In "Exterior Differential Systems", the authors present the results of their ongoing development of a theory of the geometry of differential equations, focusing especially on Lagrangians and Poincare-Cartan forms. They also cover certain aspects of the theory of exterior differential systems, which provides the language and techniques for the entire study, because it plays a central role in uncovering geometric properties of differential equations, the method of equivalence is particularly emphasized. In addition, the authors discuss conformally invariant systems at length, including results on the classification and application of symmetries and conservation laws. The book also covers the Second Variation, Euler-Lagrange PDE systems, and higher-order conservation laws. This synthesis of partial differential equations and differential geometry should be of fundamental importance to both students and experienced researchers working in geometric analysis - a subject that has been central in mathematics worldwide for the last 30 years.

An updated version of the bestselling, Game Testing All In One 3/E, this fourth edition serves as your comprehensive handbook to video game testing, guiding you through the essential skills needed to succeed in this exciting field. Whether you are a student seeking to enter the video game industry or a working professional aiming to refine your skills, this new edition gives you the basics skills of testing, demonstrates how game testing and testers fit into the game development process, and includes practical knowledge of tools, roles, responsibilities, and the metrics used to determine game quality and test progress. The reader is taken step-by-step through test design and other QA methods, using real game situations, and featuring interviews with veteran game developers. The book includes companion files for downloading with templates and tutorials for creating both combinatorial tables and test flow diagrams, which form the basis of a robust video game QA plan. Each chapter includes questions and exercises, making the book suitable for classroom use as well as a personal study or reference tool.

An updated version of the bestselling Game Testing All In One, this third edition equips the reader with the rationale for vigorous testing of game software, how game testing and the tester fit into the game development process, practical knowledge of tools to apply to game testing, game tester roles and responsibilities, and the measurements to determine game quality and testing progress. The reader is taken step-by-step through test design and other QA methods, using real game situations. The book includes content for the latest console games and the new crop of touch, mobile, and social games that have recently emerged. A companion DVD contains the tools used for the examples in the book and additional resources such as test table templates and generic flow diagrams to get started quickly with any game test project.
