**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

"http://homepage.ruhr-uni-bochum.de/Dietrich.Braess/ftp.html"

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Kantorowitch inequality has been replaced by a shorter one.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.

of Computational Methods in Sciences and Engineering (JCMSE)", a newly

emerging interdisciplinary journal (see for more details the JCMSE's Web

Page: http://www.demon.co.uk/cambsci/jcmse.html).

Since a number of such copies is rather limited you are encouraged to

promptly order a free of charge sample of the first issue of JCMSE for

yourself, by simply sending an e-mail to the Publisher at:

**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**

IEEE CLUSTER 2001

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: http://www.ieeetfcc.org)

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.
