Since the appearance of computers, numerical methods for discontinuous solutions of quasi-linear hyperbolic systems of partial differential equations have been among the most important research subjects in numerical analysis. The authors have developed a new difference method (named the singularity-separating method) for quasi-linear hyperbolic systems of partial differential equations. Its most important feature is that it possesses a high accuracy even for problems with singularities such as schocks, contact discontinuities, rarefaction waves and detonations. Besides the thorough description of the method itself, its mathematical foundation (stability-convergence theory of difference schemes for initial-boundary-value hyperbolic problems) and its application to supersonic flow around bodies are discussed. Further, the method of lines and its application to blunt body problems and conical flow problems are described in detail. This book should soon be an important working basis for both graduate students and researchers in the field of partial differential equations as well as in mathematical physics.

In the early part of the twentieth century, Buenos Aires erupted from its colonial past as a city in its own right, expressing a unique and vibrant cultural identity.Intersecting Tango engages the city at this key moment, exploring the sweeping changes of 1900-1930 to capture this culture in motion through which Buenos Aires transformed itself into a modern, cosmopolitan city. Taking the reader through a dazzling array of sites, sources, and events, Bergero conveys the city in all its complexity. Drawing on architecture and gendered spaces, photography, newspaper columns, schoolbooks, "high" and "low" literature, private letters, advertising, fashion, and popular music, she illuminates a range of urban social geographies inhabited by the city's defining classes and groups. In mining this vast material, Bergero traces the profound change in social fabric by which these diverse identities evolved, through the processes of modernization and its many dislocations, into a new national identity capable of embodying modernity. In her interdisciplinary study of urban development and cultural encounters with modernity, Bergero leads the reader through the city's emergence, collecting her investigations around the many economic, social, and gender issues remarkably conveyed by the tango, the defining icon of Buenos Aires. Multifaceted and original, Intersecting Tango is as rich and captivating as the dance itself.

Marc A. Krell analyzes the theologies of four twentieth-century Jewish thinkers - Hans Joachim Schoeps, Franz Rosenzweig, Richard Rubenstein, and Irving Greenberg - who have constructed theologies based on their interaction with Christian thought and culture. Their work reflects a common attempt to understand the impact of Christian culture on the historical events prior to and following the Holocaust, and to reevaluate the relationship between the two religions in light of a history of theological anti-Judaism and modern, racial antisemitism.

Adrienne Kennedy's plays have been highly regarded in the world of American theater for many years. Intersecting Boundaries, a collage of fascinating essays and interviews that represents the first major critical study of her work, explores the complexity and richness of Kennedy's innovative dramas.
