Subject: A Problem of Sparse Matrix Numbering

Dear Colleagues,

My research deals with finite element modeling of porous composites. To
mesh a specimen I need to divide it into large number of elements. As a
result the stiffness matrix is a very large and sparse. Unfortunately, the
computer do not solve such matrix right. I have an idea to numbering the
nodes so as the matrix has band type. Could you please inform me about any
program or algorithm which has a possibility to renumber it in such way. I
would like to receive any help from you.
With best regards.

Sincerely,
Pavel Bondarev

BRIEF DESCRIPTION:
Semidefinite programming (SDP) has been one of the most exciting and
active research areas in optimization during the 1990's. It has
attracted researchers with very diverse backgrounds, including experts
in convex programming, linear algebra, numerical optimization,
combinatorial optimization, control theory, and statistics.
This tremendous research activity was spurred by the discovery of
important applications in combinatorial optimization and control theory,
the development of efficient interior-point algorithms for solving
SDP problems, and the depth and elegance of the underlying
optimization theory.

The HANDBOOK OF SEMIDEFINITE PROGRAMMING offers an advanced and
broad overview of the current state of the field, It contains
nineteen chapters written by the leading experts on the subject.
The chapters are organized in three parts: Theory, Algorithms, and
Applications and Extensions.

Subject: Search of Venue for the FoCM 2002 Conference

Search of venue for the FoCM 2002 Conference

Following the very successful second international conference on the
Foundations of Computational Mathematics (FoCM) at Oxford University
in July 1999 which attracted 320 participants and a high-powered cast
of foremost world authorities from all branches of mathematics, the
Executive Committee of FoCM is now investigating possible venues and
calling for proposals for the next FoCM conference in Summer 2002.
Although the Committee is open-minded as to the geographic location,
there is a definite body of opinion to the effect that this is North
America's turn (after Brazil and the UK).

If you contemplate the idea of organising the next FoCM conference,
please drop an e-mail to Endre.Suli@comlab.ox.ac.uk as soon as possible
to explore this further. Formal applications (up to 2 pages long) should
be sent to him by 31 March, 2000, including details about lecture room
facilities, quality and cost of local accommodation and subsistence,
convenience of travel to the region, and potential sources of funding.

The FoCM Executive Committee expects to announce the venue and the
likely time of the next FoCM conference in April 2000.

The aim of FoCM as an organisation is to explore and foster the interactions
and establish a common agenda between computational mathematics, pure
mathematics and computer science through conferences, workshops and series
of publications which include the new Springer-Verlag journal
Foundations of Computational Mathematics'', edited by Mike Shub, and the
new Cambridge University Press monograph series Library of Computational
Mathematics'' published under the FoCM imprint.

Subject: Postdoctoral Position at University of Chicago

We are seeking a colleague to help us develop innovative mathematical
and computational techniques for Adaptive Optics (AO) at the University
of Chicago. Adaptive optics achieves real-time, diffraction-limited
imaging by measuring a distorted wavefront from a "guide" source (e.g.,
a laser) and applying control signals to a deformable mirror which
corrects the wavefront. This technique is revolutionizing astronomy,
allowing an order of magnitude increase in the resolution of ground
based astronomical telescopes, and it has important applications in
vision, as well as other medical and industrial applications.

The University of Chicago is developing a laser-beacon AO facility at
Apache Point, New Mexico, under major NSF support, and it is part of
the new NSF-funded Science and Technology Center for Adaptive Optics
based at Santa Cruz, California (http://www.ucolick.org/~cfao). The
successful applicant will be a member of the Computation Institute
(http://www-fp.mcs.anl.gov/ci) which is planning the construction of
a highly parallel low cost processing system, scalable to Teraflop
speeds, for adaptive optics and related applications.

Candidates should have a recent doctoral degree in mathematics,
computer science, engineering or applied science. They should have
detailed experience with basic numerical analysis (numerical linear
algebra and methods for discretizing partial differential equations)
and mathematical modeling. Support personell will be available to
implement both hardware and software systems, but the ideal candidate
will be able to interact closely with all aspects of the systems being
created, from concept through implementation.

The appointment will be for three years in the first instance with the
possibility of extension of a further two more years. More details of
the work being carried out in this field at Chicago can be found at

Linear Algebra and its Applications

Special Issue on

INFINITE SYSTEMS OF LINEAR EQUATIONS FINITELY SPECIFIED

Second Announcement

One of the traditional hunting grounds of linear algebra is
the area of finite systems of linear equations, as described by a
matrix equation $Ax = b$. Here $A$ is a known matrix,
$b$ a known vector of finite dimensions, and $x$ is an unknown
vector of finite dimensions, which is to be determined such
that the equation is either satisfied, or, if that is not possible,
approximately satisfied. Many techniques are known for finding solutions
or approximate solutions, depending on the properties of the
given data and the approximation technique choosen.

If the system of equations is not finite, i.e. $A$ is not a matrix
but an operator, and $b$ and $x$ are of infinite dimension, then
algebraic and numerical techniques can still be used provided the
given data are finitely specified. Operators with such a property
are often called 'structured operators', and it turns out that
one can solve such infinite equations in an exact or approximate sense using
finite methods and algorithms.

The conjunction of linear algebra and inversion theory for finitely
specified infinite operators brings interesting connections to the
forefront: algebraic equivalents of inner-outer factorizations e.g.,
or the algebraic significance of Kalman filtering. Structured matrices
can be of many types, e.g. systems with finite displacement ranks or
time-varying systems with state spaces of finite dimensions and whose
limiting behaviour is known, e.g. as a time invariant system.

A non-limiting list of topics of interest in this area is (assuming
$A$ is an infinite but finitely described operator of some kind):
- inversion methods
- decomposition methods for the operator A
- complexity reduction
- equivalencies
- canonical forms
- transform techniques.

Examples of operator structure:
- systems with low displacement rank
- finitely described time-varying systems
- finitely described almost-periodic systems
- differentials of non-linear systems.

Interested authors are kindly invited to submit full papers with
significant contributions to this area to any of the three
guest editors listed below before June 1st, 2000.
