My new numbers are as follows: Max Gunzburger 515-294-1752 Department of Mathematics 515-294-5454 (fax) Ames IA 50011-2064 gunzburg@iastate.edu Thanks Max ------------------------------ From: Bengt Fornberg Date: Sat, 20 Jan 1996 10:29:12 -0700 (MST) Subject: New Book on Pseudospectral Methods Bengt Fornberg: "A Practical Guide to Pseudospectral Methods", Volume 1 in "Cambridge Monographs on Applied and Computational Mathematics", Cambridge University Press 1996, 231 pages, ISBN 0-521-49582-2. This book explains how, when, and why pseudospectral methods work, focusing more on illustrations and heuristic explanations than on rigorous (functional-theoretical) arguments. A key theme is to explore - and exploit - the close connection that exists between pseudospectral- and finite difference methods. ------------------------------ From: Alan Harvey Date: Fri, 19 Jan 1996 10:02:43 -0800 (PST) Subject: New Book on Numerical Analysis of Differential Equations I'm pleased to announce the publication of a new book of interest to NA-net: A First Course in the Numerical Analysis of Differential Equations Arieh Iserles University of Cambridge Numerical analysis presents different faces to the world. For mathematicians it is a bona fide mathematical theory with an applicable flavour. For scientists and engineers it is a practical, applied subject, part of the standard repertoire of modelling techniques. For computer scientists it is a theory on the interplay of computer architecture and algorithms for real-number calculations. It is the tension between these standpoints that is the driving force of this book, which presents a rigorous account of the fundamentals of numerical analysis of both ordinary and partial differential equations. The point of departure is mathematical but the exposition strives to maintain a balance between theoretical, algorithmic and applied aspects of the subject. In detail, topics covered include numerical solution of ordinary differential equations by multistep and Runge--Kutta methods; finite difference and finite elements techniques for the Poisson equation; a variety of algorithms to solve large, sparse algebraic systems; methods for parabolic and hyperbolic differential equations and techniques of their analysis. The book is accompanied by an appendix that presents brief back-up in a number of mathematical topics. Dr Iserles concentrates on fundamentals: deriving methods from first principles, analysing them with a variety of mathematical techniques and occasionally discussing questions of implementation and applications. By doing so, he is able to lead the reader to theoretical understanding of the subject without neglecting its practical aspects. The outcome is a textbook that is mathematically honest and rigorous and provides its target audience with a wide range of skills in both ordinary and partial differential equations. PART I.

Engl Date: Mon, 15 Jan 1996 10:29:43 EST Subject: Inverse Problems in Wave Propagation Conference on Inverse Problems in Wave Propagation and Diffraction Aix les Bains (France) September 23-27, 1996 SIAM and GAMM have been conducting a conference series on various application fields of inverse problems; the committee for this series is chaired by H.W.Engl (Linz) and W.Rundell (College Station, USA) and includes also A.Louis (Saarbr|cken) and D.Colton (Delaware). The first conferences were on Inverse Problems in Diffusion Processes (St.Wolfgang, June 1994) and on Inverse Problems in Geophysics (California, December 1995). Proceedings have been published (and will be published, respectively) by SIAM. After a conference on Inverse Problems in Medical Imaging and Nondestructive Testing in Oberwolfach (February 1996; not formally part of this series, but chaired by H.W.Engl, A.Louis, and W.Rundell, hence coordinated with the series), the next conference will be coorganized with INRIA and chaired by G. Chavent and P.C.Sabatier. According to their call for papers, it will focus on modeling, mathematical analysis, and the numerical solution of inverse problems in wave propagation and diffraction. The targeted audience is multidisciplinary. The organizers hope to incite successful exchanges between the specialists in applied fields and those whose academic background and interest are more centered on mathematics. The conference takes place in Aix les Bains in the French Alps between September 23 and 27, 1996. Abstracts should be submitted by March 1 to INRIA Rocquencourt M.-C.Sance Relations exterieurs Bureau des cours et colloques B.P. 105 F-78153 Le Chesnay Cedex France.

Numerous advances have been reported in these conferences since they started in 1978. The continuous success of applying BEM to difficult engineering and scientific problems has resulted in it continuing to be an area of very active research. Much of the new analytical research has contributed in developing better tools for the solution of non-linear and time-dependent problems. Practising engineers, on the other hand, envisage the implementation of the technique as an analysis and design tool. Considerable advances have also been made in the solution of complex fluid dynamics problems and the use of high performance computing. BEM can now solve complex engineering problems and has been accepted as an alternative to other analysis techniques. The conference will deal with the topics listed over the page as well as papers of a more theoretical character, state of the art reviews and advance mathematical and computational aspects. This conference is internationally recognised as the forum for boundary element research and continues to attract a large number of well established practitioners. The conference has held a special appeal to young researchers who are actively involved in advances of Boundary Elements. The meeting is a unique forum in which they can present and discuss their ideas with their colleagues. The meeting has always been characterized by its friendly atmosphere, collaboration and mutual respect which are trademarks of authentic researchers.

The position is open in the framework of the ESPRIT contract PINEAPL in connection with European research centres and industrial partners. The leader of the project is NAG. For this project we want someone with experience both in numerical software techniques and parallel computing. The work can commence immediately. Normally the position is for one year with possible extensions to a second year. The heart of the activity concerns the numerical reliability of software. There exist methods for analysing models and algorithms that give an indication of the confidence to be placed in the accuracy of simulation results. The task to be completed at CERFACS consists mainly in developing a tool which employs these methods, called PRECISE, that will be used in the project for confidence testing of algorithms and applications. A prototype tool already exists so the consortium can begin testing internally early in the project. The prototype version is written for Matlab and one of the aims of the task is to improve its capabilities. Some of the work will be in translating PRECISE to Fortran to allow larger (and more realistic) problems to be handled and in the production of commercial quality documentation for the tool. This position is in the framework of the Parallel Algorithms Project and within the Qualitative Computing Group.
