**Subject: l(infinity) Algorithm**

Hello,

I am currently interested in designing an algorithm for the l_infinity

problem (Chebychev, minimax) and I need some algorithm to compare with.

If possibe, I want copies of the famous Barrodale-Phillips and

Conn-Bartels and Charalambous algorithm. Also if there is any other

efficient algorithm, I would like to have information about it.

Yours sincerely

**Subject: Elliptic PDE Solver **

Hi,

I am looking for a solver for the 3D self-adjoint elliptic PDE :

div[E(x,y,z)*grad(U(x,y,z))] = R(x,y,z)

where E & R are user-specified functions. I am interested in

Cartesian as well as cylindrical coordinates.

Any suggestions or source code will be appreciated.

Thanks in advance.

**Subject: Question on Kronecker Products**

Hi,

I have a question related to minimization of a function involving kronecker

products and I can't seem to be able to crack it. I've looked in lots of

matrix analysis books for similar problems with little luck. I was

wondering if anyone had seen something similar to the problem I will pose

below.

Convention:

lower case letters -- vectors (or scalars, if specified)

upper case letters -- matrices

a^H -- conjugate transpose of 'a'

.kron. -- symbol for kronecker product of 2 matrices

Problem formulation:

minimize f(p,u) = (p^H .kron. u^H)*(E*E^H)*(p .kron. u)

subject to p^H*p = 1

and u^H*u = 1

'p' -- m x 1

'u' -- n x 1

'E' -- mn x k

Any insight or suggestions on this problem would be greatly appreciated.

Thank you.

**Subject: New Book on Total Positivity**

New book on the applications of Total Positivity.

The book Total Positivity and its Applications, (ISBN

0-7923-3924-X) has just been published by Kluwer Academic

Pub., Dordrecht, The Netherlands, in the series Mathematics and

its Applications. Edited by Mariano Gasca and Charles A.

Micchelli, the volume (about 500 pages) contains articles that

document the advances in the subject of Total Positivity during

the last two decades.

The material is divided into ten chapters: Spline

Functions, Matrix Theory, Geometric Modeling, Probability and

Mathematical Biology, Approximation Theory, Complex

Analysis, Statistics, Real Analysis, Combinatorics and Integral

Equations. Some of the articles are of a survey nature and

others present new results.

The book, dedicated by the editors to Prof. S. Karlin, author of

the influential treatise Total Positivity (Stanford U. Press) in

1968, is the result of an international meeting held in Jaca

(Spain) in September 1994. It is expected that the book will

be of value to mathematicians, engineers and computer

scientists whose work involves applications of Total Positivity.

NEW BOOK ANNOUNCEMENT:

Algorithms for Linear-Quadratic Optimization

by Vasile Sima

Vol. 200 in "Monographs and Textbooks in Pure and Applied Mathematics"

Earl J. Taft and Zuhair Nashed (Series Editors).

Publisher: Marcel Dekker, Inc., New York

March 1996 / 384 pages, illustrated / Hardcover / ISBN 0-8247-9612-8

This book offers valuable theoretical, algorithmic, and computational

guidelines for solving the most frequently encountered linear-quadratic

optimization problems, providing an overview of recent advances in

control and systems theory, numerical linear algebra, and optimization.

It covers fundamental issues in control theory and applications, such

as regulator and estimator design, state estimation, and robust control.

Topics of special interest, including H-infinity and H-2 optimization,

defect correction, stability-enhancing scaling procedure for Schur

Riccati solvers, Hammarling's algorithms for non-negative definite

Lyapunov equations, ordering generalized real Schur forms, structure-

preserving techniques, finding eigenvalues of Hamiltonian matrices,

and multishift algorithms, are highlighted. Theoretical treatment

benefically combines with an insight into algorithmic techniques,

with relevant numerical issues, advanced software tools, implementation

details improving performances, practical recommendations, and solution

of specific problems.

The chapters have a similar organization: basic theory (with short

proofs); mathematical and computational problem(s); and associated

numerical solvers. Each particular solver has the following referred:

algorithmic templates; computational issues; applicability and

limitations. To be as self-contained as possible, the book includes

and examines state-of-the-art numerical linear algebra algorithms and

associated software tools, like LAPACK. All algorithms are written in

a suggestive and concise informal language, that facilitates computer

implementation.

A summary of extensive numerical comparisons of various algorithms

is included. Many worked numerical examples, based on published

industrial models, are used for illustrative purposes. The book also

contains 20 figures, 11 tables, an index of algorithm definitions

(with over 80 entries), a subject index, and about 300 references.

By its emphasis on the latest algorithmic advances and areas of current

research interest, as well as by its broad coverage, methodological

guidances and practical guidelines, the book could be useful to applied

and industrial mathematicians, control engineers, electrical and

electronics engineers, computer programmers, researchers in automatic

control and dynamical optimization, and graduate students in these

disciplines.

**Subject: New Book on Singularly Perturbed Diffferential Equations**

Springer-Verlag have just published the book

"NUMERICAL METHODS FOR SINGULARLY PERTURBED DIFFFERENTIAL EQUATIONS

Convection-Diffusion and Flow Problems"

by Hans-Goerg Roos, Martin Stynes & Lutz Tobiska.

Springer Series in Computational Mathematics No. 24

Published March 1996 in Heidelberg, Germany, ISBN 3-540-60718-8,

350 pages, cost 148 DM.

This book collects, explains and analyses basic methods and recent

results for the successful numerical solution of singularly perturbed

differential equations. Such equations model many physical

phenomena and their solutions are characterized by the presence of layers.

The book is a wide-ranging introduction to the exciting current literature

in this area. It concentrates on linear convection-diffusion equations and

related nonlinear flow problems, encompassing both ordinary and

partial differential equations. While many numerical methods are considered,

particular attention is paid to those with realistic error estimates.

The book provides a solid and thorough foundation for the numerical analysis

and solution of singular perturbation problems.

LBNL Mathematics Department are active. Among these

areas are computational mathematics, turbulence theory, material

sciences, interface methods, fluid mechanics, adaptive grid methods,

iterative methods, numerical linear algebra, and tools for parallel

processing. NERSC will provide access to a 512 processor Cray T3E, and

there will be opportunities to interact with the Mathematics faculty and

Computer Science faculty at the nearby University of California, Berkeley.

(for more information see http://www.lbl.gov/NERSC/ on the WWW).
