Subject: Happy Birthday Victor Pereyra

Dear Friends,

December 26 is Victor Pereyra's 65th birthday.
Victor has made many contributions to numerical analysis through his work
which covered many areas such as being a leading figure in deferred
corrections and developing salgorithms for solving Vandermondes,
non-linear least squares, two point bouundary value problems, etc.

In addition, he was very much responsible for the development of numerical
analysis in Venezuela. He has mentored many South American
scientists. Victor continues to work very actively in many areas in NA.

So thanks for all your many contributions. And thanks for all your work
for the community done with humility and humor.

Subject: Lagrange Prize in Continuous Optimization

The Lagrange Prize in Continuous Optimization
Call for Nominations

Nominations are invited for the newly established Lagrange Prize in
Continuous Optimization, awarded jointly by the Mathematical
Programming Society (MPS) and the Society for Industrial and Applied
Mathematics (SIAM). The Prize will be presented for the first time at
the XVIIIth International Symposium on Mathematical Programming in
August 2003.

To be eligible, works should form the final publication of the main
result(s) and should be published either (a) as an article in a
recognized journal, or in a comparable, well-referenced volume
intended to publish final publications only; or (b) as a monograph
consisting chiefly of original results rather than previously
published material. Extended abstracts and prepublications, and
articles published in journals, journal sections or proceedings that
are intended to publish non-final papers, are not eligible. The work
must have been published during the six calendar years preceding the
year of the award meeting.

Judging of works will be based primarily on their mathematical
quality, significance, and originality. Clarity and excellence of the
exposition and the value of the work in practical applications may be
considered as secondary attributes.

Full details and prize rules are given at

http://www.mathprog.org/prz/lagrange.htm

To nominate a publication for the prize, please send a copy of the
paper and a letter of nomination by February 28, 2003 to the following
address.

Subject: Postgraduate Research Positions in Oslo, Norway

The Department of Scientific Computing at the Simula Research
Laboratory (www.simula.no/sc) in Oslo, Norway, invites applications
for two research positions in scientific computing at the postdoc or
research scientist level. The Laboratory is funded by the Norwegian
government with the purpose of performing long-term basic research in
the computing sciences. The Department of Scientific Computing runs
two fairly large projects, one regarding simulation of the electrical
activity in the human heart and the other on generic tools for coupled
problems (multi-physics simulation). Both projects focus on finite
element methods and software for partial differential equations as
well as mathematical/numerical studies and verification of
implementations. The Simula Research Laboratory has a very close
collaboration with the Norwegian universities and hosts many
university professors.

The successful applicant would preferably have a PhD in scientific
computing, computational mechanics, computational science and
engineering, numerical analysis, applied mathematics, or related
areas, with emphasis on computing and software development. The
ability to initiate and write scientific papers is considered very
important.

Background topics of particular relevance for the positions are
coupled PDE problems, bioengineering PDE models, Navier-Stokes
equations, thermal convection, parallel computing, adaptive methods,
multigrid and domain decomposition methods, design and verification of
numerical software, C++, Diffpack (www.diffpack.com) and Python
programming.

The positions are for a period of two years. To apply, please submit a
curriculum vitae, a list of publications, a brief description of
research interests, and the names and contact information for three
references. The application deadline is February 1.
