Subject: New Book on Fourier Analysis

Fourier Analysis:
An Introduction

Elias M. Stein and Rami Shakarchi

This first volume, a three-part introduction to the subject, is intended for
students with a beginning knowledge of mathematical analysis who are
motivated to discover the ideas that shape Fourier analysis. It begins with
the simple conviction that Fourier arrived at in the early nineteenth
century when studying problems in the physical sciences--that an arbitrary
function can be written as an infinite sum of the most basic trigonometric

Subject: Seeking Book on Integer and Combinatorial Optimization Algorithms

Dear NA readers,
I'm looking for a good book on integer and combinatorial optimization
algorithms. Searching the net has not been very fruitful due to an
overwhelming number of possible candidates...

The ideal book would be something like Numerical Recipes, but any book with
a practical flavour is ok.
Just to give an idea, something similar to the well known Luenberger for
linear and nonlinear optimization, which describe the theory behind the
methods but focuses mainly on algorithms.

Thank you in advance,

-- Davide Anguita

Subject: Workshop in College Park on Semiconductors and Biological Channels

A Workshop on

"Analysis and Numerics for Modeling
Semiconductor Devices and Biological Channels"

will be held at the Center for Scientific Computation And Mathematical
Modeling (CSCAMM) located at the University of Maryland, College Park on
May 19-23, 2003

SCIENTIFIC CONTENT. The last few years have witnessed rapid
developments in semiconductor mathematical research including modeling,
analysis and numerical simulations of semiconductor device equations,
ranging from the Schroedinger equation for the evolution of the electron
wave function to the drift-diffusion system for the evolution of the
'electron gas' which is close to a Maxwellian equilibrium. Like
semiconductor devices, many proteins and biological systems are also
devices in exactly the engineering sense of the word. These devices have
a definite function described by an approximate device equation that is
valid ONLY when the device is working as designed. Devices have complex
internal structure that allows them to have a reasonably robust and
simple equation and much of biological research is really an inverse
problem to determine the device equation.

The diversity of physical architectures for semiconductor devices and
biological ionic channels as well as the mathematical models they are
based on has proven to be a fruitful ground for interaction of
researchers from different disciplines in physics, biology, engineering,
mathematics and scientific computation.

We plan to revisit existing intersections and to explore future
directions in modeling, analysis and numerics of classical and quantum
transport in semiconductor devices, and classical transport in
biological ionic channels, and related topics.

A limited number of openings are available. To apply please RSVP at:

Subject: Special Issue of LAA on Positivity in Linear Algebra

Special issue on Positivity in Linear Algebra
Call for papers (Reminder)

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.
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.
