Fruit d’un travail en partenariat, cet atlas offre une lecture de l’agglomération de La Paz, composée de la municipalité éponyme et de celle d’El Alto. Le déchiffrage qu’il propose se veut résolument novateur dans la mesure où les deux villes sont habituellement montrées séparément, sans jamais prendre en compte l’évidence de leur interdépendance. Si l’histoire de la construction de ces deux municipalités explique pourquoi elles s’ignorent sur le plan institutionnel, l’analyse de différentes cartes indique au contraire que ces deux municipalités ne forment qu’une seule et même agglomération. El Alto et La Paz, l’en haut et l’en bas, constituent un tout : elles sont à la fois dissociées et indissociables fonctionnellement et morphologiquement. L’atlas fait donc ressortir quelques-uns des problèmes que pose le couple La Paz-El Alto. Ces problèmes alimentent la vulnérabilité de l’agglomération. Mais les cartes de cet atlas démontrent aussi que la gestion des risques, notamment des situations d’urgence et de crise, constitue un substrat concret de collaboration et de rapprochement des deux villes.

Electronic structure problems are studied in condensed matter physics and theoretical chemistry to provide important insights into the properties of matter. This 2006 graduate textbook describes the main theoretical approaches and computational techniques, from the simplest approximations to the most sophisticated methods. It starts with a detailed description of the various theoretical approaches to calculating the electronic structure of solids and molecules, including density-functional theory and chemical methods based on Hartree-Fock theory. The basic approximations are thoroughly discussed, and an in-depth overview of recent advances and alternative approaches in DFT is given. The second part discusses the different practical methods used to solve the electronic structure problem computationally, for both DFT and Hartree-Fock approaches. Adopting a unique and open approach, this textbook is aimed at graduate students in physics and chemistry, and is intended to improve communication between these communities. It also serves as a reference for researchers entering the field.

Density Functional Theory (DFT) has firmly established itself as the workhorse for the atomic-level simulation of condensed matter phases, pure or composite materials and quantum chemical systems. The present book is a rigorous and detailed introduction to the foundations up to and including such advanced topics as orbital-dependent functionals and both time-dependent and relativistic DFT. Given the many ramifications of contemporary DFT, this text concentrates on the self-contained presentation of the basics of the most widely used DFT variants. This implies a thorough discussion of the corresponding existence theorems and effective single particle equations, as well as of key approximations utilized in implementations. The formal results are complemented by selected quantitative results, which primarily aim at illustrating strengths and weaknesses of a particular approach or functional. DFT for superconducting or nuclear and hadronic systems are not addressed in this work. The structure and material contained in this book allow for a tutorial and modular self-study approach: the reader will find that all concepts of many-body theory which are indispensable for the discussion of DFT - such as the single-particle Green’s function or response functions - are introduced step by step, rather than just used. The same applies to some basic notions of solid state theory, as, for instance, the Fermi surface. Also, the language of second quantization is introduced systematically in an Appendix for readers without a formal theoretical physics background.

Dans les pays du Sud, l’urbanisation rapide induit des changements majeurs environnementaux, démographiques, sociaux, culturels et sanitaires. Les taux de croissance des villes africaines restent très importants, de l’ordre de 4 à 5 % l’an : la moitié de la population ouest-africaine pourrait vivre en milieu urbain d’ici 2020. Ouagadougou, capitale administrative du Burkina Faso, connaît un processus d’urbanisation exemplaire parmi les pays africains sahéliens pauvres et traditionnellement ruraux. Elle compte un peu plus d’un million d’habitants en 2006, soit environ 45 % de la population citadine du pays. Sa croissance a été importante et mal contrôlée par les autorités jusqu’à la Révolution de 1983. Bien qu’un gros effort ait été fait depuis cette date, l’ensemble urbain reste encore hétérogène, associant un centre-ville moderne, des zones d’habitat dense, parfois insalubres et des fronts d’urbanisation irrégulière. Les quartiers sont différenciés tant par leur structure démographique que par leur accès aux services : approvisionnement en eau, assainissement, offre de soins, écoles et marchés. Cet atlas présente l’évolution de la ville depuis la période coloniale jusqu’à aujourd’hui, selon trois thématiques : l’évolution spatiale de la ville ; les différenciations de l’espace en fonction de la population et de l’habitat ; la structuration de l’espace par rapport aux équipements collectifs. Dans cet ouvrage, une attention particulière a été portée à la compilation de données anciennes et récentes. Ces données montrent comment, en fonction d’éléments géographiques objectifs liés aux habitants et à leurs conditions de vie, se distinguent des villes dans la ville.
