateau China written by Atsushi Tsunekawa and published by Springer Science & Business Media. This book was released on 2013-08-23 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents state-of-the-art scientific evidence and technological innovations to restore lands on the Loess Plateau of China, known worldwide for its serious land degradation and desertification problems. Supported by a rapidly developing Chinese economy and the dissemination of effective technology, the Grain-for-Green Project and Western Development Action launched by the Chinese government have resulted in successful ecological restoration and protection over the past 30 years. These programs have contributed not only to conservation of soil and water, but also to economic development. At the same time, however, these developmental interventions have brought new challenges that have not yet been fully addressed. The book describes (1) case studies of success and failure in practice, including rare success stories of combating desertification; (2) technical issues such as erosion control and breeding of stress-tolerant plant species, and socioeconomic measures taken by the Chinese government and lending policies with support from the World Bank; and (3) comprehensive measures against desertification, such as water and wind erosion, salinization, and deforestation. This volume is recommended for researchers and students above the undergraduate level in diverse fields including soil science, rural engineering, social technology and civil engineering, biology, ecology, climatology, physical and human geography, and developmental economics, among others. It also serves as a valuable resource for engineers, government officials, and NPOs and NGOs involved in afforestation, ecological restoration, combating desertification, disaster prevention, and sustainable rural development.
