While the presentation and publication of papers at the Seminars are encouraged, the primary aim is to stimulate discussion and liaison between specialist groups. The President of EUROTHERM in 1996 - 2000 is Dr Gian Piero Celata, ENEA, Rome / Italy (Fax: +390630483026; E-mail : celata@casaccia. enea.it). The Secretary is Professor Paolo Tartarini, University of Modena/Italy (Fax: +39 059 376 799; E-mail : tartarini@unimo.it). Information on the EUROTHERM Committee and its activities is available on the Internet at: http://termserv.casaccia.enea.it/eurotherm/ Background: Inverse problems are related to the determination of unknown causes from known consequences (the measurements). Aspects relative to the function estimation or the parameter identification can then be considered. This seminar is the first one on Inverse Problems in the framework of the Eurotherm seminars but is linked to other conferences on Inverse Problems that have been held throughout the world, for example the three ICIPE* conferences: Port Ludow (1999), Le Croisic (1996) and Palm Coast (1994). *International Conference on Inverse Problem in Engineering Scope of the seminar: In the framework of this congress, the recent developments in the resolution of inverse problems, the most recent applications and the links between modelling and experimentation will be presented. It will assist with the dissemination throughout the research and industrial worlds. The new ideas between the methods and their use with experimental data will be emphasised. The following topics will be included but papers on related topics are also encouraged: Mathematical aspects, optimisation and methodology in inverse problems. Inverse problems in heat and mass transfer, mechanics, acoustic, etc. Metrology, experimental methods, non intrusive measurements and optimum design problems. Data acquisitions, signal treatment, image processing, tomography, etc. Active transfer control. To illustrate the benefits of improved methods, most of the papers should contain heat and mass transfer applications. Original developments relating to diffusive transport, are welcome and a specific effort will be made to include papers concerning inverse problems in convection and radiation. All the couplings between thermal and mechanical systems are particularly welcome as well as contributions in porous media. Instructions for authors and deadlines: All papers must be written in English. All the communications will be presented orally. Abstracts (minimum 500 words with a maximum of two pages), and then the papers, must be sent to the Seminar Secretary. Deadlines: 15 September, 2000 deadline for abstracts 1 November, 2000 abstract acceptance 15 January, 2001 deadline for full-length papers At the seminar, all the participants will have a copy of the abstracts and a compact disc containing the full-length papers. After the seminar, a full review process will select the papers to be published in the final proceeding volume.

This group will be created through a recent initiative of the state of Lower Saxony. The salary will be according to BAT Ia. In addition to the head, the young researchers group will have one postdoc position according to BAT IIa and two Ph.D. student positions according to BAT IIa/2. Within a five year period the objective of the group will be to develop new numerical methods for the solution of inverse problems for partial differential equations, in particular for three-dimensional inverse scattering problems and related problems. This research will include both the theoretical foundations and the numerical implementation of the methods including tests with real data arising in applications. Fur further details see also http://www.num.math.uni-goettingen.de/kress/nachwuchs.html We expect applications from candidates who have the qualifications to guide and supervise both pre and post doctoral level researchers, including the ability to develop research contacts with institutions interested in applications, to effectively present the results of the group within the scientific community, and to obtain outside funding. For further qualification, i.e., for habilitation, the holder of the position will have to teach and to participate in the guidance of Diplom and PH.D. students in the Mathematische Fakultät. Applications including a curriculum vitae and a list of publications should be sent to the Director of the Institute by 15. Juni 2000 The University of Göttingen aims at increasing the proportion of women within its scientific personnel and therefore explicitly asks qualified women to apply. In case of equivalent qualifications, women will be given special consideration. In case of equivalent qualifications, handicapped applicants will be given priority.

The examples, in general, depend on certain parameters, whose values are chosen by the author of the paper. A reader may be interested in studying the examples for other parameter values, but typically this is not straightforward. Computer programs may have to be written or requested from the author of the paper. The Electronic Transactions on Numerical Analysis (ETNA) makes it possible to publish interactive examples that allow readers to vary parameter values. Presently, two papers J. Baglama, D. Calvetti and L. Reichel, Fast Leja points, ETNA 7 (1998), pp. 124-140, R. S. Varga and A. Krautstengl, On Gersgorin-type problems and ovals of Cassini, ETNA 8 (1999), pp. 15-20, illustrate this feature. Click on the ``interactive supplement'' for these papers for a demonstration. Authors of papers accepted for publication in ETNA are encouraged to supply interactive examples. The ETNA staff will assist with the design and Java programming of the examples. ETNA is available at http://etna.mcs.kent.edu and at mirror sites. In addition volumes 1-10 of ETNA are available on a new CDROM. The ETNA CDROM contains papers published in ETNA 1993-2000, interactive examples, a search engine and web browsers. A limited number of CDROMs are available for $10 each. Please send e-mail to etna@mcs.kent.edu if you would like your own portable copy of ETNA on a CDROM. ------------------------------ From: Hans Schneider Subject: Special Issue of Linear Algebra and its Applications Date: Wed, 10 May 2000 Linear Algebra and its Applications Special Issue on STRUCTURED AND INFINITE SYSTEMS OF LINEAR EQUATIONS Deadline extension The scope of the 'Special Issue on 'Infinite Linear Systems of Equations finitely specified' with deadline June 1st has been slightly extended to include very large structured systems and methods that may lead to the treatment of infinite systems. There have already been submissions to the previously announced special issue which fit the extended scope. We wish to give all potential authors the chance to submit papers fitting the broader scope and are therefore extending the deadline for submission to August 31st. The new, slightly adapted description of the special session reads as follows: One of the traditional hunting grounds of linear algebra is the area of finite systems of linear equations, as described by a matrix equation $Ax = b$. Here $A$ is a known matrix, $b$ a known vector of finite dimensions, and $x$ is an unknown vector of finite dimensions, which is to be determined such that the equation is either satisfied, or, if that is not possible, approximately satisfied. Many techniques are known for finding solutions or approximate solutions, depending on the properties of the given data and the approximation technique choosen. If the system of equations is not finite, i.e. $A$ is not a matrix but an operator, and $b$ and $x$ are of infinite dimension, then algebraic and numerical techniques can still be used provided the given data are finitely specified. Operators with such a property are often called 'structured operators', and it turns out that one can solve such infinite equations in an exact or approximate sense using finite methods and algorithms. Also in the case of very large structured matrices, methods can be devised that are in principle extendable to the infinite case. The conjunction of linear algebra and inversion theory for finitely specified infinite operators brings interesting connections to the forefront: algebraic equivalents of inner-outer factorizations e.g., or the algebraic significance of Kalman filtering. Structured matrices can be of many types, e.g. systems with finite displacement ranks or time-varying systems with state spaces of finite dimensions and whose limiting behaviour is known, e.g. as a time invariant system. A non-limiting list of topics of interest in this area is (assuming $A$ is an infinite but finitely described operator of some kind): - inversion methods - decomposition methods for the operator A - quadratic approximation methods - complexity reduction - equivalencies - canonical forms - transform techniques. Examples of operator structure: - systems with low displacement rank - finitely described time-varying systems - finitely described almost-periodic systems - differentials of non-linear systems. Interested authors are kindly invited to submit full papers with significant contributions to this area to any of the three guest editors listed below before August 31st, 2000.
