KP Solitons and the Grassmannians

Author: Yuji Kodama
Publisher: Springer
ISBN: 9789811040948
Release Date: 2017-04-20
Genre: Science

This is the first book to treat combinatorial and geometric aspects of two-dimensional solitons. Based on recent research by the author and his collaborators, the book presents new developments focused on an interplay between the theory of solitons and the combinatorics of finite-dimensional Grassmannians, in particular, the totally nonnegative (TNN) parts of the Grassmannians. The book begins with a brief introduction to the theory of the Kadomtsev–Petviashvili (KP) equation and its soliton solutions, called the KP solitons. Owing to the nonlinearity in the KP equation, the KP solitons form very complex but interesting web-like patterns in two dimensions. These patterns are referred to as soliton graphs. The main aim of the book is to investigate the detailed structure of the soliton graphs and to classify these graphs. It turns out that the problem has an intimate connection with the study of the TNN part of the Grassmannians. The book also provides an elementary introduction to the recent development of the combinatorial aspect of the TNN Grassmannians and their parameterizations, which will be useful for solving the classification problem. This work appeals to readers interested in real algebraic geometry, combinatorics, and soliton theory of integrable systems. It can serve as a valuable reference for an expert, a textbook for a special topics graduate course, or a source for independent study projects for advanced upper-level undergraduates specializing in physics and mathematics.

Introduction to Singularities

Author: Shihoko Ishii
Publisher: Springer
ISBN: 9784431550815
Release Date: 2014-11-19
Genre: Mathematics

This book is an introduction to singularities for graduate students and researchers. It is said that algebraic geometry originated in the seventeenth century with the famous work Discours de la méthode pour bien conduire sa raison, et chercher la vérité dans les sciences by Descartes. In that book he introduced coordinates to the study of geometry. After its publication, research on algebraic varieties developed steadily. Many beautiful results emerged in mathematicians’ works. Most of them were about non-singular varieties. Singularities were considered “bad” objects that interfered with knowledge of the structure of an algebraic variety. In the past three decades, however, it has become clear that singularities are necessary for us to have a good description of the framework of varieties. For example, it is impossible to formulate minimal model theory for higher-dimensional cases without singularities. Another example is that the moduli spaces of varieties have natural compactification, the boundaries of which correspond to singular varieties. A remarkable fact is that the study of singularities is developing and people are beginning to see that singularities are interesting and can be handled by human beings. This book is a handy introduction to singularities for anyone interested in singularities. The focus is on an isolated singularity in an algebraic variety. After preparation of varieties, sheaves, and homological algebra, some known results about 2-dim ensional isolated singularities are introduced. Then a classification of higher-dimensional isolated singularities is shown according to plurigenera and the behavior of singularities under a deformation is studied.

Sex in China

Author: Fang Fu Ruan
Publisher: Springer Science & Business Media
ISBN: 9781489906090
Release Date: 2013-11-22
Genre: Medical

China today is sexually (and in many other ways) a very repressive so ciety, yet ancient China was very different. Some of the earliest surviving literature of China is devoted to discussions of sexual topics, and the sexual implications of the Ym and Yang theories common in ancient China continue to influence Tantric and esoteric sexual practices today far dis tant from their Chinese origins. In recent years, a number of books have been written exploring the history of sexual practices and ideas in China, but most have ended the discussion with ancient China and have not continued up to the present time. Fang Fu Ruan first surveys the ancient assumptions and beliefs, then carries the story to present-day China with brief descriptions of homosexuality, lesbianism, transvestism, transsexualism, and prostitution, and ends with a chapter on changing attitudes toward sex in China today. Dr. Ruan is well qualified to give such an overview. Until he left China in the 1980s, he was a leader in attempting to change the repressive attitudes of the government toward human sexuality. He wrote a best selling book on sex in China, and had written to and corresponded with a number of people in China who considered him as confidant and ad visor about their sex problems. A physician and medical historian, Dr. Ruan's doctoral dissertation was a study of the history of sex in China.

The central topic of this book is the presentation of the author's principle of arithmetical paraphrases, which won him the Bocher Prize in 1924. This general principle served to unify and extend many isolated results in the theory of numbers. The author successfully provides a systematic attempt to find a unified theory for each of various classes of related important problems in the theory of numbers, including its interrelations with algebra and analysis. This book will be of interest to advanced students in various branches of mathematics, including number theory, abstract algebra, elliptic and theta functions, Bernoulli numbers and functions, and the foundations of mathematics.

Design Thinking Research

Author: Hasso Plattner
Publisher: Springer
ISBN: 9783319068237
Release Date: 2014-07-16
Genre: Business & Economics

Design thinking as a user-centric innovation method has become more and more widespread during the past years. An increasing number of people and institutions have experienced its innovative power. While at the same time the demand has grown for a deep, evidence-based understanding of the way design thinking functions. This challenge is addressed by the Design Thinking Research Program between Stanford University, Palo Alto, USA and Hasso Plattner Institute, Potsdam, Germany. Summarizing the outcomes of the 5th program year, this book imparts the scientific findings gained by the researchers through their investigations, experiments and studies. The method of design thinking works when applied with diligence and insight. With this book and the underlying research projects, we aim to understand the innovation process of design thinking and the people behind it. The contributions ultimately center on the issue of building innovators. The focus of the investigation is on what people are doing and thinking when engaged in creative design innovation and how their innovation work can be supported. Therefore, within three topic areas, various frameworks, methodologies, mind sets, systems and tools are explored and further developed. The book begins with an assessment of crucial factors for innovators such as empathy and creativity, the second part addresses the improvement of team collaboration and finally we turn to specific tools and approaches which ensure information transfer during the design process. All in all, the contributions shed light and show deeper insights how to support the work of design teams in order to systematically and successfully develop innovations and design progressive solutions for tomorrow.

Exact Exponential Algorithms

Genre: Mathematics

For a long time computer scientists have distinguished between fast and slow algo rithms. Fast (or good) algorithms are the algorithms that run in polynomial time, which means that the number of steps required for the algorithm to solve a problem is bounded by some polynomial in the length of the input. All other algorithms are slow (or bad). The running time of slow algorithms is usually exponential. This book is about bad algorithms. There are several reasons why we are interested in exponential time algorithms. Most of us believe that there are many natural problems which cannot be solved by polynomial time algorithms. The most famous and oldest family of hard problems is the family of NP complete problems. Most likely there are no polynomial time al gorithms solving these hard problems and in the worst case scenario the exponential running time is unavoidable. Every combinatorial problem is solvable in ?nite time by enumerating all possi ble solutions, i. e. by brute force search. But is brute force search always unavoid able? De?nitely not. Already in the nineteen sixties and seventies it was known that some NP complete problems can be solved signi?cantly faster than by brute force search. Three classic examples are the following algorithms for the TRAVELLING SALESMAN problem, MAXIMUM INDEPENDENT SET, and COLORING.
