Subject: Michael Friedlander Named Wilkinson Fellow at Argonne

Michael Friedlander of Stanford University has been named the 2002
Wilkinson Fellow in Scientific Computing. He will join the
Mathematics and Computer Science (MCS) Division at Argonne National
Laboratory in September.

Friedlander was cited by the selection committee for his understanding
of both mathematical theory and software design. For his thesis, he
devised a novel approach that stabilizes traditional linearly
constrained Lagrangian methods (such as MINOS) for solving large-scale
optimization problems with nonlinear constraints. Such an approach
had eluded researchers for nearly thirty years, and his solution has
generated considerable attention.

Friedlander's background in operations research, engineering
economics, physics, and computer science is unusual. Recently,
Friedlander applied this expertise to help develop efficient methods
for denoising gamma-ray spectrometry data, to address supply chain
optimization problems, and to investigate maximum entropy
classification in speech.

The Wilkinson Fellowship was created by Argonne's Mathematics and
Computer Science Division in memory of Dr. James Hardy Wilkinson,
F.R.S., who for many years acted as a consultant and guiding spirit
for such efforts as the EISPACK and LINPACK projects. The fellowship
is intended to assist a young scientist engaged in state-of-the-art
research in scientific computing.

Subject: Examples of Matrix Contour Integrals

Dear NA-Digest friends:

We all know that in theory, matrix functions like exp(A) can be evaluated
by contour integrals in the complex plane. Sometimes this idea has
proved useful in practice too -- e.g. via the super-accurate trapezoid
rule for smoothly spaced points on a closed contour.

I know a few examples, but they are scattered, and I am sure there is much
more out there. If you know a reference to an application of matrix
contour integrals in numerical computation, would you let me know?
If interesting things turn up I will be happy to report back.

Nick Trefethen, Oxford University

Subject: EigTool for MATLAB released

Version 2.0 of EigTool is now available to download.

EigTool combines the Pseudospectra GUI with MATLAB's eigs command to
provide visualisation of the Arnoldi iteration during an eigs
computation. It includes all of the existing features of the
Pseudospectra GUI along with several new ones, notably norms of matrix
powers and exponentials and a collection of over 30 demos.

EigTool can be downloaded from:

Subject: Workshop in France on Categorical Programming Languages

Second Workshop on Categorical Programming Languages
with an Emphasis on Aldor
9h00-18h00 Thursday July 11, 2002
Maison d'Activit'es Culturelles et de Colloques (MACC)
University of Lille I, Lille, France.

This workshop is a satellite event to ISSAC 2002, the 2002 International
Symposium on Symbolic and Algebraic Computation. ISSAC is the annual
flagship conference in the area of symbolic mathematical computation.

The workshop shall focus on the theoretical and practical issues in the
implementation and use of categorical programming languages, with an
emphasis on the Aldor programming language, its compiler, and libraries.

Particular attention shall be directed to the release of Aldor included
as part of the ISSAC 2002 CD, and to priorities for the next release.

The scientific program shall include presentations by

Manuel Bronstein -- LibAldor: the foundational library
Marc Moreno Maza -- LibAlgebra: the mathematical library
Stephen Watt -- Aldor: the language and compiler

as well as contributed presentations.

Workshop participants shall fall into four groups:

* those who have been central in the establishing the ideas in
categorical programming languages for computer algebra,

* those who have used categorical programming languages in
industrial and other non-university settings

* university researchers and students who might wish to use Aldor
in courses or research projects.

* researchers and students who might wish to contribute to Aldor

Please see for more details
about the workshop and for matters
relating to location, accomodation and transportation.

Subject: Lectureship Position at the University of Leicester

5-year Lectureship in Applied Mathematics at the University of Leicester

Applications are invited for a five-year Lectureship in Applied Mathematics.
Preference will be given to candidates with research interests in applied
partial differential equations, numerical solution of partial differential
equations, and numerical linear algebra, but strong candidates in other
areas of applied mathematics meshing well with the interests of the group's
existing faculty will also be considered. The closing date for applications
is 1 August 2002 and the post is tenable from 1 October 2002. The initial
appointment is on the Lecturer A salary scale, =A320,470 to =A324,435 pa
(March 2002 rates).

The successful candidate will join a lively research group including
research areas of nonlinear dynamics, hp-adaptive finite element methods,
geometric integration, radial basis approximation, stochastic differential
equations, and molecular dynamics. The group received a 5 rating in the
2001 Research Assessment Exercise. Groups in Applied Mathematics, Pure
Mathematics and Computer Science together constitute one of the few
integrated departments of Mathematics and Computer Science in the UK.

Expansion of the group is certain, with priority on applied partial
differential equations and meso-scale modelling. Applied Mathematics Group
members are involved with the multidisciplinary Centre for Mathematical
Modelling (MMC) which houses advanced computing facilities and unites active
researchers in science, engineering, and mathematics with shared interests
in advanced modelling and simulation methods. The MMC organizes a
broad-based research seminar series, funds visiting scholars and small
workshops on Centre-related themes, and hosts an annual distinguished
lectureship. A new building is currently under construction to house members
of the Centre for Mathematical Modelling, including the staff of Applied
Mathematics, as well as some faculty from Computer Science, Engineering and
