Subject: Smale Prize Awarded

The Society for the Foundations of Computational Mathematics awarded
the first Smale Prize to Professor Snorre Christiansen at its FoCM'11
meeting in Budapest on July 14, 2011. Symbolic of the prize, Professor
Christiansen was given a G=F6mb=F6c, the first known homogeneous object
with one stable and one unstable equilibrium point.

The Smale Prize recognizes major achievements in furthering the
understanding of the connections between mathematics and
computation. The award is named after Stephen Smale who contributed
greatly to this understanding and many other fields of mathematics as
well as being key to the founding of the Society. The prize is awarded
to a researcher having received a doctoral degree within the 10 years
prior to the award.

Professor Christiansen of the University of Oslo, Norway, was awarded
the prize for his contributions to computational mathematics of
partial differential equations. Most of Professor Christiansen's work
is motivated by the design of numerical methods for various equations
arising in physics. The citation made particular note of his use of
Calderon=92s formulas to construct preconditioners for the electric
field equations, his contributions to the development of exterior
calculus and cohomological analysis of finite element methods, and his
convergence results for lattice gauge theory. Further information
concerning Professor Christiansen and the award ceremony can be found

The Society for Foundations of Computational Mathematics (FoCM) is a
nonprofit organization founded in 1995 that supports and promotes
research on foundations of computational mathematics. It fosters
interaction among mathematics, computer science and other areas of
computational science through its conferences, workshops and
publications. More information can be found at

Subject: Algebraic Multigrid Software

We are pleased to announce the release of AGMG 3.0, a software package
that implements an aggregation-based algebraic multigrid method.

AGMG comes either as a function that may be called from Matlab
environment, or as a Fortran 90 subroutine that may be linked with an
application program. Both versions have been designed to be easy to
use by non experts (in a black box fashion). A Fortran 90 parallel
implementation is also provided.

Version 3.0 is a major release that integrates our latest research
efforts. The aggregation procedure is now based on the explicit
control of some quality indicators. This allows to guarantee
theoretical convergence properties for some class of input matrices.
For general matrices, this makes the method more robust and the
convergence slightly faster on average than with the previous

Subject: New Book, Implicit Filtering

Announcing the August 11, 2011, publication by SIAM of:

Implicit Filtering, by C. T. Kelley

2011 / xiv + 170 pages / Softcover / ISBN 978-1-611971-89-7 /
List Price $65.00 / SIAM Member Price $45.50 / Order Code SE23

Implicit filtering is a way to solve bound-constrained optimization
problems for which derivative information is not available. Unlike
methods that use interpolation to reconstruct the function and its
higher derivatives, implicit filtering builds upon coordinate search
and then interpolates to get an approximation of the gradient.

The author describes the algorithm, its convergence theory, and a new
MATLAB=AE implementation, and includes three case studies.

This book is intended for students who want to learn about this
technology, scientists and engineers who would like to apply the
methods to real-world problems, and specialists who will use the ideas
and the software from this book in their own research.

Contents: Preface; How to Get the Software; Chapter 1 =96 Introduction;
Chapter 2 =96 Getting Started with imfil.m; Chapter 3 =96 Notation and
Preliminaries; Chapter 4 =96 Implicit Filtering Algorithm; Chapter 5 =96
Convergence Theory; Chapter 6 =96 Using imfil.m; Chapter 7 =96 Advanced
Options; Chapter 8 =96 Harmonic Oscillator; Chapter 9 =96 Hydraulic
Capture Problem; Chapter 10 =96 Water Resources Policy; Bibliography;

Subject: Math Biology Workshop, South Africa, Jan 2012

US-SA workshop "Mathematical Methods in Systems Biology and Population
Dynamics" African Institute of Mathematical Sciences, AIMS, Cape Town,
South Africa, January 4-7, 2012,

This workshop will bring together applied mathematicians with
researchers working in various biological and medical fields in order
to exchange ideas and advance research by initiating and promoting
collaborations motivated by challenging problems. These include the
spread of infectious diseases (epidemiology) or the growing need for
robust and reliable models in ecology, both of special importance in
the host country of South Africa, where research naturally has focused
on fighting disease and epidemics. In the US, on the other hand, a
strong emphasis exists on Systems Biology and especially on its
aspects related to cancer. Therefore a second focus area of the
workshop will be about improved and more realistic models for the
dynamic progression and treatment for various types of cancer, a truly
global challenging problem.

The workshop is expected to have an important educational impact
because of the unique character of AIMS, which is a center for
graduate studies in the mathematical sciences in Africa with emphasis
on mathematical biology. We particularly encourage the participation
of graduate students and junior researchers. We have some support from
local sponsors and as well as from the National Science Foundation and
the Society for Mathematical Biology.

If you are considering joining us for the workshop, for planning
purpose we would appreciate if you contact the organizers:
Jacek Banasiak --
Urszula Ledzewicz --
as soon as possible, but not later than September 15.
