Subject: Test Polynomials

Dear Colleagues,

I would be very grateful to hear of any references to papers
or software repositories pointing to a collection of test polynomials.

I have one reference ( Henrici and Watkins (1965), Comm. ACM, pp. 570 - 574 )
which lists a collection of test polynomials. The collection is NOT
exhaustive ( I Think! ) and would like to know of any recent entries.

Thank you in anticipation.

Subject: RKSUITE

Dear colleagues,

RKSUITE, f77 software for initial value problems in ODEs, has been made
available on netlib for over two years. Recently, a corresponding full f90
implementation of the software has also been made available on netlib
(in the ode/rksuite directory). We would be grateful to receive any and
all comments on either the f77 or f90 versions of RKSUITE.

As the authors, we are considering what enhancements we might include
in a second release of the f77 version of RKSUITE and have recently
conducted an electronic survey of users who have downloaded RKSUITE. If
you haven't received the survey or have not answered the survey we would
be grateful to receive any input you may have.

Enhancements currently under consideration include
- an interpolant for the 7(8) pair
- treatment of complex dependent variables (already available in the
f90 version)
- inclusion of a "g-stop" facility (event location)
- more examples

Please forward your responses to >>> <<<

Subject: Perturbation Bounds for the Hessenberg factorization

I would like to know where, in the literature, I could
find perturbation bounds for the Hessenberg
factorization of a matrix A = Q H Q^* (i.e., given a
perturbation $\Delta A$ on A, bounds for the resulting
perturbation on Q and H).
G. W. Stewart (1993) established already similar bounds for
the LU, the Cholesky and the QR factorizations, but so far
I read nothing about the Hessenberg factorization.
Any clue is welcome! Many thanks for your help,

Valerie Fraysse.

high-performance computing resources. PVM introduces distributed
computing, discusses where and how to get the PVM software, provides an
overview of PVM and a tutorial on setting up and running existing
programs, and introduces basic programming techniques (e.g. putting PVM
in existing code. There are program examples and details on how PVM
works on UNIX and multiprocessor systems, advanced topics (portability,
debugging, improving performance) and troubleshooting.

PVM (Parallel Virtual Machine) is a software package that enables the
computer user to define and allow a networked heterogeneous collection of
serial, parallel, and vector computers to function as one large computer.
It can be used as stand-alone software or as a foundation for other
heterogeneous network software. PVM may be configured to contain various
machine architectures, including sequential processors, vector
processors, and multicomputers, and it can be ported to new computer
architectures that may emerge.

conference will bring together these diverse groups for an exchange
of their latest ideas.

Topics included:
o Solutions of ordinary and partial differential equations,
including symmetry methods.
o The use of symbolic techniques for numerical computations.
o Applications of Grobner basis algorithms.
o The use of quantifier elimination algorithms to solve problems
in engineering.
o The use of computer algebra in education, including precollege,
college, and graduate education.
o Application of computer algebra to problems in engineering
and science.

The conference will be run in the standard IMACS format where
individuals are invited to organize a special session. Requests
for proposals for special session will also be issued.

Subject: Position Available at Brunel University


Up to one year, Non-UK EU Citizen

A Research Fellowship is immediately available for up to one year in BICOM
for research into the finite element modelling of thermoforming processes
for the creation of container structures from thin polymeric sheets. The
work entails the extension of an existing finite element model for the
thermoforming of axisymmetric structures to nonaxisymmetric structures with
more complicated geometries. A dedicated SUN workstation is available for
the project.

The Research Fellow will need to be familiar with finite element modelling
of problems in continuum mechanics. Some knowledge of solid mechanics and
surface approximation, and familiarity with the SUN/UNIX environment would
be an advantage. Excellent programming skills are essential.

The position is financed from an EU Human Capital and Mobility Grant and is
available only to non-UK EU citizens. Interested persons should, as soon as
possible, contact
