**Subject: Matrices with Positive Eigenvalues**

Hi,

Let S be a symmetric positive definite matrix, and D a diagonal matrix

whose entries are in the interval [0,1]. Is the product DS positive

definite? In my numerical experiments it appears to be true. Apparently

the proof must be easy, but I was enable to find one.

[This problem is related to asymmetric Hopfield neural nets.]

Thanks in advance.

**Subject: New Book, Quasistatic Contact Problems**

International Press and the American Mathematics Society announce the

publication of Quasistatic Contact Problems in Viscoelasticity and

Viscoplasticity by Weiman Han and Mirceau Sofonea.

Description

Phenomena of contact between deformable bodies or between deformable and

rigid bodies abound in industry and in everyday life. A few simple

examples are brake pads with wheels, tires on roads, and pistons with

skirts. Common industrial processes such as metal forming and metal

extrusion involve contact evolutions. Because of the importance of contact

processes in structural and mechanical systems, considerable effort has

been put into modeling and numerical simulations.

This book introduces readers to a mathematical theory of contact problems

involving deformable bodies. It covers mechanical modeling, mathematical

formulations, variational analysis, and the numerical solution of the

associated formulations. The authors give a complete treatment of some

contact problems by presenting arguments and results in modeling,

analysis, and numerical simulations.

Variational analysis of the models includes existence and uniqueness

results of weak solutions, as well as results of continuous dependence of

the solution on the data and parameters. Also discussed are links between

different mechanical models.

In carrying out the variational analysis, the authors systematically use

results on elliptic and evolutionary variational inequalities, convex

analysis, nonlinear equations with monotone operators, and fixed points of

operators.

Prerequisites include basic functional analysis, variational formulations

of partial differential equation problems, and numerical approximations.

The text is suitable for graduate students and researchers in applied

mathematics, computational mathematics, and computational mechanics.

**Subject: New Book on Lanczos Algorithms**

SIAM is proud to announce the publication of _Lanczos Algorithms for Large

Symmetric Eigenvalue Computations; Vol. I: Theory_, by Jane K. Cullum and

the late Ralph A. Willoughby in our Classics in Applied Mathematics series.

First published in 1985, this book present background material,

descriptions, and supporting theory relating to practical numerical

algorithms for the solution of huge eigenvalue problems. This book deals

with "symmetric" problems. However, in this book, "symmetric" also

encompasses numerical procedures for computing singular values and vectors

of real rectangular matrices and numerical procedures for computing

eigenelements of nondefective complex symmetric matrices.

This book continues to be useful to the mathematical, scientific, and

engineering communities as a reservoir of information detailing the

nonclassical side of Lanczos algorithms and as a presentation of what

continues to be the most efficient methods for certain types of large-scale

eigenvalue computations. An online version of _Vol. II: Programs_, which

contains the FORTRAN code and documentation for each of the Lanczos

procedures discussed in Vol. I, can be found at the numerical analysis

community repository, www.netlib.org, under the term "lanczos."

SECOND ANNOUNCEMENT AND CALL FOR PAPERS

International Workshop on Computational Codes:

the Technological Aspects of Mathematics

advances in computing and software development for

Differential Equations

December 18-20, 2002

Universita' di BARI - Politecnico di BARI

http://www.dm.uniba.it/~mazzia/workshop/IWTAM/main.html

Sponsored by

Universita' di BARI

Dipartimento di Matematica, Universita' di BARI

Politecnico di BARI

GNCS (INDAM)

CNR (AGENZIA 2000)

SCOPE AND INTERESTS:

The active role of the Mathematics in sciences and technological

processes has been growing at an exponential rate in the last decades.

A great deal of such role is due to the construction of the so

called computational codes (sets of high integrated algorithms designed

for the solution on larger and larger classes of problems with an

easy user interface). Such codes are often commercialized well dressed

and full of gaudy utilities.

It is known that the whole Mathematics is the hidden part of our culture:

this portion of mathematics, although pervading all the applications,

risks to be even more hidden.

As Numerical Analysis, whose results are the ingredients of the

Codes, is a subject alive and rapidly growing, the evolution of the

Codes is a continuous process.

It is then necessary to make such activity, its limits as well as its

achievements, more visible, especially to the end users.

The scope of this meeting is then to bring together both specialists and

users (engineers, physicists, chemists, ...) to discuss about the state

of art and the new directions of this activity.

This will be also useful to collect ideas for updating, according to

the current requirements in real-life applications,

the TEST SET for IVP solvers (http://www.dm.uniba.it/~testset).

MAIN TOPICS:

Ordinary Differential Equations,

Differential Algebraic Equations,

Delay Differential Equations,

Boundary Value Problems,

Partial Differential Equations.
