Subject: Approximation Theory Network
We are very pleased to announce the formation of AT-NET (Approximation
Theory Network). AT-NET is intended as a ready means for distributing
information to the Approximation Theory community. The more people know
about it and sign on, the better for the community.
It was started by Allan Pinkus and Carl de Boor, and is looking for
volunteers to help run it.
If you have something of general interest to the Approximation Theory
community, such as
o announcement of a meeting
o a question about a technical point
o a reference you cannot find
o the table of contents of the most recent issue of
the AT journal you run
o a short description of the great AT book you have just written
o announcement of a new result or of availability of reports
o and the like
send it to firstname.lastname@example.org (or email@example.com)
for possible distribution to the net.
To sign on to AT-NET, do one of the following from the e-mail address
you wish to have all messages sent from:
a) If you have the "tell" option, simply type:
TELL LISTSERV@TECHNION.TECHNION.AC.IL SUB AT-NET <given_name> <surname>
b) For those without the "tell" option, send an e-mail message to:
with the body of the message consisting of the one line:
SUB AT-NET <given_name> <surname>
Your subscription should be automatically accepted. You will receive
notice of this fact, along with additional information. If you have
problems, write to Allan Pinkus at firstname.lastname@example.org
or Carl de Boor at email@example.com
AT-NET is not an "interactive" list. That is, users cannot post messages
directly to all other users. Messages for distribution should be sent
Please help spread the word, and pass this message on to others who
you think might be interested.

Subject: Delay Differential Equations
I am very much interested in stiff initial value problems for delay
differential equations which arise in practise.
In recent years many numerical methods for solving stiff initial value
problems for delay differential equations have been developed. It is
not clear to me, however, to what extend these problems actually arise
in practise. Therefore, I would appreciate any suggestion. All those
who respond will receive a summary of all contributions.

Subject: Software Available for Boundary Value Problems
The actual versions of our program packages RWPM and RWPKV can be obtained
on 3 discettes from
Martin Hermann (firstname.lastname@example.org)
Friedrich Schiller University Jena
D - (O)6900 JENA
for a nominal handling charge.
Both packages are implemented in MS-Fortran 5.0 and can be run on a PC.
The computation process is graphically depicted.
RWPM: Shooting code for nonlinear two-point boundary value problems;
boundary conditions r(y(a),y(b))=0: multiple shooting
boundary conditions rp(y(a))=0, rq(y(a),y(b))=0, p+q=n: nonlinear
stabilized march method
RWPKV: Path-following, automatic detection and computation of simple
singular points. The code is based on RWPM.

Subject: Preprints/Software Available via Anonymous FTP.
Some technical preprints and research software from Stephen Boyd's
research group at the Electrical Engineering Department at Stanford
University are now available via anonymous ftp to isl.stanford.edu.
The files are organized more or less along the lines suggested by Pete
Stewart in a recent NANET message.
/pub/boyd contains, among other things:
book: Errata for "Linear Controller Design: Limits of Performance",
by Boyd and Barratt.
msd: Matlab and C source for minimum stability degree of parameter
dependent linear systems via a branch and bound algorithm
(described in a paper in the reports directory). Also C
source for a generic branch and bound algorithm.
qdes: Sun 3 & 4 binaries for qdes (a simple proof-of-concept code
for controller design convex optimization using the Q (ie
Youla) parametrization), supporting Matlab scripts, lots of
documentation, and many examples (including the qdes source
for all examples that have appeared in publications).
reports:Postscript preprints on topics such as: global optimization in
control system design & analysis; closed-loop convex
formulation of singular value loop shaping; optimization and
control of rapid thermal processing systems; 1992 ACC
preprints dealing with systems with structured perturbations;
computing the worst-case peak gain of a system with structured

Subject: Mathematical Circus at Ecole Nationale Superieure de Lyon, France.
Location: Ecole Normale Superieure de Lyon, France
Dates: April 3-4 1992
" SOME MATHEMATICAL ASPECTS OF COMBUSTION THEORY"
The "RENCONTRES MATHEMATIQUES", Mathematical Circus, is an informal
meeting of mathematicians to gather around a principal speaker and a
leading subject. It always takes place at ENSL, about every month. The
previous ones were about homogeneisation theory, bifurcation theory,
kinetics equations ...
This time the leading speaker is H. BERESTYCKI, University of Paris VI.
He will give three talks covering various aspects of flame theory, free
boundary problem, qualitative aspects of elliptic equations and stability.
He will be surrounded by:
C-M BRAUNER: University of Bordeaux, France
G. JOULIN: ENSMA Poitiers, France
W. DOLD: University of Bristol, England
The circus is unique in that it is VERY informal, and thus allows
us to talk about the very latest results as well as interesting work
in progress. In our previous meetings there has been lots of informal
discussion and a very healthy mix of industrial and academic participants.
GRADUATE STUDENTS ARE WELCOME !
We have arranged special conference train fares with SNCF. Ask just
for a "Congress Ticket".
A restricted number of uncharged rooms are at our disposal on Campus.
There is also some hotels a few minutes' ride from ENSL campus.
To register, please send e-mail to Claudine Schmidt-Laine at the
adress below. As usual, there is no registration fee.
The circus will begin on Friday morning and will end on Saturday noon.
