1) Obituary for Guenter Meinardus
From: Hans-Peter Blatt hans....@ku-eichstaett.de and Hans Strauss
str...@am.uni-erlangen.de
Guenter Meinardus died on June 11, 2007 in Neustadt/ Weinstrasse
after having suffered from a severe disease for a long time.
Guenter Meinardus was born on June 11, 1926 in Bremen, Germany. He
went to study Mathematics and Physics at the Universities of Goettingen
and Heidelberg. Under the supervision of C. L. Siegel he received his
doctoral degree from the University of Goettingen in 1953. His dissertation
was concerned with algebraic number theory.
Strongly influenced by Lothar Collatz his interests concentrated on
approximation theory and related topics. After his Habilitation at
the University of Hamburg in 1959 he was offered a Chair of Mathematics
at the Technical University of Clausthal-Zellerfeld in 1964.
In 1968, Guenter Meinardus joined the University of
Erlangen-Nuernberg and
in 1974 the University of Siegen. In 1980 he went to the University
of Mannheim where he taught until his retirement, in 1991.
The principal mathematical interests of Günter Meinardus were in the
subject of Approximation Theory. He wrote the classical monograph
"Approximation of Functions: Theory and Applications".
Guenter Meinardus has had considerable influence on the theory of
nonlinear approximation of functions. Within this area his main interest was
directed towards asymptotic results on rational approximation, especially on
the asymptotic behaviour of the minimal deviations to the exponential
function.
This leads to the famous "1/9"- problem, finally solved with
potential theoretical methods. He stimulated the application of rational
approximations on unbounded intervals for the heat equation. This
fundamental view
was the starting point for investigations of approximations on unbounded
domains where segment approximations also play an important role.
His constructive contribution to nonlinear approximations culminated
in the introduction of asymptotically convex systems which has lead to
generalizations of the local and global Kolmogoroff-criterions and
also to alternation characterizations in the spirit of Chebyshev.
Guenter Meinardus also published many significant papers dealing with
various aspects of spline functions. He developed complex integral
representations of B-splines and gave estimates for the Chebyshev
norm of these splines. Several papers were concerned with bounds of the
norms
of spline interpolation operators. Fundamental results were obtained for
different classes of spline functions. He also considered piecewise
polynomial approximation for functions in one and in two variables and
developed
algorithms for the computation of the best approximations.
Guenter Meinardus organized many international conferences on
Approximation Theory and was asked to join the founding editorial board
of the
Journal of Approximation Theory in 1968, remaining an editor until 1991.
He was
elected member of the Oberwolfach committee and of the German Academy
Leopoldina.
He was guest professor at many universities and had contact to
several prominent colleagues. The Approximation Theory community has lost an
eminent representative.
Guenter Meinardus will be badly missed by all his colleagues and
friends.

3) MTNMS 2008
Dear Colleagues,
This is the first announcement of the 18th International Symposium on the
Mathematical Theory of Networks and Systems (MTNMS 2008), Virginia Tech,
Blacksburg, Virginia, Monday July 28 to Friday August 1, 2007
(arrival date Sunday July 27).
MTNS is one of the main conferences in the general area of mathematical
systems and control theory. The symposium is interdisciplinary and is aimed
at mathematicians, engineers and researchers interested in any aspect of
systems theory. MTNS is usually organized every two years and traditionally
covers areas involving a wide range of research directions in mathematical
systems, networks and control theory.
The list of plenary speakers: Alessandro Astolfi, Martin Golubitsky,
Naomi Leonard, Danny Sorensen and John Tyson. Confirmed semiplenary
speakers include: Mark Embree, Birgit Jacob, Margreta Kuijper, Daniel
Liberzon
,
Iven Mareels, Gyorgy Michaletzky, Bernd Noack, Yoshito Ohta, Alban
Quadrat, Toshiharu Sugie, Harry Trentelman and Victor Vinnikov.
We invite proposals for minicourses, special sessions and contributed
papers. In addition to the book of abstracts, there will be a CD-ROM
distributed at the conference containing longer conference papers.
The deadline for submission of extended abstract/conference paper is
February 15 with notification of Acceptance/Rejection by March 31 and
deadline for final version of the CD-ROM paper of May 15th, 2008.
A second announcement will give details on the date at which the
submission site will be opened. Informal suggestions for minicourses and
special sessions are encouraged at any time; these can be sent to the
conference e-mail address mtns...@math.vt.edu. For additional and
continuing information, consult our conference web site at
http://www.cpe.vt.edu/mtns08/.
Please feel free to pass this information to persons who might be
interested in attending MTNS 2008.
If you do not wish to receive further information about MTNS 2008, please
let us know by sending a message to mtns...@math.vt.edu.
