Jensen Soren S. Jensen 1956-1997 This is to announce the sudden and untimely death of Soren Jensen on Sunday, Feb 2, 1997, from a heart problem. He was 41. He is survived by his wife Pauline, and his three daughters, Elizabeth, Serina and Natasha. Soren received his Ph.D. from the University of Maryland, College Park, in 1985, under the guidance of Ivo Babuska. After graduating, he joined the faculty of the Department of Mathematics and Statistics, University of Maryland Baltimore County, where he was promoted to Associate Professor with tenure in 1992. Besides being an accomplished and well-known researcher in the field of finite element methods, with over thirty articles to his credit, he was also one of the Department's best and most popular teachers. Friends, colleagues and students will miss his dependable smile, his sunny personality, his wit and intelligence, his broad and far-reaching mathematical knowledge, his patience at explaining things, and the many other unique and wonderful qualities that made him so universally well-liked.

Here is the information file that all new subscribers get sent to them... --Ron NA-TEACH is an internet mailing list devoted to the discussion of the teaching of NUMERICAL ANALYSIS. Though it is intended to be a list devoted to teaching in an undergraduate setting, it is not restricted to this. Regular topics on NA-TEACH could include: a discussion of new Numerical Analysis textbooks, broadcasts of URLs where documents on numerical analysis can be found, personal reports on teaching numerical courses at your institution, impact of technology on the teaching of numerical analysis, curriculum debates, reform of numerical analysis courses, etc etc. There is a related list, called NA-NET, run out of the Oak Ridge National Labs, which is reached at na-net@ornl.gov or http://www.na-net.org/ which NA-TEACH evolved from. NA-TEACH will *not* be a moderated list. If people are interested in a moderated list then I will gladly accept volunteers to be the moderator. I will start it off as an UN-DIGESTED list, but will make a DIGEST available, if people request it. List Arrival: To join the NA-TEACH mailing list, send a message to MAJORDOMO@abacus.oxy.edu with one line in the message body SUBSCRIBE NA-TEACH List Departure: To leave the NA-TEACH mailing list, send message to MAJORDOMO@abacus.oxy.edu with one line in the message body UNSUBSCRIBE NA-TEACH List Posting: To post to the NA-TEACH mailing list send a message to NA-TEACH@abacus.oxy.edu Please note that the list is maintained by Majordomo 1.92, a sophisticated program written in Perl 4.036a. Most list functions are automated. Do not attempt to send non-command oriented messages to Majordomo. It will seimply reject them. It will also reject any commands in the Subject: field. If you have questions about lists of commands, email majordomo@abacus.oxy.edu the command HELP. Any other questions about the list should be sent to NA-TEACH-approval@abacus.oxy.edu or Majordomo-Owner@abacus.oxy.edu You can get a copy of this message by emailing the command INFO NA-TEACH to the Majordomo@abacus.oxy.edu address.

In particular I would like to know if a homotopy method is the best. The specific problem is a standard one: to calculate the induced norm of a matrix given the unit ball of the vector norm. In other words assume the following are given: A matrix M, and a unit ball B (in R^n) which defines a vector norm: ||x||=1 if x is on B. Find max ||Mx|| while x is restricted to B.

Can someone forward me a pointer to current information on this system. I am also interested in pointers to competing systems.

K. Godunov (Institute of Mathematics, Russian Academy of Sciences, Novosibirsk, Russia) will receive an honorary degree from the University of Michigan. Preceding the ceremony a symposium will be held on Godunov-type numerical methods, which are widely used to compute continuum processes dominated by wave propagation. The symposium will have international participation; it will bring together senior researchers who are experts in the development and use of Godunov-type methods, junior researchers who are currently making significant contributions in this field, graduate students just entering the field, and other interested individuals. The scientific part of the symposium starts with an overview of Prof. Godunov's most influential work in applied and numerical mathematics, and its impact on science and engineering, presented by one of the local faculty. In the following three sessions of half-hour talks, invited speakers from diverse disciplines will lay a link between his work and powerful methodologies currently in use in Computational Fluid Dynamics (CFD) and other computational fields. The three sessions of presentations will provide the symposium participants with a colorful and broad image of the state of computational science. In turn, this will serve as the basis for three end-of-session panel discussions on ``Current and Future Directions in Computational Science,'' lending a workshop character to the meeting. At some point Prof. Godunov will address the conference with an account of the earliest developments in CFD in Russia, developments in which he was personally involved. Chairperson of the Symposium is Prof. Bram van Leer (Aerospace Engineering).

Ischia, Italy 4 - 6 June 1997 H P S N O 97 The Conference, which is planned to be organized biennially, follows the HPSNO95 Conference that was held in June 95, and whose main contributions were published in a special issue of Computational Optimization and Applications. Putting together the recent progress in computer technology with the latest algorithmic developments in the field of numerical optimization represents an exciting challenge for researchers and an interesting opportunity for dealing with very large ``real life'' problems. The focus of the conference is to cover the latest results in optimization software and, in particular, optimization software for high performance computers. The conference will provide an overview of the nonlinear optimization field, including algorithms, software evaluation, implementation issues, applications and ture areas of research through autoritative lectures given by some of the most active researchers in the field. The Conference aims to promote research activities and cooperation among scientists in the field and therefore it will provide ample opportunity for informal exchange of ideas among researchers. The Conference will include lectures given by guest speakers and by authors of selected contributed papers. The list of invited speakers includes: C. H. Bischof, Nick Gould, W. Hager,J.J. More', P. Pardalos, M.C. Resende, P.L.Toint, M. Wright.
