In addition to ongoing research, which will be partly interdisciplinary
between the areas mentioned, there will be an international visitors' program
in the form of special semesters on application fields.

The institute will be housed on the campus of the Johannes Kepler
Universit=E4t in Linz, a town of about 200.000 on the Danube, very close to
the Austrian Alps, and half-way between Vienna and Salzburg.

We are looking for PostDocs with a strong interest in one of the fields above,
who are also willing to work in an interdiscplinary environment; doctorate in
mathematics or a closely related field required.  In addition, we are also
looking for Senior Postdocs, who could lead a group and would also be expected
to attract additional funding; they should have a substantial publication
record beyond the doctorate.  The working language will be English.  The

From: Scott Hawley 
Subject: Multigrid with excision

I am looking for information on using multigrid with excision, i.e.  with both
inner outer boundary conditions.  (In my case, these boundary conditions are
both Dirichlet conditions.) Can you point me to any relevant references?  I
have not yet found any on MGNet or in my brief survey of the literature.

My problem is that I am finding a lack of proper (second-order) convergence in
my FAS algorithm, for cases in which the extent of the excised region has
different sizes on different levels of the multigrid hierarchy.  All I have is
hand-wavy argument that "the domain size is different on different grids", but
nothing serious.  I want to understand better what is happening.

Many thanks,
Scott Hawley

From: Jane Cullum 
Subject: Republication by SIAM of my book on Lanczos Algorithms

The Society for Industrial and Applied Mathematics (SIAM)
has republished Volume 1 of my book on algorithms for large
scale eigenvalue/singular value problems. Details are in the
message from SIAM which is included below.

W.r.t the codes which are mentioned in that message, we intend
to submit updated and parallel versions of some of those uni-processor
codes to NetLib for public distribution in the not too distant future.

Jane Cullum
cullumj@lanl.gov

                                  * * * * *

SIAM is proud to announce the publication of _Lanczos Algorithms for Large
Symmetric Eigenvalue Computations; Vol. I: Theory_, by Jane K. Cullum and
the late Ralph A. Willoughby in our Classics in Applied Mathematics series.

First published in 1985, this book present background material,
descriptions, and supporting theory relating to practical numerical
algorithms for the solution of huge eigenvalue problems. This book deals
with "symmetric" problems. However, in this book, "symmetric" also
encompasses numerical procedures for computing singular values and vectors
of real rectangular matrices and numerical procedures for computing
eigenelements of nondefective complex symmetric matrices.

This book continues to be useful to the mathematical, scientific, and
engineering communities as a reservoir of information detailing the
nonclassical side of Lanczos algorithms and as a presentation of what
continues to be the most efficient methods for certain types of large-scale
eigenvalue computations. An on-line version of _Vol. II: Programs_, which
contains the original FORTRAN code and documentation for each of the
Lanczos procedures discussed in Vol. I, can be found at the numerical analysis
community repository, www.netlib.org, under the term "lanczos."

Subject: 2nd Announcement of Vienna Winter School 01/2003

Vienna Winter School on the Mathematical Foundations 
of Computational Sciences

January 26 till February 8, 2003

at Vienna University of Technology, Austria,

Intention

Almost all kind of engineering applications involve numerical simulations to
guarantee their quality, durability or safety.  Behind the most frequently
employed software packages lies a discretization of a PDE, often a finite
element method.  In all those cases, there exist a discretization error which
can be small or large, of minor or dominating significance.

It is the aim of the Vienna Winter School on the Mathematical Foundations of
Computational Sciences to provide a direct introduction to reliable and
efficient computation and error control in numerical simulations.  The topics
range from elementary functional analysis (in the first week) to advanced
adaptive finite element techniques and applications (in the second week).

Students of Engineering and Natural Sciences with basic mathematical
background are welcome if interested in guaranteed convergence of their FE
schemes.

Amongst the invited lecturers are

Carsten Carstensen (Vienna University of Technology, Austria)
Simon Shaw (Brunel University, UK)
John R. Whiteman (Brunel University, UK)
Willy Dörfler (University of Karlsruhe, Germany)
Stefan A. Funken (FEMLAB, Germany)
Klaus Hackl (University of Bochum, Germany)
Kerstin Weinberg (Caltech, USA)

Please do not hesitate to contact us for any assistance on your travel
arrangements, accommodation reservations in Vienna, or any further questions.
The web site

From: Craig Douglas 
Subject: Quasi Free Fortran 95 and C/C++ Compilers for Linux

In V12N02, Dongwoo Sheen provided information about Intel's compilers for the
I32 and I64 class processors (Pentiums and Itaniums).  There have been two
major updates since then.  I found that the version 5.0 compilers were almost
impossible to install and run on Linux (either platform).  The latest version
7.0 installed seemlessly for me on my laptop (IA32), and my Itaniums (1 and
2).  After I deleted all references to environment variables, the compilers
just worked.

If you tried the compilers before and were frustrated (like me), please try
again.  I found the compilers produced coded several times faster than what
the GNU compilers produced for the Itaniums.

The quasi in the subject has to do with the license restrictions (academia,
etc.)

Subject: New Peat & Barley CD

Becky and I are excited to announce the release of our new Peat & Barley CD
"On the Brink"!  Peat & Barley is Bill Mitchell on hammered dulcimer and Becky
Ross on fiddle.

This collection of Celtic and original tunes ranges in mood from darkly
mysterious to playfully lighthearted and includes toe-tapping jigs and reels
as well as lyrical airs and waltzes.  Peat & Barley's intimate arrangements
highlight the interplay between the hammered dulcimer and fiddle - each
contributing structure and melody in turn.

Check out some samples from "On the Brink" by visiting our web page

or full length samples at the Washington Post mp3 site 

    http://mp3.washingtonpost.com/bands/peat_and_barley.shtml
or

    Editor's Note: Bill sent this to me and called it _s_p_a_m_.  Wait until he
    -------------  sees it here :-)  Contact him directly for more details.
