**Subject: Looking for BEM code**

I am looking for codes implementing the BEM for

a Poisson problem on a smooth or piecewise smooth boundary

with Dirichlet, Neumann or mixed boundary conditions.

Source codes in Fortran or C, available by ftp,

are mostly convenient, but any other pointer

or reference is also appreciated.

Thanks,

**Subject: Krylov Subspace Methods and Applications**

Workshop on Krylov Subspace Methods and Applications

A workshop on Krylov Subspace Methods and Applications will be held

on or near the campus of North Carolina State University in Raleigh,

North Carolina on March 17 and 18, 1995. The organizers are Ilse

Ipsen (ipsen@math.ncsu.edu) and Tim Kelley (Tim_Kelley@ncsu.edu).

The goal of the workshop is

to broaden communication between the theoretical and

applications camps by providing painless, and in fact stimulating

opportunities that help participants from both camps to learn about

each others' problems and results. We want to ensure that numerical

analysts become interested in the constraints of specific applications

problems; and that engineers and scientists learn about the newest

mathematical results in such a way that they can evaluate the

potential of these methods for their own problems. Moreover, we have

to make sure that the problems and results are presented in a language

understood in both camps.

The workshop will consist of four half-day presentations on

the interaction between theoretical, numerical and application

specific aspects of a Krylov space method. Each presentation will

be given by a two-person team consisting of a numerical analyst and

a person working in an application area.

The teams and the topics of their presentations are

Yousef Saad (University of Minnesota),

Michael Heroux (Cray Research):

Fluid Flow Problems on Unstructured Meshes.

Dan Sorensen (Rice University),

Henk van der Vorst (Utrecht University, The Netherlands)

Magnetohydrodynamics

Nick Trefethen (Cornell University),

Peter Schmid (University of Washington):

Hydrodynamic Stability

Linda Petzold (University of Minnesota)

Peter van Keken (University of Michigan)

Computational Geodynamics and Numerical Relativity

To get your name on the mailing list and obtain more complete information

on registration, logistics, and the program, send electronic mail to

or finger krylov@math.ncsu.edu.

We hope to have some support from the National Science Foundation to

support attendance by graduate students and Ph. D.s at the early stages

of their careers. When and if this is finalized, we will make an

announcement to the mailing list.

"Large Scale Optimization, State of the Art"

W.W. Hager, D.W. Hearn, P.M. Pardalos, Editors

Kluwer Academic Publishers (1994), ISBN 0-7923-2798-5.

This book is a collection of papers presented at the Large Scale

Optimization Conference held at the Center for Applied Optimization,

University of Florida, Gainesville, in February 1993.

Accurate modelling of scientific problems often leads to the

formulation of large-scale optimization problems involving thousands

of continuous and/or discrete variables. As a consequence of new

algorithmic developments and of the increased power of computers,

large-scale optimization has seen a dramatic increase in activities

in the past decade.

Topics include large-scale linear, nonlinear and stochastic

programming, network optimization, decomposition methods for optimal

control, nonsmooth equations, integer programming, and software

development. In addition, applications are included in location

theory, structural mechanics, molecular configuration,

transportation, multitarget tracking, and database design.

The book will be a valuable source of information for faculty,

students and researchers in mathematical programming and related

fields.

A NEW JOURNAL PUBLISHED BY WILEY

NUMERICAL LINEAR ALGEBRA WITH APPLICATIONS

Aims and Scope

This journal is directed at researchers in Numerical Analysis,

Computer Sciences and Natural Sciences, engineers and economists

who either take part in the development of methods in Numerical

Linear Algebra or use such methods in their research.

Topics covered include (but are not limited to):

-Conjugate Gradients like and other iterative methods;

-Preconditioning Methods; Direct Solution Methods;

-Numerical Methods for Eigenproblems;

-Newton-like Methods for Nonlinear Equations;

-Parallel and Vectorizable Algorithms in Num. Lin. Algebra;

-Application of Methods of Numerical Linear Algebra in Science,

Engineering and Economics.

The journal emphasizes mathematical rigour in presenting new methods

in Numerical Linear Algebra including their analysis and applications.

Where it turns out to be difficult to give full mathematical rigour

to the presentation, well-chosen numerical test problems can suffice

to demonstrate the usefulness of the presented method, if these are

accompanied by a discussion and heuristic explanations.

The journal also emphasizes analysis of the computational and

communication complexity of algorithms in Numerical Linear Algebra

when implemented on different computer architectures.

The journal solicits original research papers and survey articles. All

papers should contain a discussion indicating in which area(s) the

approach, suggested in the paper, can be used. The authors should

strive at ensuring that the presented methods are easily understandable

by as broad a spectrum of readers as possible.

Initial submission: Four copies of the manuscript should be sent to the

**Subject: Post Doc at Bristol, U.K.**

Postdoctoral research assistant in

Applied Nonlinear Mathematics

A postdoctoral research assistant is required for three years to

work on the E.P.S.R.C.sponsored project ``Homoclinic Orbits and

Localised Buckling of Axially-Compressed Cylindrical Shells" supervised

by Dr. Alan Champneys in the Engineering Mathematics Department,

University of Bristol and Dr. Giles Hunt in the Department of Civil

Engineering, Imperial College, London. The Research Assistant would be

based at Bristol.

The project will combine numerical analysis, mathematical existence

theory and asymptotic methods to locate localised buckling solutions of

an elliptic system of partial differential equations modelling a long

thin cylinder. Heavy use will be made of numerical continuation methods

applied to an appropriately discretised boundary-value problem defining

an infinite cylinder, obtained via spectral methods and asymptotic

boundary conditions. Specific solutions will be selected from the

infinite family that can be shown to occur using homoclinic existence

theory applied to finite dimensional dynamical systems. An understanding

of these mathematical solutions in the context of structural engineering

will also be required, incorporating a comparison with asymptotic

solutions, a careful review of the existing experimental literature and

a small amount of phenomenological experimental work.

Applicants should have a strong mathematical background, expect to hold

a Ph.D. or have equivalent research experience in numerical analysis,

applied nonlinear analysis or dynamical systems theory and be willing to

work on an engineering mathematics application. Familiarity with

FORTRAN and Unix would be an advantage. The appointment will be at grade

4, or below, on scale 1A. Starting salary in the range: pounds 13941 --

pounds 15566. Start date October 1994 (negotiable).

Applications by letter and full C.V. including the name, address and

telephone number of two academic referees, should be sent to

Personnel Office (EO), Senate House, University of Bristol BS8 1TH

Closing date for applications Friday 22nd July.

Further details can be obtained from the Personnel Office

in writing or by telephone on (0272) 256450, or by

email from f.r.champneys@uk.ac.bristol. Please quote ref. no.C409
