**Subject: Numerical Dual Integral Equations**

In modelling the melting effect of lightning on a metal surface,

I had to solve the following typical problem:

A semi-infinite homogeneous solid, at constant temperature T=0,

at time t=0 is suddendly heathed on its free surface, z=0, by

a disk (radius a), at constant temperature T=To, the remaining part of

surface supposed to be thermally insulated (i.e. no heath flux). This

is a mixed-boudary value problem.

The steady state solution, t->infinity, can be found in standard text

(Carlaw-Jaeger, CHS, cap.8, p.215,eq.(9)) and is

T(r,z)=(2To/pg)arcsin(2a/(A+B)),

A=Sqrt[(r-a)^2+z^2]

B=Sqrt{(r+a)^2+z^2].

I have found a time depending solution using Laplce transform and Hankel

transform to eliminate time and radial dependence in heath equation. In

this way the problem, with the prescribed boundary value, is reduced to a

couple of dual integral equations. These equations can be solved

numerically by series of Bessel functions, as done by Sommerfeld (Ann.der

Physik (1942/43) ,42, pag. 395).

The major difficulty are now in the inverse transformations which look

almost prohibitive.

This very elementary problem has a very complex solution.

Anyone knows other simpler methods or references to analogous

situations with dual integral equations?

Any help will be greatly appreciated.

**Subject: Roots of Convex Functions**

Dear NA-netters,

I would like to find the *roots* of a family of convex functions. That is

f_k(x_1,...,x_n) = 0 for k=1..n, where each f_k(x) is convex. Is anyone

aware of an algorithm guaranteed to work (or prove no roots exist) in

this case?

The two forms of f_k(x) I am specifically interested in are

f_k(x) = max_{1 \leq j \leq n_k} (m_{kj} \cdot x + b_{kj})

[ so f_k is the maximum over a finite family of linear functions ]

which is really just an approximation for

f_k(x) = log[ sum_{j=1}^{n_k} \exp (m_{kj} \cdot x + b_{kj}) ]

[ so f_k is the log of the sum of the exponentials of linear functions ]

Hi everyone,

Does anybody have (or knows) a routine for finding

**Subject: Algorithms for Arbitrary Precision Floating Point Arithmetic**

Dear NA-Netters,

For an application of embedded onboard satellite'software, I will wish

to locally increase the floating point precision of the four basic

operations available on my processor ( MIL-STD-1750 with extended floating

point data : 48 bit consisting of a 40-bit 2'complement mantissa and an

8-bit 2'complement exponent).

I seek algorithms which use only one fixed precision (the extended

floating point precision) available on my processor (as the algo. for

arbitrary precision floating arithmetic of Douglas D.Priest- Preprint 1992)

and not algorithms which are based on libraries as MP (A FORTRAN Multiple

Precision arithmetic Package) of Richard P. Brent, ....

If you have some information (preprints, freeware, .... ) for my

problem, please let me know. Any reference would be helpful.

Thanks.

**Subject: New Book, Level Set Methods and Fast Marching Methods**

I am pleased to announce the publication of a new book, entitled

"Level Set Methods and Fast Marching Methods"

J.A. Sethian

published by Cambridge University Press

This book provides an introduction to level set methods and fast marching

methods, which are powerful numerical techniques for analyzing and computing

interface motion in a host of settings. They rely on a fundamental shift in

how one views moving boundaries, rethinking the natural Lagrangian perspective

and exchanging it for an Eulerian, initial value partial differential equation

perspective. The resulting numerical techniques can be used to track three-

dimensional complex fronts that can develop sharp corners and change topology

as they evolve.

This new edition is a superset of the earlier book, "Level Set Methods",

published in 1996, in that it contains everything in the previous edition, as

well as a collection of new topics, including:

(1) Level set and Fast Marching Methods on unstructured meshes,

(2) General and automatic coupling of interface techniques to

complex physics and chemistry, methods.

(3) Methods which provide high order accuracy, conserve mass,

and avoid all re-initialization, including scheme error analysis.

(4) New application areas, including: Sintering and flow under the

second derivative of curvature, shape smoothing and image

processing/segmentation, fast techniques for computing visibility

in complex scenes, semiconductor simulations and comparison with

experiment, construction of shortest geodesic paths,

connections with network path algorithms, electromigration,

fluid mechanics, aircraft avoidance, control theory, and

seismology.

This new edition is available in both hardback and paperback.

Published June 1999, 398 pages

ISBNs 0 521 64204 3 HB

0 521 64557 3 PB

For more information, please see the Cambridge University Press online

catalogs at http://www.cup.org and http://www.cup.cam.ac.uk

The first chapter may be downloaded from the website:

http://math.berkeley.edu/~sethian/level_set.html

An accompanying web site has beed developed devoted to these topics,

which includes

(1) Interactive Java scripts on robotic navigation, medical image

segmentation, image processing, and curve evolution,

(2) A large number of movies about fluids, semiconductors, geometry,

imaging, segmentation, etc.,

(3) The history and evolution of this field, with reference material,

NEW BOOK

INDEFINITE QUADRATIC ESTIMATION AND CONTROL:

A Unified Approach to H_2 and H_oo Theories

B. Hassibi, A. H. Sayed, and T. Kailath

Studies in Applied Mathematics, vol. 16,

SIAM, PA. Hardcover. xvii+555 pages.

ISBN 0-89871-411-7.

Description:

This monograph presents a unified mathematical framework

for a wide range of problems in estimation and control.

The authors discuss two most commonly used methodologies:

the stochastic H_2 approach and the deterministic (worst-

case) H_oo approach. Despite the fundamental differences

in the philosophies of these two approaches, the authors

have discovered that, if indefinite metric spaces are

considered, they can be treated in the same way, and are

essentially the same. The benefits and consequences of

this unification are pursued in detail, with discussions

of how to generalize well-known results from H_2 theory

to the H_oo setting, as well as new results and insights,

the development of new algorithms, and applications to

adaptive signal processing.

Table of Contents:

1. Introduction and Motivation

2. Linear Estimation in Krein Spaces

3. State-Space Models in Krein Space

4. Finite Horizon H_oo Filtering

5. Array Algorithms

6. Several Related Problems

7. H_oo Optimality of the LMS Algorithm

8. Duality

9. Finite-Horizon Control Problems

10. Input-Output Approach to H_2 and H_oo Estimation

11. Input-Output Approach to H_2 and H_oo Control

12. The Discrete-Time Algebraic Riccati Equation

13. Infinite-Horizon Results for State-Space Models

14. Asymptotic Behavior

15. Optimal H_oo Solutions

16. Continuous-Time Results and Final Remarks

Bibliography

Index

Audience:

Written for the second-year graduate student in electrical,

mechanical, or aerospace engineering, the book requires a

basic understanding of linear algebra and linear systems

theory. Researchers in systems and control, signal

processing, communications, and numerical algorithm

development will also find this book useful.

**Subject: Workshop on the Future of Mathematical Communication**

The Future of Mathematical Communication, 1999

Mathematical Sciences Research Institute

Berkeley, California, USA

December 2-5, 1999

This is the first announcement for a workshop on the probable evolution of

mathematical communication in coming years. It is presently sponsored by

- the International Mathematical Union (IMU)

- the Mathematical Sciences Research Institute (MSRI)

- the Centre de Recherches Mathematiques (CRM)

- the Fields Institute (FI)

- the Pacific Institute for the Mathematical Sciences (PIMS)

The workshop will take place almost exactly five years after the 1994

MSRI meeting on "The Future of Mathematical Communication"

(www.msri.org/activities/events/9495/fmc/fmc.html) and is intended to

provide a snapshot at the start of the millennium of the present state of

mathematical communication and a provocative look at the future - from

various perspectives and engaging diverse stake-holder groups. It is

hoped that this will provide a useful precursor to world-wide mathematical

activities in the World Mathematical Year, WMY 2000, as the IMU has

designated the year 2000.

The workshop will be preceded by a half-day training workshop on the

use of streaming video, and followed by a day of working sessions of

the IMU's Committee on Electronic Information and Communication (CEIC).

A limited amount of funding is available for partial support of people

wishing to attend. Students, recent Ph.D.'s, women, and minorities are

particularly encouraged to apply. To apply for funding, send a letter

explaining your interest in the workshop together with a vita or

bibliography, estimated travel and/or living expenses. If you are

a student, also solicit a letter from a faculty advisor. This

information should be sent to one of the co-chairs of the conference.

- Dec 2 (Thursday): Streaming video workshop in the morning, as

well as registration, followed by four afternoon talks, on the

UC Berkeley campus, aimed at a very general audience. There will

be a banquet in the evening.

- Dec 3 (Friday): A day devoted to "publishing" broadly construed and

aiming for four morning talks and four afternoon talks addressing

issues such as: preprint servers, journals, books, subscription

models, intellectual property and copyright.

- Dec 4 (Saturday): A day devoted to "tools" of various sorts and again

aiming at four morning and four afternoon presentations, addressing

issues such as: protocols and languages for scientific communication,

meta-data and search mechanisms, multi-media, interactive tools,

computational packages, real time and asynchronous tools for

collaboration.

- Dec 5 (Sunday): The IMU's Committee on Electronic Information and

Communication} (CEIC) will hold a day of working sessions and

invites participants at the workshop to attend.

The Scientific Committee of the conference is:

- bergeron@lacim.uqam.ca (Francois Bergeron, CRM)

- jborwein@cecm.sfu.ca (Jonathan Borwein, PIMS & CEIC (co-chair))

- jpb@msri.org (Joe Buhler, MSRI (co-chair))

- hartb@mcmaster.ca (Bradd Hart, FI)

- groetschel@zib.de (Martin Groetschel, IMU & CEIC)

- Peter.Michor@esi.ac.at (Peter Michor, EMS & CEIC)

- amo@research.att.com (Andrew Odlyzko)

The precise schedule is still somewhat in flux, and it is possible that

there will be room for contributed papers; if you are interested in

speaking at the conference, please contact one of the co-chairs.

**Subject: Faculty Position at Johannes Kepler University**

Announcement of a Professorship for Scientific Computing

The College of Science and Engineering of the Johannes Kepler University

in Linz (Austria) advertises a newly created professorship (second salary

category) for Scientific Computing to be filled on or after October 1, 2000.

We are looking for a mathematician with habilitation or equivalent

qualification with a relevant publication record preferably in the area of

geometric analysis in connection with nonlinear partial differential

equations or calculus of variations, especially scientific visualization

Candidates should be able to establish and lead an externally-funded

research group; they should have the necessary pedagogical qualification for

teaching at all levels. Applicants whose research profile fits

into the Special Research Project "Numerical and Symbolic

Scientific Computing" will be preferred; this special research

project deals with the interaction between numerics, symbolics and

graphics in connection with partial differential equations from

science and technology. Especially the areas of graphics and of

software technology for mathematical systems should be strengthened

by this appointment.

The Johannes Kepler University specifically encourages female

candidates to apply, with a view to increasing the proportion of

female professors. Women candidates will be given preference over

equally qualified male applicants.

Applications should be accompanied by a curriculum vitae, list of

publications, teaching record, and copies of five of the

candidate's most important and relevant publications and should be

submitted to Dean Prof. Dr.Heinz W. ENGL, Dekanat der TNF,

**Subject: Student Position at Chalmers University of Technology**

PhD student position at Chalmers University of Technology, Gothenburg, Sweden

Department of applied mathematics/optimization

A PhD student position in optimization is offered. The position is

placed at the department of mathematics at Chalmers University of Technology.

The position has its focus within the research project 'Mathematical

models and optimization methods for robust optimal design'.

In the project, design problems in structural mechanics are

considered, wherein the shape, topology and/or material is to be

chosen optimally when parameters in the problem (for example, the

material properties or the external loads acting on the mechanical

structure) are uncertain or vary in a random fashion. What is sought

is a structure that is stable with respect to the random variations of

these parameters, and thus constitutes a form of robust, or,

stochastic, optimization problem of a bilevel (hierarchical) form.

The project is interdisciplinary in that it combines engineering

sciences, in particular structural and solid mechanics, and applied

mathematics, in particular optimization, numerical analysis and

mathematical statistics. The project is performed jointly between the

optimization group at mathematics, and two groups in mechanics at

Chalmers and Linkoping University (Sweden).

The PhD position is limited to 5 years, of which about 20% is devoted

to teaching or other departmental duties. The PhD position comes with

the benefits of a normal job (salary, social security, ...).

Applicants should have an undergraduate degree in an area closely

related to one or more of the project subjects.

The deadline for applications is August 31, 1999.

For more information, please contact associate professor Michael

Patriksson, tel. +46 31 772 3529, e-mail mipat@math.chalmers.se, URL
