The 1996 NATO Advanced Study Institute (ASI) followed the international tradi­ tion of the schools held in Cargese in 1976, 1979, 1983, 1987 and 1991. Impressive progress in quantum field theory had been made since the last school in 1991. Much of it is connected with the interplay of quantum theory and the structure of space time, including canonical gravity, black holes, string theory, application of noncommutative differential geometry, and quantum symmetries. In addition there had recently been important advances in quantum field theory which exploited the electromagnetic duality in certain supersymmetric gauge theories. The school reviewed these developments. Lectures were included to explain how the "monopole equations" of Seiberg and Witten can be exploited. They were presented by E. Rabinovici, and supplemented by an extra 2 hours of lectures by A. Bilal. Both the N = 1 and N = 2 supersymmetric Yang Mills theory and resulting equivalences between field theories with different gauge group were discussed in detail. There are several roads to quantum space time and a unification of quantum theory and gravity. There is increasing evidence that canonical gravity might be a consistent theory after all when treated in. a nonperturbative fashion. H. Nicolai presented a series of introductory lectures. He dealt in detail with an integrable model which is obtained by dimensional reduction in the presence of a symmetry.

Soon after the discovery of quantum mechanics, group theoretical methods were used extensively in order to exploit rotational symmetry and classify atomic spectra. And until recently it was thought that symmetries in quantum mechanics should be groups. But it is not so. There are more general algebras, equipped with suitable structure, which admit a perfectly conventional interpretation as a symmetry of a quantum mechanical system. In any case, a "trivial representation" of the algebra is defined, and a tensor product of representations. But in contrast with groups, this tensor product needs to be neither commutative nor associative. Quantum groups are special cases, in which associativity is preserved. The exploitation of such "Quantum Symmetries" was a central theme at the Ad­ vanced Study Institute. Introductory lectures were presented to familiarize the participants with the al­ gebras which can appear as symmetries and with their properties. Some models of local field theories were discussed in detail which have some such symmetries, in par­ ticular conformal field theories and their perturbations. Lattice models provide many examples of quantum theories with quantum symmetries. They were also covered at the school. Finally, the symmetries which are the cause of the solubility of inte­ grable models are also quantum symmetries of this kind. Some such models and their nonlocal conserved currents were discussed.

Nach gut acht Jahren erscheint der lange erwartete sechste Band des Gesamtwerks von Herzog amp de Meuron zu den Jahren 2 5 bis 2 7. Die rund Projekte zeigen die Schweizer Architekten auf der Höhe ihres Könnens. Darunter finden sich so ikonische Bauten wie Das Perez Art Museum in Miami und das VitraHaus in Weil am Rhein. Die Entwürfe dieses Bandes breiten das ganze Vokabular architektonischer Mittel aus und reagieren äusserst vielfältig auf aktuelle Entwicklungen der Epoche. Vom kleinen Umbauprojekt eines Privathauses über ein Atelier-Ensemble bis zu Wohntürmen und städtebaulichen Projekten im grossen Massstab wird die Auseinandersetzung mit dem Ort verfeinert. Dabei entwickeln Herzog amp de Meuron immer wieder neue Verfahren und schlagen Bezüge zum Vokabular der klassischen Moderne und zur eigenen Werkgeschichte. Architektur wird zum Mittel, einer zunehmend virtuell geprägten Welt Körperhaftigkeit und Halt zu geben.

After eight years, the new volume on the complete works of Herzog & de Meuron is published covering the years 2005 to 2007. The book presents 60 projects, which show the architects at the height of their powers. Their designs encompass the full range of architectural devices and respond to contemporary developments with a wide range of solutions – the designs refine the interaction with the respective site, with projects ranging from a small private conversion project to a studio ensemble, through to residential towers and urban design projects. For their designs, Herzog & de Meuron again develop new processes and create references to classic modernism just as to their own oeuvre. Architecture becomes a means of providing physical presence and stability in an increasingly virtual world.

The long-awaited fifth volume on The Complete Works of Herzog amp de Meuron presents the sixty projects completed between 2 2 and 2 4 with characteristic attention to detail. These include buildings that have already become contemporary architectural icons, such as the National Stadium in Beijing and the Elbphilharmonie in Hamburg, but also projects which, though never realized, have influenced the architectural discourse. These include the residential tower for the Schatzalp Hotel, which overlooks Davos and inspired a new generation of Alpine architecture. In the period covered by this volume, urban planing was a major focus of Herzog amp de Meuron's work. International acclaim fueled by booming construction led to numerous commissions in China (the Jindong New Development Area), and in Europe: master plans for Jerez de la Frontera and the Olympic Games in London opened up entire urban regions to future development.

Der lang erwartete fünfte Band des Gesamtwerks von Herzog amp de Meuron stellt die sechzig Projekte der Jahre 2 2 bis 2 4 mit der charakteristischen Sorgfalt vor. Dazu zählen Bauten, die bereits zu den Architekturikonen der Gegenwart avancierten, wie das Olympiastadion in Peking und die Elbphilharmonie in Hamburg aber auch Projekte, die, obwohl sie unrealisiert blieben, den architektonischen Diskurs geprägt haben, wie der Wohnturm für das Hotel Schatzalp oberhalb von Davos, der dem Bauen in den Alpen neue Impulse gab. Im vorliegenden Zeitraum erfährt der Städtebau eine besondere Aufmerksamkeit des Architekturbüros. Der Architekturboom im China jener Jahre hat Planungen für ganze Quartiere hervorgebracht. Davon zeugen die Masterpläne für Jindong New Development Area in China, für Jerez de la Frontera in Spanien oder für die Olympischen Spiele in London, die ganze Stadtregionen für die Zukunft öffneten.

The Elbphilharmonie is Hamburg’s new landmark and is already an icon of contemporary architecture. In this book, Herzog & de Meuron document their project: extensive archive material, plans, and photographs are used to illustrate the process of the creation of this once-in-a-hundred-years building from the first sketch and the various design stages with their many challenges, through to completion of the finished building. The dialog between historical brick plinth and contemporary glass crystal, the combination of different functions, the development of the spectacular large concert hall, the design of a public plaza for the population are just some of the many aspects that contribute to the attractiveness of the building.

On the occasion of the 40th anniversary of the worldwide leading architectural practice Herzog & de Meuron, we are publishing the second volume of the Complete Works as an accessible paperback edition. The reprint, in original format, comprehensively present all buildings and designs from 1989 up to the year 1991. The development of the practice over the first years can be tracked in fascinating documents of the time.

The monograph provides a sharply focused insight into how Annette Gigon and Mike Guyer understand architecture. The various concepts as well as the different constructions, materials, forms and colors that they employ in their projects are presented in an exhaustive documentation of their work that uses numerous photographs, plans and short texts. The three essays as well as a discussion between Patrick Gmur, Martin Steinmann and the architects offer in-depth reflection and contextualization.

How to deal with historic buildings has long been a core issue of the international architectural discourse. Herzog & de Meuron began addressing the potential of existing structures very early on: the maintenance and alteration of buildings are among the key strategies of the architects. For the Park Avenue Armory in New York, Herzog & de Meuron have designed a new model for dealing with monuments. The historical building was opened in 1881 on the Upper East Side of Manhattan as a meeting place and training ground for the National Guard, and boasts a rich mixture of different styles. Herzog & de Meuron developed a multifaceted strategy for the transformation of the building, now used as a cultural center, that allows for a combination of restoration, transformation, and innovation. From the exposing of historic structures to the addition of new elements, the architecture gained new vibrancy from the considered entanglement of different aspects. In the current debate, this departure from the practice of historic preservation in the United States is, beyond its value as an actual example, a unique contribution that unfolds in close reference to material. It is exemplary and groundbreaking.

Kurt Symanzik was certainly one of the most outstanding theoretical physicists of our time. For thirty years, until his untimely death in 1983, he helped to shape the present form of quantum field theory and its application to elementary particle physics. In memoriam of Kurt" Symanzik leading scientists present their most recent results, giving, at the same time, an overview of the state of the art. This collection was originally published in Vol. 97, 1/2 (1985) of Communications in Mathematical Physics. They range over various inter­ related topics of interest to Kurt Symanzik. We hope that making this collection available in an accessible and inexpensive way will benefit the physics community. The Publisher Contents To the Memory of Kurt Symanzik 1 By A. Jaffe, H.

The second volume of the complete works of Herzog & de Meuron covers the years 1989-1991 and 32 project-designs. It includes well-known buildings such as the copper-clad signal box and the locomotive depot in Basel, the museum for the Goetz art collection in Munich, the student residences on the university campus in Dijon and the Pfaffenholz sports complex in St. Louis. The large-scale study Basel, A City in the Making, but also the master plans for the university campus in Dijon and the new district of Sils Cuncas in the Upper Engadine are among the urban planning analyses that constitute the main focus of the volume.

The Tate Modern in London made Herzog & de Meuron famous all over the world. The projects and structures they have built since then are distinguished by the sensitive treatment of materials for which the architects are renowned. In addition, these Pritzker Prize–winning architects have developed a topographical conception of architecture that not only locates their designs in a larger context but also frequently structures them as landscapes. In order to represent them, the layout of volume 4 of the complete works has been completely redesigned. The publication contains essays by the architects themselves in which they situate their projects. The structures presented include such icons of contemporary architecture as the Prada store in Tokyo Aoyama and the Allianz Arena in Munich, where the opening game of the 2006 Soccer World Cup was played. Pathbreaking museum structures such as the Schaulager near Basel, the Walker Art Center in Minneapolis, and the De Young Museum in San Francisco continue the conversation surrounding what constitutes a truly contemporary presentation of modern art. Covers all designs and structures on which planning began between 1997 and 2001 With roughly 2.000 color and black-and-white illustrations, plans, and sketches The indispensable reference work for everyone interested in Herzog & de Meuron

On the occasion of the 40th anniversary of the worldwide leading architectural practice Herzog & de Meuron, we are publishing the first three volumes of the Complete Works as an accessible paperback edition. The reprints, in original format, comprehensively present all buildings and designs from its beginnings in 1978 up to the year 1996. The development of the practice over the first two decades can be tracked in fascinating documents of the time: from the completion of local projects like the Blue House and Ricola Storage Building to world-famous icons such as the Tate Modern and the Dominus Winery.

This volume traces the development of the work of the Basle architects Herzog and de Meuron in the first 11 years. Much emphasis is placed on the initial design processes, made tangible through plans and sketches. Finished buildings are presented in great detail.
