Proceedings in Nonlinear Science Centre for Nonlinear Studies, The University, Leeds LS2 9NQ, UK Series co-ordinator: Arun V. Holden Proceedings in Nonlinear Science deal with all areas of nonlinear science and its applications, and generally consist of multi-author volumes associated with select conferences and workshops within this exciting field. This series runs in parallel with the Nonlinear Science: Theories and Applications series of monographs and texts, also published by Manchester University Press. Both provide a source of up-to-date research in an immediate form. This survey addresses two crucial aspects of nonequilibrium behaviour: the interaction between chemical modes and spatial modes; and the study of transience, whether arising from fluctuations or from external disturbances. The results of a major meeting held in Brussels, Belgium, these papers deal with self-organization and nonlinear dynamics in chemistry, giving the results of recent experiments and bringing new emphasis on spatial inhomogeneities and dynamical phenomena in connection with transient behaviour and fluctuations. The principal objective of the book is to present an account of current research in this area and to stress the perspectives which it offers for future developments. P. Gray is Master of Gonville and Caius College, University of Cambridge; G. Nicolis, F. Baras, and P. Borckmans are at the Universite Libre de Bruxelles, Belgium; S. K. Scott is Lecturer in Physical Chemistry, University of Leeds.

On March 14-18, 1983 a workshop on "Chemical Instabilities: Applications in Chemistry, Engineering, Geology, and Materials Science" was held in Austin, Texas, U.S.A. It was organized jointly by the University of Texas at Austin and the Universite Libre de Bruxelles and sponsored qy NATO, NSF, the University of Texas at Austin, the International Solvay Institutes and the Ex­ xon Corporation. The present Volume includes most of the material of the in­ vited lectures delivered in the workshop as well as material from some posters, whose content was directly related to the themes of the invited lectures. In ,recent years, problems related to the stability and the nonlinear dynamics of nonequilibrium systems invaded a great num­ ber of fields ranging from abstract mathematics to biology. One of the most striking aspects of this development is that subjects reputed to be "classical" and "well-established" like chemistry, turned out to give rise to a rich variety of phenomena leading to multiple steady states and hysteresis, oscillatory behavior in time, spatial patterns, or propagating wave fronts. The primary objective of the workshop was to bring together researchers actively engaged in fields in which instabilities and nonlinear phenomena similar to those observed in chemistry are of current and primary concern : chemical engineering (especially surface catalysis), combustion (dynamics of ignition, flame sta­ bili t;y), interfaces (emulsification, dendritic growth), geology (regularly repeated patterns of mineralization 1n a variety of spabe scales), and materials science (dynamical solidification, behavior of matter under irradiation).
