Sommario/riassunto |
|
Topological solitons occur in many nonlinear classical field theories. They are stable, particle-like objects, with finite mass and a smooth structure. Examples are monopoles and Skyrmions, Ginzburg-Landau vortices and sigma-model lumps, and Yang-Mills instantons. This book is a comprehensive survey of static topological solitons and their dynamical interactions. Particular emphasis is placed on the solitons which satisfy first-order Bogomolny equations. For these, the soliton dynamics can be investigated by finding the geodesics on the moduli space of static multi-soliton solutions. Remarkable scattering processes can be understood this way. The book starts with an introduction to classical field theory, and a survey of several mathematical techniques useful for understanding many types of topological soliton. Subsequent chapters explore key examples of solitons in one, two, three and four dimensions. The final chapter discusses the unstable sphaleron solutions which exist in several field theories. |

GIMP is a powerful, full-featured, cross-platform, and free alternative to Adobe Photoshop. Although GIMP is one of the world's most popular open source projects, with millions of users worldwide, it's notoriously difficult to use. The program lacks good documentation and many of its features remain hidden or inaccessible to casual users. The Artist's Guide to GIMP is a collection of carefully selected, practical tutorials that show the artist in all of us how to use GIMP to manipulate images and create impressive artwork for print and web use. The author focuses on the most useful features in |
