Subject: Computational and Applied Mathematics at UT-Austin

The Computational and Applied Mathematics (CAM) program is an
interdisciplinary graduate program at the University of Texas at
Austin. This exciting program draws from the strengths of the various
departments and colleges on campus. Associated with CAM is the Texas
Institute for Computational and Applied Mathematics (TICAM).

Graduate study in Computational And Applied Mathematics embraces three
component areas: applicable mathematics, numerical analysis and
scientific computations, and mathematical modeling and applications
chosen from an approved area in engineering or science. Graduate
study opportunities are offered in numerical analysis and scientific
computing, applicable mathematics, computational mechanics and
physics, parallel computing and computer architecture, mathematical
modeling, and in supporting areas in engineering and science which
involve mathematical modeling of physical phenomena and engineering
systems.

TICAM offices and labs cover 10,000 square feet of newly renovated
office space centrally located on campus. Extensive computing
facilities are available for research by faculty members and graduate
students in CAM, including a scientific visualization lab, a network

Subject: Help with Matrix Algebra Proof

Hi,
I am a grad student in the department Electrical and Computer
Engineering at Rice. In the course of my research, I came across
a proposition in matrix algebra that I need to prove and I've spent 3 days
on it with no success. Everyone I've asked in my department seem to
be stumped too. If someone knows the proof or has seen a similar
much.

Problem:
Given: R -- a symmetric positive definite matrix and
P -- a diagonal matrix with entries of form exp(j*phi_m), where
j = sqrt(-1) and all phi_m's aren't equal

To prove:
i) k^th diagonal element of inv(R + P'RP) <= (1/2)*(k^th diagonal element
of inv(R)) ..... where P' denotes Hermitian transpose of P

ii) And in general, to prove that
k^th diagonal element of inv(R + P'RP + (P^2)'R(P^2) + ... +
(P^M)'R(P^M)) <= (1/(M+1))*(k^th diagonal element of inv(R))

IRREGULAR'96

PRELIMINARY ANNOUNCEMENT AND CALL FOR PAPERS
THIRD INTERNATIONAL WORKSHOP ON
PARALLEL ALGORITHMS FOR IRREGULARLY STRUCTURED PROBLEMS

Santa Barbara, August 19--21, 1996

Efficient parallel solutions have been found to many problems. Some of
these solutions can be automatically obtained from sequential programs
using compilers. However, there still exist a large class of problems,
known as irregularly structured problems, that lack efficient solutions.

The workshop on Parallel Algorithms for Irregularly Structured Problems
- IRREGULAR 96 - is the third in the series, after Geneva and Lyon,
that addresses issues related to deriving efficient solutions to
irregularly structured problems. It will be held at the University of
California, Santa Barbara, on August 19--21, 1996.

Scope : IRREGULAR 96 aims at fostering the cooperation among
practitioners and theoreticians of the field. Papers for oral
presentation are solicited in all research areas related to the
parallelism of irregular problems, as listed below.

Topics : (non exhaustive) applications, approximating and randomized methods,
automatic synthesis, branch and bound, combinatorial optimization, compiling,
computer vision, load balancing, parallel data structures, scheduling
and mapping, sparse matrix and symbolic computation.

Publication : Proceedings are planned to be published in the Springer-Verlag
Lecture Notes in Computer Science series and shall be available at the
workshop. The Proccedings of IRREGULAR'95 have been published as volume 980
of Lecture Notes in Computer Science, Springer-Verlarg.

Submission guidelines : To submit a contribution, send 6 copies
of an extended abstract describing original research
in no more than 15 pages to

Computer Science Dept.
University of Minnesota
4-192 EE/CSci Building
200 Union Street S.E.
Minneapolis, MN 55455
USA

Papers simultaneously submitted to other conferences with published
proceedings will not be considered.

Hard copy contributions must be in Minneapolis and
e-mail (post-script file) contributions must be at
irregular_submit@cs.ucsb.edu
no later than March 15, 1996.

A cover page should contain the author's full name, address, a 100-word
abstract and keywords. If the paper is submitted electronically, the
cover page in the form of an ascii-only e-mail must contain the
same information.

Venue : Santa Barbara is situated on the Pacific coast, ninety miles north of
Los Angeles and a one-day trip from the wine country and horse ranches of
neighboring Santa Ynez Valley. Santa Barbara's Spanish heritage is reflected
in its architectural style, fiesta celebrations and historical landmarks, and
its mild climate promotes an environment rich in outdoor activities.

Subject: Conference on Finite Element Methods

An International Conference on

Finite Element Methods: Superconvergence,
Post-processing and A Posteriori Estimates
University of Jyvaskyla, Finland, July 1-4, 1996

FIRST ANNOUNCEMENT

During the development of the finite element method it has been
found that at some exceptional points the rate of convergence of
FE-approximations exceeds the optimal global rate. This phenomenon has
come to be known as superconvergence''. The rate of local or global
convergence con be improved also by various post-processing techniques.

The aim of the conference is to bring together people who work on
superconvergence phenomena and a posteriori estimates in the numerical
solution of differential and integral equation, variational inequa-
lities and other problems of mathematical physics. The organizers
intend to publish the conference proceedings. Thus, all participants
are kindly asked to prepare survey papers of their own results.
Articles with new superconvergence results are welcome as well. The
length of any contribution should not exceed 15 pages in TEX.

Subject: Position at CERFACS

We are looking for someone at post-doc level with experience, interest,
and background (with publications) in both mathematics and computer
science.
The position is open in the framework of an ESPRIT contract in connection
with European reseach centres and industrial partners. For this project
we want someone with experience both in parallel computing and numerical
software techniques.
The heart of the activity concerns the numerical reliability of software.
There exist methods for analysing models and algorithms that give an
indication of the confidence to be placed in the accuracy of simulation
results. The task to be completed at CERFACS consists mainly in developing
a tool which employs these methods, called PRECISE, that will be used in the
project for confidence testing of algorithms and applications. A prototype
tool already exists so the consortium can begin testing internally early in
the project. The prototype version is written for Matlab and one of the aims
of this workpackage is to improve its capabilities.
Some of the work will be in translating PRECISE to Fortran to allow
larger (and more realistic) problems to be handled and in the production of
commercial quality documentation for the tool.

The position is in the Qualitative Computing Group at CERFACS, whose main
research activities are
- study of the stability and the reliability of numerical methods,
specifically in the neighbourhood of singularities,
- design of robust codes for computing some eigenelements of very large
and nonnormal matrices (Arnoldi Tchebycheff method),
- influence of high nonnormality on the reliability of
iterative methods in linear algebra,
- identification of physical applications giving birth to highly
nonnormal matrices, in CFD in particular,
- software tools for assessing the quality (reliability, robustness) of
numerical methods.

This group is part of the Parallel Algorithms Project lead by Iain Duff.
