Parametrized Measures and Variational Principles

By: Pablo Pedregal

Weak convergence is a basic tool of modern nonlinear analysis because it enjoys the same compactness properties that finite dimensional spaces do: basically, bounded sequences are weak relatively compact sets. Nonetheless, weak conver gence does not behave as one would desire with respect to nonlinear functionals and operations. This difficulty is what makes nonlinear analysis much harder than would normally be expected. Parametrized measures is a device to under stand weak convergence and its behavior with respect to nonlinear functionals. Under suitable hypotheses, it yields a way of representing through integrals weak limits of compositions with nonlinear functions. It is particularly helpful in comprehending oscillatory phenomena and in keeping track of how oscilla tions change when a nonlinear functional is applied. Weak convergence also plays a fundamental role in the modern treatment of the calculus of variations, again because uniform bounds in norm for se quences allow to have weak convergent subsequences. In order to achieve the existence of minimizers for a particular functional, the property of weak lower semicontinuity should be established first. This is the crucial and most delicate step in the so-called direct method of the calculus of variations. A fairly large amount of work has been devoted to determine under what assumptions we can have this lower semicontinuity with respect to weak topologies for nonlin ear functionals in the form of integrals. The conclusion of all this work is that some type of convexity, understood in a broader sense, is usually involved.

A Variational Approach to Optimal Control of ODEs

By: Pablo Pedregal

This self-contained book presents in a unified, systematic way the basic principles of optimal control governed by ODEs. Using a variational perspective, the author incorporates important restrictions like constraints for control and state, as well as the state system itself, into the equivalent variational reformulation of the problem. The fundamental issues of existence of optimal solutions, optimality conditions, and numerical approximation are then examined from this variational viewpoint. Inside, readers will find a unified approach to all the basic issues of optimal control, academic and real-world examples testing the book’s variational approach, and a rigorous treatment stressing ideas and arguments rather than the underlying mathematical formalism. A Variational Approach to Optimal Control of ODEs is mainly for applied analysts, applied mathematicians, and control engineers, but will also be helpful to other scientists and engineers who want to understand the basic principles of optimal control governed by ODEs. It requires no prerequisites in variational problems or expertise in numerical approximation. It can be used for a first course in optimal control.

Optimal Design through the Sub-Relaxation Method

Understanding the Basic Principles

By: Pablo Pedregal

This book provides a comprehensive guide to analyzing and solving optimal design problems in continuous media by means of the so-called sub-relaxation method. Though the underlying ideas are borrowed from other, more classical approaches, here they are used and organized in a novel way, yielding a distinct perspective on how to approach this kind of optimization problems. Starting with a discussion of the background motivation, the book broadly explains the sub-relaxation method in general terms, helping readers to grasp, from the very beginning, the driving idea and where the text is heading. In addition to the analytical content of the method, it examines practical issues like optimality and numerical approximation. Though the primary focus is on the development of the method for the conductivity context, the book’s final two chapters explore several extensions of the method to other problems, as well as formal proofs. The text can be used for a graduate course in optimal design, even if the method would require some familiarity with the main analytical issues associated with this type of problems. This can be addressed with the help of the provided bibliography.

A History of Infamy

Crime, Truth, and Justice in Mexico

By: Pablo Piccato

A History of Infamy explores the broken nexus between crime, justice, and truth in mid-twentieth-century Mexico. Faced with the violence and impunity that defined politics, policing, and the judicial system in post-revolutionary times, Mexicans sought truth and justice outside state institutions. During this period, criminal news and crime fiction flourished. Civil society’s search for truth and justice led, paradoxically, to the normalization of extrajudicial violence and neglect of the rights of victims. As Pablo Piccato demonstrates, ordinary people in Mexico have made crime and punishment central concerns of the public sphere during the last century, and in doing so have shaped crime and violence in our times.

SACA

By: Gonzalo de Pablo

En principio la narrativa se produce con la sencillez del cotidiano vivir. Sin asperezas, lisa y llanamente, como el ro de mansas aguas que se preparan para cambiar el curso, convirtiendo el suave deslizar en violenta torrentera. Los pueblos de Espaa, desquiciados se lanzan y envuelven en una guerra fratricida, las ciudades, campos y aldeas se desbordan, la sangre salpica las familias sin distincin de bando o creencia. Como hongos brotan los CAMPOS DE CONCENTRACIN, LOS BATALLONES DE TRABAJO FORZADO, el peregrinar por las CRCELES de reclusos para finalmente, llegar al pi del PAREDN, calificado con la expresiva palabra ?SACA?. Este es el contenido de gran parte del libro que te dispones a leer. Es el relato verdico del protagonista principal de la obra, con el deseo, amigo lector, de que evites la repeticin del drama, que arras nuestra Patria.

A new Compact History of Mexico.

By: Pablo Escalante Gonzalbo,Bernardo García Martínez,Luis Jáuregui,Josefina Zoraida Vázquez,Elisa Speckman Guerra,Javier Garciadiego,Luis Aboites Aguilar

In 1973, El Colegio de México published the first version of Historia mínima de México (followed in 1974 by the English translation A Compact History of Mexico) for the purpose of providing Mexicans living at that time with basic historical knowledge of their country. While preserving the aim of synthesis and simplicity that served as a basic guideline for the earlier Historia mínima de México, this new work constitutes a completely novel and original manuscript. Thus, A New Compact History of México is not only a “new history,” but also an innovative one. In its pages, readers will find accounts and perspectives enabling them to gain a fundamental understanding of Mexican history in an enjoyable way.

From The Finca To The Maquila

Labor And Capitalist Development In Central America

By: Juan Pablo Perez Sainz

This book presents an analysis of contemporary Central American from a social perspective and, more specifically, from that of one of its main components: the world of labor. Despite undeniable changes, this world is still made up of three basic logics. Labor markets reflect an inability to generate sufficient employment. Labor relations remain precarious. And labor subjects and actors solid enough for their voice to be heard have not managed to establish themselves. The result is that the world of labor in Central America is still marked by vulnerability. }The oligarchic crises in Central America has provoked a variety of responses at different levels during the last decades. The development of new agroexports in the 1950s, the import substitution industrialization of the 1960s, and the current opening up of trade along with the development of new tradables sectors under the influence of globalization, represent attempts to modernize the regions economies. The same has occurred at the political level with the current democratization processes that have meant competitive elections taking place in all the countries. It is at the social level that responses have been most weak and levels of poverty remain extremely high. This book presents an analysis of contemporary Central American history from a social perspective and, more specifically, from that of one of its main components: the world of labor.

Bionomics and Identification of the Genus Rotylenchus (Nematoda: Hoplolaimidae)

By: Pablo Castillo,Nicola Vovlas

The spiral plant-parasitic nematode genus Rotylenchus contains a cosmopolitan group of nematodes that is predominantly found in temperate regions of the world. In this genus are included a number of species of significant economic importance in agriculture. They parasitize a wide-range of hosts, including vegetables, ornamentals, and fruit and forest trees. The book comprises seven sections and presents summarised and specialised information on various aspects of the spiral nematodes belonging to the genus Rotylenchus. Sections 1 and 2 describe the importance of Rotylenchus species in agricultural crops, their distribution and numerous aspects of their biology, feeding habits, pathogenicity to vegetables, fruit and forest trees, and ecology. Section 3 presents different management strategies for the most important and pathogenic species of Rotylenchus, including chemical control, crop rotation, and biological control by means of nematophagous fungi, entomopathogenic nematodes, the hyperparasitic bacteria Pasteuria penetrans, and nematicidal plants. Sections 4 and 5 describes the most important morphological characters used in characterising and diagnosing species, as well as a broad discussion on the taxonomy and systematics in Rotylenchus and related genera, including a list of nominal species. These sections also include morphometric and cluster analyses in order to separate groups of species in order to facilitate identification. Section 6 provides a complete description and measurements of all populations characterised for each species, as well as their world distribution. Finally, Section 7 includes comprehensive tabular and dichotomous keys for species identification.
