The representation theory of Lie groups plays a central role in both clas sical and recent developments in many parts of mathematics and physics. In August, 1995, the Fifth Workshop on Representation Theory of Lie Groups and its Applications took place at the Universidad Nacional de Cordoba in Argentina. Organized by Joseph Wolf, Nolan Wallach, Roberto Miatello, Juan Tirao, and Jorge Vargas, the workshop offered expository courses on current research, and individual lectures on more specialized topics. The present vol ume reflects the dual character of the workshop. Many of the articles will be accessible to graduate students and others entering the field. Here is a rough outline of the mathematical content. (The editors beg the indulgence of the readers for any lapses in this preface in the high standards of historical and mathematical accuracy that were imposed on the authors of the articles. ) Connections between flag varieties and representation theory for real re ductive groups have been studied for almost fifty years, from the work of Gelfand and Naimark on principal series representations to that of Beilinson and Bernstein on localization. The article of Wolf provides a detailed introduc tion to the analytic side of these developments. He describes the construction of standard tempered representations in terms of square-integrable partially harmonic forms (on certain real group orbits on a flag variety), and outlines the ingredients in the Plancherel formula. Finally, he describes recent work on the complex geometry of real group orbits on partial flag varieties."

Subjectivity, the speaker's expression of self in discourse, is a relatively under-researched area in the field of applied linguistics: this book examines the role of subjectivity in the context of second language use. Drawing on insights from discourse analysis and pragmatics, it describes how a group of students studying French at degree level at the University of Cambridge, England, convey expressions of subjectivity in personal narratives and argumentative language. In this book, the author begins by introducing the reader to key areas in the study of discourse. Using a methodology that has much in common with descriptive linguistics, he provides a wide-ranging account of how forms in language are used to convey the expression of subjectivity. His particular concern is to examine how these markers of subjectivity are used differently by native and non-native speakers of French. The discussion is carefully supplemented throughout with a variety of exemplification and discourse types, including personal narratives in French and English and transcripts of video-taped interactions in role-plays. In the course of his analysis, the author questions long-held assumptions about the way French is taught in secondary schools and in higher education institutions. The range of issues discussed, as well as the variety of examples used, will make this a valuable book not only for students of applied linguistics but also for any reader wishing to gain a deeper understanding of how the expression of subjectivity can contribute to the learning of a second language.
