**Subject: Margaret Wright to Receive Honorary Doctorage from Waterloo**

Margaret Wright will receive an honorary doctorate (D.Math) from the

University of Waterloo at its spring convocation this June 14, 2003.

Margaret received her PhD in Computer Science from Stanford University

in 1976, and remained there in its famed Department of Operations

Research until 1988. Subsequently she spent 14 years with the Computing

Sciences Research Center at Bell Laboratories, rising to Head of the

Scientific Computing Research Department in 1997. Currently, she is

Chair of the Computer Science Department at New York University.

Margaret is widely known and respected internationally for her many

contributions to the field of continuous optimization. She, together

with colleagues Phillip Gill, Walter Murray, and Michael Saunders, has

led a revolution in the development of stable algorithms and software

for solving a wide variety of problems in numerical optimization.

Margaret has also been active in service to the mathematical community.

She served as President of the Society for Industrial and Applied

Mathematics (SIAM) in 1995-6, and serves or has served on numerous

senior federal government advisory committees and editorial boards. She

was elected to the National Academy of Engineering in 1997, and was

chosen Emmy Noether Lecturer by the Association of Women in Mathematics

in 2000. She was selected as the Forsythe Lecturer by the Stanford

Computer Science Department in 2000 as well. In 2001 she received the

American Mathematical Society Award for Distinguished Public Service.

Congratulations to Margaret from her many friends and colleagues in the

**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

**Subject: New Book, Meromorphic Functions and Linear Algebra**

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.
