**Subject: Iterative Methods for a Structured Linear System**

Hi,

I am interested in a linear equation system having the coefficient matrix

[M (u+v)]

[(u-v)^T beta]

The matrix M is positive definite and symmetric, u and v are vectors and

beta is scalar. This system is almost symmetric but not quite.

[Due to the special structure in the problem I might be able to prove

M - (u+v)(u-v)^T/beta

is positive definite. I do not know if that is of any use.]

What would be the best iterative method. I think conjugate gradient cannot be

used. QMR could be the answer. However, is there a method would exploit the

near symmetry and the problem structure?

[This has application in optimization alg. for linear and convex problems.]

Thanks.

**Subject: Reprinted Book, Extrapolation Methods, Theory and Practice**

Dear NA community,

we are happy to inform you of the 1st reprint of the book

C. Brezinski, M. Redivo Zaglia

Extrapolation Methods. Theory and Practice

North-Holland, Amsterdam, 1991

x + 464 pages

ISBN: 0-444-88814-4

This book contains a 3.5" (instead of a 5.3" as in the first edition)

diskette with FORTRAN programs and subroutines of many convergence

acceleration methods.

In numerical analysis, applied mathematics and engineering, many methods

produce sequences and series. When the convergence is slow, the sequence

can be transformed, by an extrapolation method, into a new sequence

converging faster, under some assumptions, to the same limit.

This volume presents the theory of such convergence acceleration methods,

with applications, numerical results, and the corresponding software.

The contents is: introduction to the theory, scalar extrapolation

algorithms, special devices, vector extrapolation algorithms, continuous

prediction algorithms, applications, software.

**Subject: Special Issue of Linear Algebra and its Applications**

LINEAR ALGEBRA AND ITS APPLICATIONS

Special issue on Positivity in Linear Algebra

Call for papers

Positivity in linear algebra arises in many different forms and flavors.

It includes the study of matrices with nonnegative entries

(Perron-Frobenius theory), matrices with positive principle minors

(P-matrices, positive definite matrices, totally positive matrices), as

well as linear maps with characteristics that generalize or combine these

notions of positivity (e.g., positive operators, cone preserving maps).

The applications of positivity as a linear algebraic notion are indeed

numerous, ranging from the physical and social sciences to other

mathematical areas like graph theory, optimization, stochastic processes,

statistics, dynamical systems and numerical analysis. The benefit is

mutual as many advances in these areas are being achieved with the aid of

linear algebra and its notions of positivity, which in turn are enriched

by ideas, challenges and goals for the future.

For this special issue, we are looking for papers that primarily advance

knowledge about positivity in linear algebra and the associated matrix

classes, or that extend the reach of their theory in applications and in

other mathematical fields.

Areas and topics of interest include, but are not limited to the

following:

Entrywise positive (nonnegative) matrices.

M-matrices and their inverses.

Eventually nonnegative matrices.

Positive (semi-)definite matrices.

Totally positive (nonnegative) matrices.

P-matrices.

Cone preserving maps.

Positive stability.

Generalizations of the above in the context of operator theory

and matrix functions.

All papers submitted must meet the publication standards of Linear Algebra

and its Applications and will be refereed in the usual way. They should be

submitted to one of the special editors of this issue listed below by 31

August 2003.
