Subject: Symmetric Matrices

This is in response to Frank Uhlig's request for applications of
symmetric matrices. Cauchy initiated the study of symmetric
eigenvalue problems in connection with the secular motions of the
planets, which (I understand) are long term drifts in their orbits.
In a remarkable paper (reference below), he proved the orthogonality
of the eigenvectors and his famous interlacing theorem. I doubt the
application itself is suitable for the classroom, but it is a nice bit
of history to enliven a course.

Special Issue of the
Journal of Computational and Applied Mathematics


Guest Editor: Volker H. Schulz,
ICA3, University of Stuttgart, Germany

Deadline for Submission of Full Papers: November 30, 1998
Expected Publication: Spring 1999

The numerical solution of optimal control problems is at the
core of many industrial engineering projects. Typically these
problems evolve from simulation tasks defining some output
states to be influenced by some input controls. During the
last years a number of numerical methods have been established,
which treat the states and controls together as unknowns of a
discretized finite dimensional constrained optimization problem
and apply SQP-type methods. Despite the resulting large number
of variables this approach has proven very successful.

The aim of this special issue is to highlight certain aspects of
this approach in the context of ordinary as well as of partial
differential equations (i.e. optimal control in ODE/DAE/PDE).
This special issue will contain papers presenting new research
results in topics including, but not limited to:

* Direct discretization methods
* Fast solution methods for discretized optimal control problems
* Solution error approximation and control
* Shape optimization
* Inverse modeling / parameter estimation
* Optimum experimental design
* Off-line control
* Feedback control
* Nonlinear model predictive control
* Applications in industry and/or science & engineering

All papers will be refereed. All people working in research fields
as listed above are encouraged to submit a contribution according
to the theme of this special issue.

Up to now there are more than 10 tentative submissions from various
fields. This would make already one issue complete. However
Elsevier is willing to publish an even larger number of eligible
papers for this issue.

Subject: Package for Solving Systems of Linear Equations

LINPAR: program package for solving systems of linear equations (SLEs)
including rectangular, singular and ill-conditioned ones

LINPAR implements some methods of Krylov sequence type: two methods of
Abramov's class (ABR and ABR1ORT, see[1]) for densed SLEs and CG, BiCG,
GMRES(m) methods for sparsed SLEs (see [2], [3], [4]).

The full installation of package contains two components: solver kernel and
user's integrated shell.

Kernel was developed in Watcom C 10.6 and works under MS DOS and Windows,
it can be easily recompilated for any other platform without any changes.
This kernel can be used via external calls for solving SLEs that were
generated by user's application and saved to hard disk.

Integrated shell was developed in Borland Delphi and works under Windows
only; it's intended for manual control of solving process and also has some
tools for visual representation of sparsed matrices.

User's systems can be stored in variety of formats including various
orientations and index styles. All these formats are described in online
documentation, some examples are included in distribution set.

Free version of LINPAR has limitations for SLE size: densed system can't be
larger than 2000 and sparsed system can't be larger than 10000; if SLE is
rectangular then bigger dimension is limited. Free version also doesn't
include an incomplete LU preconditioning, only $D^{-1/2}AD^{-1/2}$ is
available to its user. Such version can be downloaded from

(only Russian version of web page and user's guide is available for now).

The further development of LINPAR includes solving of algebraic eigenvalue
problem and parallelization.

Subject: Symposium on Discontinuous Galerkin Methods

Theory, Computation and Applications
Salva Regina College
Newport, RI
May 24-26, 1999


Discontinues Galerkin Methods (DGM) have been developed only recently
but have found use quickly in such diverse applications as aeroacoustics,
semi-conductor device simulation, turbomachinery, turbulent flows,
materials processing, MHD and plasma simulations, and image processing.
While there has been a lot of interest in DGM, only scattered information
is available and there has been no prior effort in organizing a conference
and in publishing the existing volume of knowledge on this subject. We
invite participation of mathematicians, physicists, and engineers working
in this area for possible contributions and plan to publish proceedings
with selective contribution to serve as a reference on the subject.

Subject: Postdoctoral Position at University of Cambridge

University of Cambridge
Department of Applied Mathematics and Theoretical Physics
"Geometric integration of partial differential equations"
Postdoctoral Research Associate

This three-year position commences from 1 January 1999 or as soon as
possible thereafter, in the Numerical Analysis Group (see, as part of the EPSRC-funded
project "Geometric integration of partial differential equations".
Applicants should have (or expect to have submitted) a Ph.D.,
preferably in the field of computational differential equations.

The EPSRC project brings together groups from University of Bath
(Chris Budd), University of Cambridge (Arieh Iserles), Kent University
(Elizabeth Mansfield) and the Meteorological Office (Mike Cullen and
Ian Roulstone). It is concerned with
a. developing and analysing numerical and symbolic algorithms for
partial differential equations of evolution that retain invariants
and symmetries under discretization;
b. applying such algorithms to problems of weather forecasting.
An ideal candidate would have experience in numerical methods and
scientific programming. The project requires a broad expertise in a
range of diverse mathematical techniques, from Lie groups to symbolic
computation to fluid dynamics, but candidates need not be experts in
all of these fields. Instead, an ability to learn, an enquiring mind
and readiness to combine pure, applied and computational modes of
mathematical thinking are expected.

The successful candidate will be based in Cambridge but will keep in
contact (inclusive of short-duration visits) with all the participants
in the project.

Salary is age-related, on the scale GBP 15,740--GBP 21,822.
Further details are available from Arieh Iserles, DAMTP, Silver
Street, Cambridge CB3 9EW, England (email,
to whom applicants should send a full c.v. with the names of three
referees so as to reach him by 15 November 1998. Informal enquiries
are welcome.

University of Cambridge follows an Equal Opportunities Policy.
