Subject: Archimedes Was Not An Idiot
In the idiosyncratic but delightful book "Real Computing made Real"
by Forman S. Acton (1996), there appears (p.172) under the heading
"ARCHIMEDES, DESPAIR!" the iteration
s_{n+1} = 2^n sqrt(2(1-sqrt(1-(s_n/2^n)^2)))
for n=2,3,... with s_2=2 sqrt 2
which in infinite precision converges to pi, but is numerically unstable.
The formula earlier appears (p.17) in another very pleasing book
"Essentials of Numerical Analysis" by Peter Henrici (1982), in a
discussion starting with the words "Following Archimedes ..." as
y_{k+1} = 2^(k+1) sqrt((1/2)(1-sqrt(1-(2^(-k)y_k)^2)))
with y_1=2, which gives y_k=s_k. Anyone who has seen what Archimedes
actually did (e.g. look at Heath's translation) will realize that
to attribute this grotesque and useless formula to the world's first
numerical analyst is a monstrous distortion. The original algorithm is
t_{k+1} = c_k + t_k
c_{k+1} = sqrt(1+t_{k+1}^2)
which gives
2^k n_0 / c_k < pi < 2^k n_0 / t_k
when started with t_1=sqrt(3), c_1=2, n_0=3. Elegant, simple and stable.
The question I pose to NA-netters is: who started this slander? Can 1982
really be the first year in which it appeared?

Subject: Software for Eigenvalue Problems Available
SLEPc: Scalable Library for Eigenvalue Problem Computations
http://www.grycap.upv.es/slepc
We are pleased to announce the release of SLEPc 2.1.5, a parallel
software library for the solution of large sparse eigenvalue problems on
parallel computers. It can be used for the solution of problems
formulated in either standard or generalized form, both Hermitian and
non-Hermitian, with either real or complex arithmetic.
SLEPc is built on top of PETSc, the Portable Extensible Toolkit for
Scientific Computation (http://www.mcs.anl.gov/petsc). It can be
considered an extension of PETSc providing all the functionality
necessary for the solution of eigenvalue problems. SLEPc includes
several eigensolvers as well as interfaces to other libraries such as
ARPACK. It also provides built-in support for spectral transformations
such as shift-and-invert.
This software should be considered as part of an ongoing project and we
plan to continue its improvement by adding more solvers and tools.
Please send bug reports, questions, and requests for new features to

New monograph from AMS:
Meromorphic Functions and Linear Algebra - Olavi Nevanlinna, Helsinki
University of Technology - AMS, 2003, 136 pp., Hardcover, ISBN
0-8218-3247-6, List: $49, All AMS Members: $39, FIM/18
The book shows how one can have perturbation theory for the
resolvent under low rank updatings. For example, if the spectrum of
a matrix collapses under such an updating, then necessarily the
eigenvectors become badly conditioned. This qualitative phenomenon
is made quantitative by measuring the resolvent as a meromorphic
function. Applications are given to Krylov methods and to power
boundedness.

Special Issue of Computational Statistics and Data Analysis
Matrix Computations and Statistics II
A number of interesting and important ideas have resulted from the
relationship between matrix computations and statistics. Well known examples
include the solution of least squares problems, computation of the singular
value decomposition and its generalizations, estimation of principal
components, computation of canonical correlations, several cluster analysis
algorithms, and the solution of total least squares problems.
A previous special issue on this area featured papers on multidimensional
scaling, an application to web search engines, an algorithm for seemingly
unrelated regression models, an error measurement model for motion analysis,
and a survey on alternating least squares problems. These papers left the
impression that the overlap between matrix computations and statistics is a
fertile area of research.
Thus we propose a second special issue on matrix computations and statistics
The editors would like to receive papers on any of the topics listed above
and also topics such as latent semantic indexing, structured total least
squares, cluster analysis, complete orthogonal decompositions, data compression,
linear discriminant analysis, dimension reduction/feature extraction, and
applications of statistical matrix computing to other scientific disciplines.

Subject: Special Issue of LAA on Matrices and Mathematical Biology
LINEAR ALGEBRA AND ITS APPLICATIONS
Special issue on Matrices and Mathematical Biology
Second call for papers
Submission deadline extended to 30 November 2003
In the last decade the field of mathematical biology has expanded very
rapidly. Biological research furnishes both data on and insight into the
workings of biological systems. However, qualitative and quantitative
modelling and simulation are still far from allowing current knowledge to
be organized into a well-understood structure. Further, the diversity
present in mathematical biology, coupled with the absence of a single
unifying approach, has inspired the formation of entirely new scientific
disciplines such as bioinformatics.
Theoretical research activity in mathematical biology is
naturally of an interdisciplinary character. It involves
mathematical and statistical investigations, sometimes in
combination with techniques originating from the computational
sciences. In many of these approaches, linear algebra is key to
solving the mathematical problems which arise. For instance, in
some population models, the asymptotic rate of increase of the
population turns out to be the spectral radius of a certain
matrix associated with the population, while the other
eigenvalues also yield information on the evolution of the
population's structure. Conversely, problems in mathematical
biology can enrich linear algebra. For example, in attempting to
measure the influence of a single matrix entry on a simple
eigenvalue, linear algebraists frequently employ the derivative
of that eigenvalue with respect to the entry. However, some
biologists have proposed the use of the elasticity, or a
logarithmic derivative, of an eigenvalue with respect to a matrix
entry in order to measure the effect on that eigenvalue of
perturbing a matrix entry. Thus linear algebraists are challenged
to deepen and develop the understanding of the ways in which the
effects of changes in the ecological conditions on the
populations can be measured through further theoretical
investigations.
A recent book by Caswell on matrix population models makes extensive use
of linear algebraic techniques. Quoting from the introduction to that
book: "Matrix population models -- carefully constructed, correctly
analyzed, and properly interpreted - provide a theoretical basis for
population models... A goal of this book is to raise the bar of what
constitutes rigorous analysis in population models.... The work of the
population biologist is too important to settle for less." But Caswell's
call for careful mathematical construction and analysis applies to areas
beyond the subject of population models; clearly a rigorous approach would
benefit all areas of interaction between biology and mathematics.
The Special Issue of LAA dedicated to Matrices and Mathematical Biology is
intended to both foster and accelerate cross fertilization between those
working primarily in linear algebra and those working primarily in
mathematical biology. The editors hope that such an issue of LAA will be
of benefit to both fields.
This special issue will be open for all submissions containing new and
meaningful results that advance interaction between linear algebra and
mathematical biology. The editors welcome submissions in which linear
algebraic methods play an important role for novel approaches to problems
arising in mathematical biology, or in which investigations in
mathematical biology motivate new tools and problems in linear algebra.
Survey papers which discuss specific areas involving the interaction
between biology and linear algebra, particularly where such interaction
has been successful, are also very welcome.
Areas and topics of interest for the special issue include, but are not
limited to:
metabolistic pathways
statistical data analysis
linear algebra problems in graph partitioning
matrix population models
model discrimination in biokinetics
linear algebra problems in network analysis and synchronization
subspace oriented eigenvalue problems
aggregation/disaggregation or related techniques
hidden Markov models
epidemic models
modelling phylogenetic trees
All papers submitted must meet the publication standards of Linear Algebra
and its Applications and will be refereed in the usual way. They should be
submitted to one of the special editors of this issue listed below by 30
November 2003.
