**Subject: Looking for Problems Involving Elliptic Operators**

Hello colleagues,

We plan to test the convergence of a new method developed for solving large

dense matrix problems resulting from the spectral solution of differential

equations. We should be very grateful to everyone for sending the clear

descriptions or references of articles concerning the numerical solution of

real world problems represented by selfadjoint elliptic operators the solution

of which requires to solve systems of linear equations or matrix eigenproblems

(not more than 10-20 smallest eigenvalues) with DENSE positive definite

matrices of the order higher than 100 000. Many thanks in advance.

With best regards,

**Subject: Looking for Toeplitz Systems**

Dear NA-NETters,

I am desperately trying to find an example of a *large* linear system with

a positive definite Toeplitz matrix. There are some additional constraints

that seem to make this a difficult problem:

1) The system should be large enough to justify the use of iterative solvers.

2) The system should be moderately ill-conditioned so that one would like to

use a (circulant) preconditioner.

3) The matrix should be Toeplitz in the usual sense, i.e. I am not looking

for block-Toeplitz matrices!

4) The system should arise from a *real application* which can be explained

in reasonable time to math students without sophisticated background

in engineering sciences.

5) If possible, I would like to get real data to play around with, and some

references for background information.

Any help will be greatly appreciated; thanks in advance,

Martin Hanke

**Subject: Zoltan Dynamic Load-Balancing Library**

The Zoltan Dynamic Load-Balancing Library can now be downloaded from the

following URL:

http://www.cs.sandia.gov/Zoltan

The Zoltan library includes a suite of parallel algorithms for dynamically

partitioning problems over sets of processors. Such capability is critical to

applications where work loads and/or geometric locality change as computations

proceed. Examples of such applications include

+ adaptive finite element methods,

+ particle methods,

+ contact detection in crash simulations,

+ multiphysics simulations, and

+ adaptive physics models.

In addition, Zoltan can be used as a parallel static partitioner for

non-dynamic applications, such as traditional finite element methods.

Zoltan is designed to be both flexible and extensible. Its easy-to-use

interface makes it ideal for application developers who would like to experiment

with a variety of load-balancing algorithms. The interface also allows

partitioning-algorithm developers to easily incorporate their algorithms into

Zoltan and compare them with other existing algorithms.

Zoltan provides interfaces for both C and Fortran90. With all communication

done through the MPI library, it is portable to many different architectures.

Zoltan is released under the terms of the GNU Lesser General Public License.

**Subject: New Book, Geometric Partial Differential Equations and Image Analysis**

I'm pleased to announce the publication of a new book of interest to NA-NET:

Geometric Partial Differential

Equations and Image Analysis

by

Guillermo Sapiro

published by Cambridge University Press

This book provides an introduction to the use of geometric partial

differential equations in image processing and computer vision. This

research area brings a number of new concepts into the field,

providing a very fundamental and formal approach to image processing.

State-of-the-art practical results in a large number of real problems

are achieved with the techniques described in this book. Applications

covered include image segmentation, shape analysis, image

enhancement, and tracking. This book will be a useful resource for

researchers and practitioners. It is intended to provide information

for people investigating new solutions to image processing problems

as well as for people searching for existent advanced solutions, and

should appeal to the applied mathematics, computational mathematics,

engineering, and computer science communities.

Contents:

1. Basic mathematical background;

2. Geometric curve and surface evolution;

3. Geodesic curves and minimal surfaces;

4. Geometric diffusion of scalar images;

5. Geometric diffusion of vector valued images;

6. Diffusion on non-flat manifolds;

7. Contrast enhancement;

8. Additional theories and applications.

NUMERICAL ANALYSIS, LINEAR ALGEGRA AND COMPUTATIONS (NALAC)

A Celebration of the 90th Birthday of John Todd

California Institute of Technology

Pasadena, California

May 16-18, 2001

We are pleased to announce that a conference will be held at the

California Institute of Technology, May 16-18, 2001, to honor John

Todd, Emeritus Professor of Mathematics, on the occasion of his 90th

birthday, May 16, 2001. John Todd is one of the pioneers in numerical

analysis, and his scientific contributions extend to analysis, linear

algebra and computation. He has inspired many students at the

California Institute of Technology, as well as colleagues and friends

around the world, and we hope that many will attend this 90th

milestone in his life.

As the title of this conference suggests, we plan to have include

discussions on the past, present, and future of numerical analysis,

linear algebra, and computation. We also plan to have John Todd give

his views on these topics, collected over 50 years of service to

these areas.

In 1949, John Todd became Chief of the Computation Laboratory, which

operated the National Bureau of Standards' Standards Eastern

Automatic Computer (SEAC). Dedicated in 1950, SEAC was one of the

first operational digital computers in the United States. He then

served as Chief of the Numerical Analysis Section of the National

Bureau of Standards from 1954 to 1957 before becoming Professor of

Mathematics at the California Institute of Technology.

Caltech graduates should note that many class reunions will be held

May 17 and 18 (see http://www.its.caltech.edu/%7Ealumni/reunions.htm)

and the annual Seminar Day will be May 19 (see

http://www.its.caltech.edu/~alumni/programs/seminarday.htm).

Mathematical Modelling (IMM) at the Technical University of Denmark,

located in Lyngby 10 km north of Copenhagen.

The summer school is intended for graduate and PhD students interested in the

numerical solution of large-scale problems in science and technology. Students

must be familiar with linear algebra, including Gaussian elimination, LU-

factoration and simple iterative methods. The students must also have some

experience with a programming language such as C or Fortran.

The fee for participation in the summer school is 800 DKK which covers course

material, lunch, dinner, coffee/tea during the day and the excursion. We are

not able to cover any travel expenses. Lodging will take place in a student
