Subject: Looking for Book 'Approximate Methods of Higher Analysis'

To: readers of na.digest --

I would like to buy a copy of the book 'Approximate Methods of Higher
Analysis' by L.V. Kantorovich and V.I. Krylov (translated by C.D.
Benster) published by Interscience in 1958. It is now out of print.
Please contact me if you have a copy to sell.

FYI: If you have access to the World Wide Web [WWW], you may want to
have a look at the DESY Entry Point to WWW (accessible e.g. from
the HEP Overview Page). Under "Documents provided by Users", you'll
find a link to "C++ for HEP applications". There I have collected
a couple of documents: the summary of the 1992 SIAM workshop
"Scientific Computing with C++" may find your particular interest.

The WWW address for the C++ Page is:

http://x4u.desy.de:80/gnu/ftp/pub/www/projects/hepC++.html

Accessible e.g. from the DESY Home Page at

http://x4u.desy.de:80

If you dont know what WWW is, but you have got a telnet server, try

telnet info.cern.ch

this brings you to the WWW Overview Page at CERN (simple line mode [*])
from where you reach the links "HEP" -> "DESY" -> "C++".

There, you will also find preliminary information on work in
progress on a C++ Class Library for MultiGrid Programming which I hope
to finish by this summer. In my own field, large-scale computations in
lattice field theory, there have been similar approaches based on
C (the CANOPY tool set) and APESE (language on the dedicated APE-100)
for grid-applications.

The only only example where I have directly compared C++, C and FORTRAN
are Multigrid applications. Here, C++ is conceptually clearly superior to
FORTRAN [see the summary report mentioned above, and related papers by U.
Ruede, available via anonymous FTP from casper.cs.yale.edu as
mgnet/papers/Ruede/data_struct.ps.Z and
mgnet/papers/Ruede/programming.dvi.Z].

As for speed, you have to pay a price for some additional
structures, both for storage and CPU (e.g. virtual functions);
depending on this choice of structures (but also on your environment:
C++ compiler or C++ Cfront, scalar/vector/parallel machine...) I have
heard estimates of 5-20% overhead (which is quite a gap). Since
optimization is usually the last step or program development, I
cannot give reliable numbers yet.

As for stability, though there is no ANSI standard yet, C++ has
become a quasi-standard OOP tool (which is often criticised) which I
have found to be sufficiently stable in practical work (same is true
for the differences between compilers -- on fast machines, I have
used a CRAY Cfront and GNU g++ so far). Based on work in the
standardization committee, many a set of "coding rules" has evolved, and
several libraries are already available (though I dont have
experience with any of them). All this information is on the net
(comp.std.c++,comp.lang.c++) or on the World Wide Web [see above].

I'd like to know if you have problems accessing the documents on the
Web.

Hope this helps--

Subject: New Book on Probability and Approximation Theory

Pitman Research Notes In Mathematical Series
"Moments in probability and approximation theory"
George A. Anastassiou

The use of probabilistic methods in other mathematical disciplines
has become a trend in recent years, since they produce simple and
elegant proofs usually leading to optimal results. This research
monograph in approximation theory and probability theory falls into
this category. Using methods from geometric moment theory, the
author first solves some very important basic moment problems, and
then develops in parallel the theories of convergence of positive
linear operators to the unit/weak convergence of finite measures to
the Dirac measure, both with rates. The results produced are
quantitative inequalities and most of them are either sharp or
nearly sharp. Many examples connecting the material to other
topics are given.

Readership: Researchers in approximation theory, probability
theory, numerical analysis, statistics, applied analysis, classical
analysis, measure theory, functional analysis, and related fields.

Subject: Free Books/Software

We have decided to give away some lecture notes and software that
we've written over the years. More is in the works and we hope
that others will join us in making their works available for all
to share. None of the authors, the Colorado School of Mines, New
England Research, or anyone else you can imagine makes any prom-
ises or guarantees about anything in these documents/codes.

If you want any of this material, here's what you do. Ftp to the
Internet site hilbert.mines.colorado.edu (138.67.12.63) and log
in as anonymous. Any password will do. Dir doesn't work here so
you need to use ls (or mls if you're coming in from abroad). CD
to pub and you will see, among other things, the following direc-
tories:

papers
uga

Directory uga contains a preliminary release of UGA (uni-
processor genetic algorithm) and associated class libraries. The
code was developed on Sun Sparcstations using AT&T's C++ com-
piler. Versions which will compile using the GNU C++ compiler on
various architectures are in preparation.

The lecture notes are in directory papers. Subdirectories in-
clude:

migration
conjugate_gradient
theoretical_seismology

What you will see in these directories are compressed postscript
files. Migration contains lecture notes for a graduate course in
seismic imaging. It's about 200 pages long and has roughly 55
figures.

Conjugate_gradient contains notes for a short course on the use
of sparse matrix methods for inverse calculations. About 40
pages with no figures--yet.

Theoretical_seismology contains lecture notes for a graduate
course in theoretical seismology. About 120 pages with a few
figures. We expect that many figures will be added in the next
few months or so, at which time we'll put out a revised version.

So, there you have it. If you have any books, lecture notes or
software that you would be willing to distribute freely, drop us
a line and we'll be happy to include your contribution. And
remember, you get what you pay for: please don't send any irate
email asking how you get from equation 8.4.6 to 8.4.7 on page so
and so of some document.

Subject: Conference on Domain Decomposition

2nd Call for Papers and Registration Information

SEVENTH INTERNATIONAL CONFERENCE ON
DOMAIN DECOMPOSITION METHODS IN SCIENTIFIC AND ENGINEERING COMPUTING

Keller Conference Center
Pennsylvania State University
University Park, Pennsylvania

October 27--30, 1993

ABOUT THE CONFERENCE:

Domain decomposition refers to a class numerical methods for obtaining
solutions of scientific and engineering problems by combining solutions
to problems posed on physical subdomains, or, more generally, by
combining solutions to appropriately constructed subproblems. It has
become a subject of intense interest recently because of its
suitability for implementation on high-performance computer
architectures. The aim of this conference, and of similar gatherings
in the series, is to bring together researchers with different
backgrounds working in this active area to discuss recent and
prospective advances and to promote interaction among applied
scientists, computer scientists, and numerical analysts.

FORMAT AND THEMES:

The conference will feature invited lectures, selected contributed
papers and poster presentations. Themes of the conference will range
from basic theoretical research to industrial applications related to
domain decomposition (DD) method, including:

numerical analysis of DD methods
block and substructuring methods
multigrid and multilevel methods
fictitious domain methods
DD methods for high order and spectral methods
DD methods for nonlinear and time dependent problems
DD methods in computational fluid dynamics and structural mechanics
graph decomposition
general iterative and preconditioning methods
parallel implementations
software developments

CONFERENCE PROCEEDINGS:

The conference proceedings will be published by the American
Mathematical Society in the series Contemporary Mathematics. Refereed
papers from both invited and contributed talks may appear in the
proceedings.

CONTRIBUTED PAPERS:

Potential contributors should submit an abstract of no more than one
page by May 15, 1993 to the conference secretary at the address below.

The submission of the abstract through e-mail is preferred. Plain TeX,
AMSTeX and LaTeX are all welcome and sample tex macros are available
