Subject: Club Modulef

Can anyone furnish information about "Club Modulef."  This is a
group of French (and possibly other) universities and industries.
The common goal is producing and distributing a collection of FEM
codes for fluid flow, elasticity, etc.

I am most interested in any English language references.  Those
I have seen cited are all in French.  If anyone has the code(s) or
has used them, comments would be appreciated.

Subject: Karmarkar's Algorithm

Is there a public domain version of Karmarkar's Algorithm for
linear programming available (i.e. ready to run code?)  Is there
a version that can be bought.  I've heard many researchers are experimenting
with it; has it advanced to the stage of being reliable and robust
software?

LINEAR ALGEBRA AND ITS APPLICATIONS - SPECIAL ISSUE

LINEAR SYSTEMS AND CONTROL

In view of the success of the 1983 special issue on  Linear
Systems  and  Control we think the time is ripe for another issue
which will also focus on those  areas  of  Systems  and  Control
Theory,  Signal Processing and Numerical Algebra where methods of
Linear Algebra are relevant. Note that we use Linear  Algebra  in
the wide sense, thus topics which are linear algebraic in flavour
but  where  analytic  techniques  are  used,  such  as  much   of
H-infinity  theory,  are  not only acceptable but are solicited.
Contributions are invited. Papers should  meet  the  publications
standards  of  Linear Algebra and Its Applications, and they will
be refereed in the usual way.  This  announcement  will  be  made
public  at  some professional meetings, on the E-LETTER
on Systems, Control and Signal Processing  published  by  B.  W.
Dickinson  and  E.  D.  Sontag and the NA-Net distributed from
Stanford.  This is done to meet the planned
publication date.  We are hoping to receive both papers
describing  significant  new  results and well written survey papers
on a relevant topic within the outlines of the special issue.

Appropriate areas include:

Polynomial matrices, rational functions.
Realization theory in its various forms (deterministic, partial,
stochastic).
Inverse scattering.
Large scale or structured systems.
Geometric methods.
Control design methods.
Model reduction.
Stability and quadratic forms, Bezoutians.
Hankel and Toeplitz operators and related operators.
Recursive methods. Interpolation problems.
Fast algorithms, Parallel algorithms.
Factorization theory (coprime, inner outer, Wiener-Hopf).
Parametrization problems in system theory.
Structured eigenvalue problems.
Decentralized control.
The deadline for submission of papers is May 31, 1988, and the
special  issue  is scheduled to appear in spring of 1989.
Papers should be sent to any of the special editors of the issue:

Professor P. A. Fuhrmann Department of Mathematics Ben Gurion  University
of the Negev Beer Sheva, Israel

Professor H. Kimura  Department  of  Mechanical  Engineering  for
Computer-Controlled   Machinery   Faculty  of  Engineering  Osaka
University 2-1, Yamada-oka, Suita Osaka 565, JAPAN

Groningen P.O.Box 800 Groningen, The Netherlands

To: [email-masked]

The Mathematics Department at North Carolina State University has a junior
level tenure track opening in partial differential equations. We are especially
interested in people with research experience in numerical solution of
hyperbolic equations. We are also interested in people working in theoretical
aspects of elliptic equations. Additionally, an applied mathematician using any
aspect of partial differential equations would be of interest to us.

Candidates should send a resume and arrange for three letters of reference
to be sent to

        Michael Shearer
        Department of Mathematics, Box 8205
        North Carolina State University
        Raleigh, NC 27695-8205

Questions can be addressed to [email-masked]. Applications that
are complete by January 15, 1988 are assured of full consideration.

North Carolina State University is also making a special effort to solicit
applications from women and members of minority group faculty in all fields.

Subject: Conference on Iterative Methods

First Announcement

CONFERENCE ON ITERATIVE METHODS FOR LARGE LINEAR SYSTEMS
October 19-21, 1988
The University of Texas at Austin

Celebrating the 65-th Birthday of David M. Young, Jr.

OBJECTIVE
This conference will be dedicated to providing an overview of the state of 
the art in the use of iterative methods for solving sparse linear systems 
with an eye to contributions of the past, present, and future.  The emphasis 
will be placed upon identifying current and future research directions 
in the mainstream of modern scientific computing.

Recently, the use of iterative methods for solving linear systems has 
experienced a resurgence of activity as scientists attach extremely 
complicated three dimensional problems using vector and parallel 
supercomputers.  Many research advances in the development of iterative 
methods for high-speed computers over the past forty years will be reviewed 
as well as focusing on current research.
