**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.

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**

POST DOCTORIAL POSITION IN ADAPTIVE OPTICS AND ADAVANCED COMPUTING

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

- quadratic approximation methods

- 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.
