The book constitutes a basic, concise, yet rigorous course in complex analysis, for students who have studied calculus in one and several variables, but have not previously been exposed to complex analysis. The textbook should be particularly useful and relevant for undergraduate students in joint programmes with mathematics, as well as engineering students. The aim of the book is to cover the bare bones of the subject with minimal prerequisites. The core content of the book is the three main pillars of complex analysis: the Cauchy–Riemann equations, the Cauchy Integral Theorem, and Taylor and Laurent series expansions. Each section contains several problems, which are not purely drill exercises, but are rather meant to reinforce the fundamental concepts. Detailed solutions to all the exercises appear at the end of the book, making the book ideal also for self-study. There are many figures illustrating the text. Errata(s) Errata (72 KB)

Olympiad mathematics is not a collection of techniques of solving mathematical problems but a system for advancing mathematical education. This book is based on the lecture notes of the mathematical Olympiad training courses conducted by the author in Singapore. Its scope and depth not only covers and beyond the usual syllabus, but introduces a variety of concepts and methods in modern mathematics as well. In each lecture, the concepts, theories and methods are taken as the core. The examples serve to explain and enrich their intentions and to indicate their applications. Besides, appropriate number of test questions is available for the readers' practice and testing purpose. Their detailed solutions are also conveniently provided. The examples are not very complicated so readers can easily understand. There are many real competition questions included which students can use to verify their abilities. These test questions originate from many countries all over the world. This book will serve as a useful textbook of mathematical Olympiad courses, a self-study lecture notes for students, or as a reference book for related teachers and researchers.

What is the relationship between China and the international society? It is a question of historical and realistic significance for China and the world to answer. Since the reform and opening up, China initiated a journey to get integrated into the international society. As an emerging power, China is trying to seek identities, display strength, and build a good reputation. Under various determinants and possibilities, the relationship between China and the international society manifests a feature of complexity and multiple dimensions. Following a guideline of “on China, for the world”, this volume intends to introduce Chinese scholars' latest studies on China's global strategies, theories and policies to the outside world. Contents:The Self-Consciousness of Chinese-Characteristic Diplomatic Practice and Theory (Yang Jiemian)China and International System: Two-Way Socialization under the Logic of Practice (Zhu Liqun)An Analytical Study of the Ideological Sources of China's Conduct (Zhang Qingmin and Lee Min Gyu)Self-Generated Transformation: On China's Agency in Its Interaction with International Human Rights Norms (Chen Zheng)Border, Geopolitics and China's International Relations Study (Zheng Yongnian)Evolution of “Neighborhood” Concept and China's Foreign Strategies (Zhong Feiteng)The Role and Influence of China's Mainstream Media in South China Sea Disputes — An Analysis from the Perspective of Signaling (Liao Lei and Ma Mengli)Public Policy and Cross-Border Investment by Chinese Enterprises (Guo Hong)China's Approaches and Future Prospects for Participation in UN Peacekeeping and Peacebuilding: A Report Based on Field Research of UN Peacekeeping and Peacebuilding Missions in Africa (Li Dongyan)Origin of the Forum on China–Africa Cooperation (Li Anshan) Readership: Academics, professionals, undergraduate and graduate students interested in China's diplomatic practice and theory and China's international relations studies.

## The Story Of Numbers

This book is more than a mathematics textbook. It discusses various kinds of numbers and curious interconnections between them. Without getting into hardcore and difficult mathematical technicalities, the book lucidly introduces all kinds of numbers that mathematicians have created. Interesting anecdotes involving great mathematicians and their marvelous creations are included. The reader will get a glimpse of the thought process behind the invention of new mathematics. Starting from natural numbers, the book discusses integers, real numbers, imaginary and complex numbers and some special numbers like quaternions, dual numbers and p-adic numbers. Real numbers include rational, irrational and transcendental numbers. Iterations on real numbers are shown to throw up some unexpected behavior, which has given rise to the new science of "Chaos". Special numbers like e, pi, golden ratio, Euler's constant, Gauss's constant, amongst others, are discussed in great detail. The origin of imaginary numbers and the use of complex numbers constitute the next topic. It is shown why modern mathematics cannot even be imagined without imaginary numbers. Iterations on complex numbers are shown to generate a new mathematical object called 'Fractal', which is ubiquitous in nature. Finally, some very special numbers, not mentioned in the usual textbooks, and their applications, are introduced at an elementary level. The level of mathematics discussed in this book is easily accessible to young adults interested in mathematics, high school students, and adults having some interest in basic mathematics. The book concentrates more on the story than on rigorous mathematics.

This book primarily serves as a historical research monograph on the biographical sketch and career of Leonhard Euler and his major contributions to numerous areas in the mathematical and physical sciences. It contains fourteen chapters describing Euler''s works on number theory, algebra, geometry, trigonometry, differential and integral calculus, analysis, infinite series and infinite products, ordinary and elliptic integrals and special functions, ordinary and partial differential equations, calculus of variations, graph theory and topology, mechanics and ballistic research, elasticity and fluid mechanics, physics and astronomy, probability and statistics. The book is written to provide a definitive impression of Euler''s personal and professional life as well as of the range, power, and depth of his unique contributions. This tricentennial tribute commemorates Euler the great man and Euler the universal mathematician of all time. Based on the author''s historically motivated method of teaching, special attention is given to demonstrate that Euler''s work had served as the basis of research and developments of mathematical and physical sciences for the last 300 years. An attempt is also made to examine his research and its relation to current mathematics and science. Based on a series of Euler''s extraordinary contributions, the historical development of many different subjects of mathematical sciences is traced with a linking commentary so that it puts the reader at the forefront of current research.
