Subject: New Edition of Braess Book on Finite Elements

I am pleased to anounce the second English edition of my book

"Finite Elements. Theory, Fast Solvers
and Applications in Solid Mechanics".
Cambridge University Press 2001 (April)
ISBN: 0 521 01195 7

We will mention some new material from the 2001 edition.
"Solutions of selected problems" from this book are placed
on my web page. The series will be enlarged on request.
Hints to some updates and to misprints (if necessary) will be
given in due time also on my web page

The introduction of finite element spaces in Chapter II, Section 5
is now focused such that all the ingredients of the formal
definition at the end of this section are well motivated.
There are now more details of the interpolation operators of
Clement type.

The general considerations of saddle point problems in
Chapter III are augmented. The direct and converse theorems that are
related to Fortin interpolation are presented now under a common
aspect. Mixed methods are often connected with a softening of
the energy functional that is wanted in some applications for good
reasons. A different but equivalent variational formulation
that has become popular in solid mechanics, is easily understood.

In Chapter IV only the (already short) standard proof of the
Kantorowitch inequality has been replaced by a shorter one.
The monotonicity of the function t+(1/t) for t>1 and Young's inequality
are sufficient.

The multigrid theory requires less regularity assumptions
if convergence with respect to the energy norm is considered.
A quick introduction into that theory is now included,
and multigrid algorithms are also considered in the framework
of space decompositions.

Finite element computations in solid mechanics require often
appropriate elements in order to avoid an effect called "locking"
by engineers. From the mathematical point of view we have problems
with a small parameter. Methods for treating nearly incompressible
material serve as a model for positive results while negative results
are easily described for a more general framework.

Subject: Seminar in Leipzig on Multigrid

Dear colleagues,

I'm very pleased to announce the

18th GAMM-Seminar Leipzig on
Multigrid and related methods for optimization problems
January 24th to 26th.

Chairmanship: Wolfgang Hackbusch (Leipzig)
Michael Griebel (Bonn)
Location: Max-Planck-Institute
for Mathematics in the Sciences,
Leipzig, Germany.

The first fifteen GAMM-Seminars were held in 1984, 1986-1999 at
the Christian-Albrechts-University to Kiel under the title
Annual GAMM-Seminar Kiel.
Since 2000, the GAMM Seminars have taken place at the
Max-Planck-Institute for Mathematics in the Sciences in Leipzig,
Germany, under the title Annual GAMM Seminar Leipzig.

Subject: Conference in Newport Beach on Cluster Computing

The IEEE International Conference on Cluster Computing
Sutton Place Hotel, Newport Beach, California, USA
Oct. 8-11, 2001

Sponsored by: The IEEE Computer Society, through the Task Force on
Cluster Computing (TFCC:

The rapid emergence of COTS-based Cluster Computing as a major strategy
for delivering high performance to technical and commercial
applications is driven by the superior cost effectiveness and
flexibility achievable through ensembles of PCs, workstations, and
servers. Cluster computing, such as Beowulf class, SMP clusters, and
ASCI machines is redefining the manner in which parallel and
distributed computing is being accomplished today and is the focus of
important research in hardware, software, and application development.

This year, for the first time, Cluster 2001 merges five popular
professional conferences and workshops: IWCC, PC-NOW, CCC, JPC4 and
German CC into an integrated, large-scale, international forum to be
held in Northern America. Last year's conference, IEEE Cluster 2000,
was held in Chemnitz, Germany.

The program includes an introduction by Thomas Sterling (Caltech/JPL),
keynotes by Steve Oberlin (Unlimited Inc), Hans Zima (University of
Vienna), and Charles Seitz (Myricom), over 46 invited and contributed
papers, three panel sessions, a poster session, an exhibition, and six
tutorials. Additionally, several social events are planned, including
a banquet on the Queen Mary in nearby Long Beach.
