This wonderfully written book tells of the first Herculean expeditions to Antarctica, from astronomer Edmond Halley's 1699 voyage in the Paramore to the sealer John Balleny's 1839 excursion in the Eliza Scott, all in search of land, glory, fur, science, and profit. Life was harsh: crews had poor provisions and inadequate clothing, and scurvy was a constant threat. With unreliable--often homemade--charts, these intrepid explorers sailed in the stormy waters of the Southern Ocean below the Convergence, that sea frontier marking the boundary between the freezing Antarctic waters and the warmer sub-Antarctic seas. These men were the first to discover and exploit a new continent, which was not the verdant southern island they had imagined but an inhospitable expanse of rock and ice, ringed by pack ice and icebergs: Antarctica.

The next adventure in the High Republic begins expanding the new era of Star Wars, with a story set generations before Light of the Jedi. It is an age of exploration. Jedi travel the galaxy, expanding their understanding of the Force and all the worlds and beings connected by it. Meanwhile, the Republic, led by its two chancellors, works to unite worlds in an ever-growing community among near and distant stars. On the close-orbiting planets of Eiram and E’ronoh, the growing pains of a galaxy with limited resources but unlimited ambition are felt keenly. The two worlds’ hatred for each other has fueled half a decade of escalating conflict and now threatens to consume surrounding systems. The last hope for peace emerges when heirs from the planets’ royal families plan to marry. Before lasting peace can be established, an assassination attempt targeting the couple tilts Eiram and E’ronoh back into all-out war. To save both worlds, Jedi Knight Gella Nattai volunteers to uncover the culprit, while Chancellor Kyong appoints her own son, Axel Greylark, to represent the Republic’s interests in the investigation. But Axel’s deep distrust of the Jedi sparks against Gella’s faith in the Force. She’s never met such a puffed-up, privileged party boy, and he’s never met a more self-serious, relentless do-gooder. The harder they work to untangle the shadowy web of the investigation, the more complicated the conspiracy appears to be. With accusations flying and potential enemies in every shadow, the pair will have to work together to have any hope of bringing the truth to light and saving both worlds.

"Homotopy Analysis Method in Nonlinear Differential Equations" presents the latest developments and applications of the analytic approximation method for highly nonlinear problems, namely the homotopy analysis method (HAM). Unlike perturbation methods, the HAM has nothing to do with small/large physical parameters. In addition, it provides great freedom to choose the equation-type of linear sub-problems and the base functions of a solution. Above all, it provides a convenient way to guarantee the convergence of a solution. This book consists of three parts. Part I provides its basic ideas and theoretical development. Part II presents the HAM-based Mathematica package BVPh 1.0 for nonlinear boundary-value problems and its applications. Part III shows the validity of the HAM for nonlinear PDEs, such as the American put option and resonance criterion of nonlinear travelling waves. New solutions to a number of nonlinear problems are presented, illustrating the originality of the HAM. Mathematica codes are freely available online to make it easy for readers to understand and use the HAM. This book is suitable for researchers and postgraduates in applied mathematics, physics, nonlinear mechanics, finance and engineering. Dr. Shijun Liao, a distinguished professor of Shanghai Jiao Tong University, is a pioneer of the HAM.

The book deals with several closely related topics concerning approxima tions and perturbations of random processes and their applications to some important and fascinating classes of problems in the analysis and design of stochastic control systems and nonlinear filters. The basic mathematical methods which are used and developed are those of the theory of weak con vergence. The techniques are quite powerful for getting weak convergence or functional limit theorems for broad classes of problems and many of the techniques are new. The original need for some of the techniques which are developed here arose in connection with our study of the particular applica tions in this book, and related problems of approximation in control theory, but it will be clear that they have numerous applications elsewhere in weak convergence and process approximation theory. The book is a continuation of the author's long term interest in problems of the approximation of stochastic processes and its applications to problems arising in control and communication theory and related areas. In fact, the techniques used here can be fruitfully applied to many other areas. The basic random processes of interest can be described by solutions to either (multiple time scale) Ito differential equations driven by wide band or state dependent wide band noise or which are singularly perturbed. They might be controlled or not, and their state values might be fully observable or not (e. g. , as in the nonlinear filtering problem).

Price divergence is readily apparent to anyone who shops. Travelers from Manchester to London, or from Chicago to Paris, are hit by sticker shock. Products ranging from London Fog raincoats to Viagra are available over the Internet at half their retail store prices. Common experience tells us that prices for identical products differ between countries, between cities, even between neighboring shops. On the other hand, common experience also tells us that open markets and greater competition will force a degree of price convergence, if not identical prices. This monograph presents speculative calculations that illustrate potential benefits from price convergence between countries. The authors take a fresh look at global economic integration by examining existing price divergence, and possible price convergence, across a range of consumer goods and then calculate the potential benefits of price convergence on a country-by-country basis and for the world as a whole. This study examines the potential benefits from price convergence resulting from more competition and market integration, not perfect competition and market integration. The authors calculate these benefits assuming that the world economy can attain the same degree of competition and market integration—and hence price convergence—as exists within the United States.

While the stability theory for systems with bilateral constraints is a well-established field, this monograph represents a systematic study of mechanical systems with unilateral constraints, such as unilateral contact, impact and friction. Such unilateral constraints give rise to non-smooth dynamical models for which stability theory is developed in this work. The book will be of interest to those working in the field of non-smooth mechanics and dynamics.
