Traditionally, Lorentzian geometry has been used as a necessary tool to understand general relativity, as well as to explore new genuine geometric behaviors, far from classical Riemannian techniques.Recent progress has attracted a renewed interest in this theoryfor many researchers: long-standing global open problems have been solved, outstanding Lorentzian spaces and groups have been classified, new applications to mathematical relativity and high energy physics have been found, and further connections with other geometries have been developed.

Samplesof these fresh trends are presented in this volume, based on contributions from the VI International Meeting on Lorentzian Geometry, held at the University of Granada, Spain, in September, 2011. Topics such as geodesics, maximal, trapped and constant mean curvature submanifolds, classifications of manifolds with relevant symmetries, relations between Lorentzian and Finslerian geometries, and applications to mathematical physics are included.

This book will be suitable for a broad audience of differential geometers, mathematical physicists and relativists, and researchers in the field."

This beginner's guide is packed with information, tips, and tricks, based on the author's extensive experience with Apache Roller. In next to no time, you will be able to build and deploy your own blog. The clear and concise hands-on exercises will teach you everything you need to know to install, configure, and use Apache Roller, along with the open source software required to run it. The book includes plenty of illustrations to guide you through all the detailed exercises and tutorials, so you can get the most out of every chapter. If you are interested in establishing a blog, using Apache Roller and popular web applications to write attractive posts and promote your blog on all the major social bookmarking services, this book is for you. No previous experience on Tomcat, MySQL, the Apache Web Server, or Linux is required.

El Peru, al igual que otros paises de America Latina, no debe imitar el modelo energetico de paises industrializados, debido a la acelerada produccion de gases de efecto invernadero (GEI). Es por ello, que la matriz energetica del pais debe orientarse al uso de fuente de energia renovable, lo cual constituiria una politica energetica que involucre el empleo de tecnologias y procesos de mayor eficiencia y ahorro energetico, cuya problematica y alternativa de uso de energia se tratan en este libro.
