**Subject: Complex ODE Solver**

Dear All,

I am trying to solve a system of N complex nonlinear ordinary

differential equations arising from complex wavelet-Galerkin projection of

Burgers equation. Is there any direct numerical code in Fortran77 to

perform this task in complex variables algorithm without resorting to the

splitting of variables and matrices into real and imaginary parts to form

2N real odes ? Many thanks.

Regards,

Sithi

**Subject: Complex Analogues of Householder Reflections**

It is customary in numerical linear algebra texts to do things

with real matrices until eigenvalues are reached, at which point

it is reluctantly admitted that complex numbers are unavoidable.

The Hermitian transpose is introduced, you tell the students that

this is the true and correct definition of which the ordinary

transpose is merely the real special case; a few theorems that

really need unitary rather than orthogonal matrices (Schur's lemma,

unitarily diagonalizable <==> normal) are proved; and the brief

flirtation with complex matrices is over.

Students are left with the impression that you can everywhere simply

replace 'transpose' by 'Hermitian transpose' and all theorems will

remain true --- an impression which is reinforced by having Matlab

available, which works with complex matrices and Hermitian transposes

as a natural way of life.

This works well most of the time, but it does not work with Householder

matrices the way they are usually introduced. All the books I have

consulted use some inessential variation on the definition

(1) H = I - 2*u*u' where norm(u)=1.

(I'm using Matlab notation on purpose --- of course most of the books

say u^T, not u^H, and work only with real u.)

Some of the pleasant applications of Householder matrices are no longer

true in the complex case, e.g.

1. For any two distinct vectors x and y of equal length, there

exists a unique Householder matrix H such that H*x = y.

2. For any unit vector x except x=[1;0;0;...;0], there exists a

unique Householder matrix with x as its first column.

(1) is true only when x'*y is real, (2) only when x(1) is real.

These facts are presumably well known to those who actually write

codes for complex matrices (the computer is a much more unforgiving

rejector of sloppy thinking than the typical undergraduate) but I

found them out the hard way, having practically on the spur of the

moment having written Hermitian transposes instead of ordinary ones,

and discovering on my feet in front of a class that the old proofs

no longer work, for the simple reason that the old theorems are no

longer true.

Perhaps the proper way to define elementary unitary matrices is:

(2) H = (I-P) + w*P where P is a 1-dimensional orthogonal projector

and abs(w)=1.

Now in the real case H may equal I, which allows one to remove 'distinct'

and 'except x=[1;0;0;...;0]' from the two lemmas above, and in the

complex case the two lemmas are now true without further qualification.

All that is lost is the term "Householder reflection": (2) is a

reflection only when w=-1.

If anyone knows a textbook that does treat elementary unitary matrices

in this way, I would be delighted to hear of it -- I may consider

switching texts!

**Subject: New Book on Finite Elements**

NEW BOOK ANNOUNCEMENT:

FINITE ELEMENTS: Theory, fast solvers, and applications

in solid mechanics

Dietrich Braess

translated from the 2nd German Edition by

Larry Schumaker

hardcover ISBN 0-521-58834-0 Cambridge University Press

softcover ISBN 0-521-58187-7 Cambridge University Press

German 2nd ed ISBN 3-540-61905-4 Springer-Verlag

The book is directed to graduate students in mathematics and to young

researchers. We take into account that most of the research is now

concentrated on finite elements for hard problems and on the fast

solution of the resulting equations. Therefore the nonconforming

elements and saddle point problems get as much space as the conforming

elements. Moreover we treat the method of conjugate gradients and

multigrid methods. Finally we present an introduction to the

application of finite elements in solid mechanics which up to now

does not exist in textbooks in a similar way.

Many facts in finite element theory are counterintuitive for students

who have studied ordinary differential equations before.

We try to avoid that the reader overlooks the counterintuitive

or unexpected arguments.

People who have used the German edition for their lectures like

especially an example with a tent in connection with the trace theorem

for Sobolev spaces. But we find counterintuitive things at all levels.

Just recently it has turned out that saddle point problems with penalty

terms have a different behavior than one from folklore.

The book has 6 chapters:

I. Introduction

II. Conforming Finite Elements

III. Nonconforming and Other Methods

IV. The Conjugate Gradient Method

V. Multigrid Methods

VI. Finite Elements in Solid Mechanics

We intend to establish later a www page with additional remarks

and a list of misprints.

The Chair for Applied Mathematics I of the Friedrich-Alexander-University

Erlangen-Nuremberg, Germany offers a three-year research position which

is connected with a research project in applied mathematics.

The project is funded by the German Federal Research

and Education Department. It deals with model, algorithm and software

development for the prediction of unsaturated subsurface contaminant

transport and remediation strategies. The transport processes are modelled

by nonlinear partial differential equations. (Further details may

be found at: <http://www.am.uni-erlangen.de/...>.)

The research project is embedded in a Ph D programme on

applied mathematics / scientific computing.

The ideal candidate has a degree in mathematics or a similar

subject. He should be familiar with applied mathematics / scientific computing

and/or partial differential equations.

Knowledge of the German language is not expected and only necessary as far

as everyday life is concerned.

Salary is according to the German BAT IIa/2 tariff. It includes payments

for social security, health care and benefits and depends on age and

family status. (A 25 year old unmarried person receives about

DEM 33,000 / US$ 20,000 gross payment per annum.)

Candidates should contact me as soon as possible, and provide their CV

and a description of their scientific background and interests.

Bereits vorhandene Loesungsmethoden, wie Finite--Volumen--, Finite--Elemente--

oder Finite--Differenzenverfahren, sollen beschleunigt werden. Darum soll eine

neue Loesungsmethode, aufbauend auf dem von Harten vorgeschlagenen

Multiskalen--Konzept entwickelt und implementiert werden. Die theoretische

Grundlage dieser Ansaetze bilden stabile Multiskalenbasen und Wavelets.

Weitere Informationen finden Sie unter

and experimentalists testing the predictions of the models in laboratory

apparatus and in actual fabrication lines for silicon devices. Effective

communication skills and a broad range of interests are essential.

The position is jointly funded by the NSF Divisions of Mathematical

Sciences and Materials Research, and by the DARPA Defense Sciences

Office. A recent Ph.D. is required. The starting date is negotiable,

but no later than Sept. 1 1997, and is funded for two years. The position
