Subject: Updating Cullum and Willoughby Books on Lanczos Algorithms

Dear Colleagues,

In 1985 Birkhauser-Boston published a two-volume book,
Lanczos Algorithms for Large Symmetric Eigenvalue Problems,
Vol. 1, Theory: Vol. 2, Programs, by Ralph Willoughby
and me which contained the algorithmic work on large
scale symmetric eigenvalue problems which we had completed
prior to 1984. (Follow-on work by us on symmetric and
nonsymmetric algorithms is available in the literature).

Volume 1 focussed on the theory behind these methods.
Volume 2 contained vanilla Fortran codes implementing
most of the algorithms which were discussed in Volume 1.

Each algorithm was based upon a variant of a Lanczos
tridiagonalization recursion. Algorithms for real
symmetric, generalized real symmetric, Hermitian, singular
value, and complex symmetric problems were developed.
The block Lanczos algorithms invoked an implicit deflation
of the Lanczos vectors which was achieved by reorthogonalization
w.r.t. certain well-chosen vectors. However, the 'single-vector'
algorithms functioned with no reorthogonalization of the Lanczos
vectors and thus could be used on huge problems.

This book has been out of print for more than 10 years
but is still referenced frequently in the computational
chemistry and computational physics literature.

Therefore, my intention is to make this book available
for 'free' for downloading from my LANL web site which
is currently under construction:

Doing this requires manual conversion of the original
'script' files for the book and thus gives me the
opportunity to correct any errors which any of you
may have encountered in the book. I would also like
to compile an updated bibliography of related work
which has appeared since 1984.

This note is to ask for your input w.r.t

(1) any errors which need to be corrected

(2) any appropriate new citations
(An annotation which summarizes the contribution in the
work cited would be greatly appreciated)

(3) the existence and availability of any updated versions
of the codes which are currently available from Netlib under
the heading 'lanczos'.

My intention is to also make all of the codes with listings
in Volume 2 available via Netlib.

Please send your input to using
the subject heading 'Lanczos Book'. If it is
easier to fax your input to me, my fax number
is 505-667-1126. I would appreciate
receiving your input before August 30th. However,
material received later than that date will also
be appreciated.

Thank you very much,

edited by C. A. Floudas & P. M. Pardalos

Kluwer Academic Publishers, Dordrecht
Hardbound (6 volumes), ISBN 0-7923-6932-7, June 2001, 3200 pp.

Optimization problems are ubiquitous in the mathematical modeling of real
world systems and cover a very broad range of applications. These
applications arise in all branches of Engineering, Computer Science,
Economics, Finance, Operations Research and Management Science,
Chemistry, Materials Science, Astronomy, Physics, Structural and Molecular
Biology, and Medicine.

The Encyclopedia of Optimization aims at serving as an important
reference for all parts of optimization. It is directed to a diverse audience of
students, scientists, engineers and in general to any decision maker and
problem solver in academia, business, industry, and government who is
concerned with aspects of optimization theory, algorithms, and applications.

There are two main types of articles in the Encyclopedia of Optimization.
The first type consists of survey-expository type articles regarding various
topics of optimization of general interest. The second type contains more
detailed concrete problems, techniques, or applications. The Encyclopedia of
Optimization also contains articles that provide historical perspectives and
selected biographical entries.

All articles provide an introduction and motivation for the subjects, present
the important contributions and illustrations, and contain a list of references
that can be used as pointers for more detailed information on the subject.
Besides the five volumes of articles, a separate volume of a cumulative index
with thorough cross-referencing is provided that can serve as a useful tool of

Subject: Wavelets for Undergraduates at San Diego AMS Meeting

Ed Aboufadel and Steve Schlicker are organizing a special session on
Wavelets for Undergraduates at the San Diego meeting of the AMS, January
6-9, 2002. We are able to schedule as many as seven 20-minute talks. If
you are interested in presenting at the session, please respond to this
message by August 15, 2001. If possible, please include a short abstract
of your proposed talk. (Final abstracts are not due until September.)

Description: For more than a decade, there has been much excitment and
creativity surrounding the subject of wavelets. This is due, in part, to
known and potential applications of this tool from analysis. Although
research on the subject has been at the doctoral level, wavelets are quite
accessible to undergraduates, given its connections to linear algebra.
The past few years have seen books and articles on wavelets written for
undergraduates, along with NSF-sponsored Research Experiences for
Undergraduates programs for which wavelets were a topic of research. The
goal of this special session is to bring together researchers and
educators to share their experiences of work done with wavelets by

Subject: SCAN 2002 Conference

SCAN 2002
10th GAMM - IMACS International Symposium
on Scientific Computing, Computer Arithmetic, and Validated Numerics
Paris, France
September 23 - 27, 2002

The conference continues the series of international SCAN symposia,
which have been initiated by the University of Karlsruhe. At the
beginning, the symposia have been held in this town, but with its
increasing interest SCAN symposia have been held in many towns in
Europe: Basel (1989), Varna-Albena(1990), Oldenburg(1991), Wien(1993),
Wuppertal(1995), Lyon (1997), Budapest (1998), Karlsruhe(2000), under
the joint sponsorship of GAMM and IMACS. These conferences have
traditionally covered the numerical and algorithmic aspects of
scientific computing, with a strong emphasis on validation and
verification of computed results as well as on arithmetic,
programming, and algorithmic tools for this purpose. The objectives
are to propagate current applications and research as well as to
promote a greater understanding and increased awareness of the subject
matters. With the increasing power of computers, many complex
numerical simulations requiring a great lot of computations are now
performed. It appears more and more necessary to validate results
obtained with the finite arithmetic of computers. Many researches
concern the validation using a deterministic approach as computer and
interval arithmetic, specific verification methods, probabilistic
approaches as discrete stochastic arithmetic, etc. Tools are now
proposed to users, which are able to conclude that results provided by
computers are reliable, even if much work remains to be done in this
field. Other tools for validation and avoiding round-off errors are
based on exact representation and computer algebra systems. It seems
that the future development of the field will be seeked in the
combination of various approaches and existing tools. One of the
missions of SCAN 2002 is to become a forum for the presentation of the
many existing validation tools and approaches in order to meet
representative populations of these various fields and uniform their

The scientific program will consist of invited general lectures and
contributed presentations. Exhibitions and demonstrations of computer
hardware and software will be welcome.

Subject: Workshop in Bramen on Computer-aided Control Systems Design

Second announcement and call for posters
Workshop and training course
September 27-29, 2001, University of Bremen, Germany


With the ever-increasing complexity of control systems, efficient
computational methods for their analysis and design are becoming more and
more important. These computational methods need to be based on reliable
and robust numerical software provided by well-tested and user-friendly
software libraries.

This workshop and training course is intended as a tutorial on the use
of the freeware Subroutine Library in Systems and Control Theory (SLICOT)
for solving practical control engineering problems within computer-aided
control systems design (CACSD) environments. SLICOT-based software
usually has improved reliability and efficiency as well as extended
functionality compared to the computational methods implemented in other
CACSD software packages.

Some of the world's leading experts in the field of computational methods
in CACSD will introduce SLICOT-based software to be used either within
Matlab and the Matlab Control Toolbox or the CACSD package Scilab.

The course includes hands-on training during which participants will
solve practical problems in control systems design using this software.
Major topics of the course are

* basic control software
* system identification
* model reduction
* robust control design using H-infinity techniques

During the poster session participants will have the opportunity to
present their own projects and to discuss current problems or open

Subject: Postdoctoral Position at Naval Research Laboratory

Research in Data Assimilation

The Naval Research Laboratory at Stennis Space Center, MS is
searching for a postdoctoral candidate for research in data
assimilation. Present postdoctoral salary is $53,000 per year.
Some background information on projects at NRL Stennis may be found at:

Inquiries may be directed to:

Gregg Jacobs
NRL Code 7323
Stennis Space Center, MS 39529 USA
(228) 688-4720

NRL is beginning to move into the area of advanced data assimilation.
Present emphasis is on 4-D Var using adjoint and representer methods,
though evaluation of Kalman filter/smoother methods along with direct
minimization of cost functions is desired. These assimilation systems
will be applied to short time periods (order of 1 week) to regional
areas (order of 100x100 km square) with boundary conditions provided by
larger scale models. At these time periods and scales, direct
assimilation of inertial oscillations is of importance. Our interests
are to understand how the dynamics in continental shelf regions
propagate information from measurement as well as how various
measurement types (velocity throughout the water column, velocity at
the surface, sea level, ...) affect a posteriori error estimates.
Advanced data assimilation at NRL is in a formative process. This is
an excellent opportunity for a successful postdoctoral applicant to
help direct the future work and take advantage of the observational and
modeling capabilities at NRL.
