ISAAC has organized these biannual meetings since 1997; previous Congresses were held in Newark, DE, USA (1997) and Fukuoka, Japan (1999). The Congress Proceedings have been published in a special series since 1998 by Kluwer Academic Publishers. These meetings attempt to provide an appropriate forum for both "pure and applied" mathematicians, stressing their common grounds in broad areas of analysis. The complete Congress details can be found on the web at http://www.math.udel.edu/isaac (click on "Third International ISAAC Congress'2001"). Further ISAAC information can be found at http://www.math.fu-berlin.de/rd/ag/isaac We are organizing a number of special sessions centered around DIRECT and INVERSE WAVE PROPAGATION and SCATTERING, and would like to invite you to speak in one of these sessions. Please reply, either way, by January 15, 2001 by e-mail to . If you intend to participate, please forward your complete postal mailing address, e-mail address, telephone and fax numbers, and a tentative talk title with your e-mail reply.

Strongin Nizhni Novgorod State University, Russia Yaroslav D. Sergeyev Institute of Systems Analysis and Information Technology of the CNR, c/o University of Calabria, Italy and Nizhni Novgorod State University, Russia NONCONVEX OPTIMIZATION AND ITS APPLICATIONS Volume 45 This book presents a new approach to global non-convex constrained optimization. Problem dimensionality is reduced via space-filling curves. To economize the search, constraint is accounted separately (penalties are not employed). The multicriteria case is also considered. All techniques are generalized for (non-redundant) execution on multiprocessor systems. Audience: Researchers and students working in optimization, applied mathematics, and computer science.

More than six years after the publication of the last special issue, it is time to take stock of recent and current interactions between Linear Algebra and Systems Theory. The cross fertilization between these two fields has been very fruitful in the past. While linear algebraic methods have been instrumental for much of the development of linear systems theory, many system theoretic concepts and constructions are now part of the body of linear algebra. Today systems theory is a place where methods from many different parts of mathematics are combined. As a result linear systems theory has become a rich source of linear algebraic problems. More recently, new paradigms, new problems and areas of application have appeared on the scene: the behavioural approach, coding theory, distance problems and parameter uncertainty, the dynamic systems approach to algorithms, computational complexity issues in systems theory and discrete event systems. These important subject areas have enriched linear systems theory and will influence the future development of linear algebra, too. We hope that the upcoming issue will further this process and we encourage all authors working in these areas to submit their contributions. As in previous issues, this one will be open for all papers with significant new results in Systems and Control Theory where either linear algebraic methods play an important role or new tools and problems of linear algebraic nature are presented. Also survey papers are very welcome which illustrate specific areas where the interaction of Systems Theory and Linear Algebra has been particularly successful. Papers must meet the publication standards of Linear Algebra and Its Applications and will be refereed in the usual way. Areas and topics of interest for this special issue include: - Structure theory of linear systems and system families - Stability theory - Distance problems and analysis of uncertain systems - Methods of robust control - Approximation and interpolation problems arising in systems theory - Geometric control theory and geometry of linear systems - Linear behaviors - Multidimensional systems and systems over rings - Module theoretic techniques in system theory - Coding theory with connections to systems theory - Algorithms for linear systems - Numerical issues in linear systems theory - Computational complexity in linear algebra and systems theory - Discrete event systems The deadline for submission of papers is 15 February 2001, and the special issue is expected to be published in 2002.
