Subject: Non-Product 2D Box Integration Quadrature

I am looking for a program that calculates non-product quadrature weigths and
absisas for 2D box numerical integrals. Preferably of the Jenkins type or


Q = A f(0,0) + B [ f(r,-s)+f(-r,s)+f(-r,-s)+f(r,s) ] + C [
f(u,-v)+f(-u,v)+f(-u,-v)+f(u,v) ]

where A, B, C, r, s, u, and v are constants.

Subject: Request for a Complex Matrix Diagonalization Subroutine


For our quantum chemistry calculations we need a fast complex matrix
diagonalization routine. The matrices are not sparse and their dimension
is ~10^2. Fortran highly preferred.
Could you kindly send an answer back to my e-mail address ?

Subject: CWI Survey Paper, Time Integration for Air Pollution Models

CWI SURVEY: Time Integration for Air Pollution Models

Air pollution modelling gives rise to stiff systems of
of advection-diffusion-reaction equations in 3D. Due to the
large number of chemical species, off-the-shelf stiff
ODE integrators are not feasible for the numerical time
integration. This has led to the use of special time
integration techniques. Keywords are stiff chemistry
solvers, positive advection schemes, operator splitting,
implicit-explicit methods, approximate matrix
factorization techniques, etc. With Joke Blom and Willem
Hundsdorfer I have written a survey paper on this subject.
The paper also addresses HPCN aspects typical for
large-scale reactive flow type problems.

The paper (2006 K, 58 pages) can be downloaded from (paper 31).

Subject: Course on Interval Arithmetic

Intensive Tutorial Course


Responsible Organizer
Dr. Josep Vehi, Universitat de Girona

Prof. J. Garloff, University of Applied Sciences, Konstanz, Germany.
Prof. V. Kreinovich, University of Texas at El Paso, USA.
Prof. B. Barmish, University of Wisconsin at Madison, USA.

22-23 February 1999, Universitat de Girona, Girona, Spain.


In coincidence with the workshop MISC'99 to be held on 24-26 February
1999 in Girona, a pre-workshop tutorial course "Introduction to interval
arithmetic and its applications" will be organized by the University of
Girona. The aim of the course is to bring together researchers and
doctorate students that work in systems and control engineering so as to
give them the opportunity to have a knowledge of the method of intervals
and to stimulate discussion of relevant problems and fertile lines of
future research.

Three prominent speakers, Professor J. Garloff, Professor Vladik
Kreinovich and Professor Bob Barmish, will provide an interesting and
comprehensive state-of-the-art tutorial on motivations, basic theories
and applications of interval analysis to systems and control. The past
two decades have witnessed steadily increasing recognition and
appreciation of Interval Analysis in solving problems in systems and
control engineering. For instance, problems like analysis and synthesis
of robust controllers for uncertain plants or fuzzy interference have
been stated from the interval point of view. Recent developments have
generated a great deal of interests in emerging tools aimed at
exploiting qualitative, semiqualitative and interval simulation and
their application to fault detection and diagnosis and to system

Subject: Workshop on Computational Methods in Engineering


A one day workshop in Uppsala, Sweden, June 11, 1999

Challenging computational problems emerging in industrial
engineering applications continue to be a driving force in

computing. This is the rationale for organizing a workshop
focussing on Computational Methods in Engineering at the
Department of Scientific Computing, Uppsala University in
Uppsala, Sweden, in June. The following researchers
have accepted to give overview lectures.

Bjorn ENGQUIST, Royal Institute of Technology, Stockholm,
and Columbia University, New York.

Heinz-Otto KREISS, Royal Institute of Technology, Stockholm,
and UCLA, Los Angeles, California.

Robert W. MacCORMACK, Stanford University, Stanford, California.

Margaret H. WRIGHT, Lucent Technologies, Murray Hill, New Jersey.

There will be no contributed talks.

Professor Bertil Gustafsson at the department will celebrate
his 60th birthday in July, 1999. The day will end with a dinner
in his honor.

The registration fee for the workshop including coffee,
lunch and dinner will be 500 SEK (about 60 US$). Registration
will start at 9.00 on June 11. The lectures will start at 9.30.
More information about travel, hotel reservation and a
registration form are found at
This web page will be updated continuously. Questions can be
sent via e-mail to

Subject: Workshop on Computational Plasticity

Mathematisches Seminar,
Christian-Albrechts-University of Kiel, Germany,
August 27th to 29th, 1999

M. Brokate (Kiel),
C. Carstensen (Kiel),
B.D. Reddy (Cape Town).

The aim of the workshop is to provide a forum to discuss and
present aspects of the state of the art of the mathematical
foundations of computational plasticity. Topics range from the
mathematical theory of continuum models in plasticity, the
well-posedness of boundary and of initial-boundary value problems,
and their efficient discretization, including algorithmic aspects
in solution procedures.

Topics of interest include, but are not restricted to, the following:

o Mathematical analysis of (visco-) plasticity
o Well-posedness of (perfectly) plastic problems
o Numerical analysis of variational inequalities
o Computational (visco-) plasticity
o Numerical analysis of localization
o A priori error analysis
o A posteriori error analysis
o Adaptive algorithms for spatial and time-step discretization
o Coarsening and special adaptive strategies

Everybody interested in the topics of the symposium is warmly
invited to attend. Please let us know about your intention to
participate a.s.a.p. A second announcement with
further information, in particular, concerning hotel
accommodation, will be distributed in March, 1999.

Call for papers: Participants wanting to give a talk (20 min)
should submit an abstract before June 15, 1999.
Notification of acceptance will be given in July, 1999.

All correspondence in connection with the workshop, including
registration and submission of abstracts, is to be made via
e-mail on address:

Subject: Report on John Butcher Retirement Meeting


The Department of Mathematics at Auckland University was, over the
period December 14th -- 16th 1998, the venue for a meeting to mark the
official retirement of Professor John Butcher, FRSNZ announced in

For three days from 8.30 a.m. to about 6 p.m. the assembled
participants presented their talks at an average of about 10 per day,
as a tribute to John and to mark their respect for John, the scholar
and their affection for John, the man. In this those in New Zealand
were joined by about a dozen participants from other countries.
Tributes from non-mathematical New Zealanders included those from
Professor Sir John Scott (President of the Royal Society of NZ),
Professor Philippa Black (Acting Deputy Vice-Chancellor (Academic))
Professor Ralph Cooney (Dean of the Faculty of Science), Professor Rob
Goldblatt (President of NZ Mathematical Society) and, in absentia,
from Sir Ian Barker, Chancellor of the University. The University of
Auckland review of John's career was published at

The preliminary programme
had withheld the name of the opening speaker, a mystery guest who, it
transpired from the full programme
was, a surprise for John Butcher, your present correspondent.

With such an intensive programme of lectures as this, it would not be
possible to provide here a comprehensive review and do justice to
all. Suffice it to remark that within the programme there were nine
one-hour talks that ranged over Runge-Kutta theory, Dynamical systems,
ODES and Lie Groups, error estimation in ODEs, adaptive computation in
PDEs, differential equations with retarded arguments, etc. John
himself delivered a talk entitled "Beyond DESIRE", that (inter alia)
set out some of his ambitions for ongoing research. (Mathematicians
like John never really retire!)

The gathering provided an opportunity for social gathering, both at an
excellent dinner at Langton's Restaurant on Mount Eden and at a convivial
barbecue at the home of John and Jenny Butcher. For a selection of
pictorial images, see

The organising committee comprised Dr Robert Chan (Chair),
Prof. Marston Conder, Mrs Nicolette Goodwin, Mrs Bev Grove, and
Dr. Allison Heard. I believe that the quality of this well-organised
meeting and of the individual contributions were a clear indication of
the high regard in which John Butcher is held. The next meeting in the
ANODE Series will be held in Auckland on August 16th--20th 1999 (see following the
SciCADE99 meeting in Queensland (August 9--13th), see
