From: Roman Wienands 
Subject: New Book: "Practical Fourier Analysis for Multigrid Methods"

I'm pleased to annonce that the following book is available:

Roman Wienands and Wolfgang Joppich:
"Practical Fourier Analysis for Multigrid Methods",
CRC Press, 2004, pp. 240, ISBN 1-5848-8492-4,
USD 79.95 / GBP 44.99.
(http://www.crcpress.com/)

Before applying multigrid methods to a project, mathematicians, scientists,
and engineers need to answer questions related to the quality of convergence,
whether a development will pay out, whether multigrid will work for a
particular application, and what the numerical properties are.  Practical
Fourier Analysis for Multigrid Methods uses a detailed and systematic
description of local Fourier k-grid (k=1,2,3) analysis for general systems of
partial differential equations to provide a framework that answers these
questions.

This volume contains software that confirms written statements about
convergence and efficiency of algorithms and is easily adapted to new
applications.  Providing theoretical background and the linkage between theory
and practice, the text and software quickly combine learning by reading and
learning by doing.  The book enables understanding of basic principles of
multigrid and local Fourier analysis, and also describes the theory important
to those who need to delve deeper into the details of the subject.

FEATURES

# Provides a theoretical framework necessary for the successful use of
multigrid methods for (systems of) partial differential equations
# Allows for local Fourier analysis via a simple mouse click, courtesy of
accompanying software (LFA) and GUI (xlfa)
# Includes case studies for two- and three-dimensional problems, including
Poisson, convection diffusion, and biharmonic equation, the Oseen and Stokes
equations, a linear shell problem and elasticity systems
# Presents the recently-developed three-grid analysis, allowing investigation
of real multigrid effects

From: "Anna-Karin JONSSON" 
Subject: Thesis: On Multiresolution + Turbulence + Combustion 

For those interesting in implemented the multiresolution approach, wavelets,
etc in turbulent flows and the possibility to extend it to combustion, a
100-pages MSc thesis has been written by Raul MACHADO Garcia, which includes
146 references.  Many ideas and open issues are left for further work since
the author has moved to other research areas.  Several several hard copies
have been sent for further distribution to ITM, RWTH-Aachen, Germany, where
the combustion part of the thesis was done.  The address is:

    http://www.itm.rwth-aachen.de/Deutsch/Mitarbeiter/Norbert.Peters/norbert.peters_eng.html

The abstract of the thesis is given below.  The aim of this work is to

i) insert some multiresolution properties in the premixed turbulent combustion
context
ii) indicate the advantage of the multiresolution in the study of turbulence,
its possible extension to combustion and to level-set and G-equation,
iii) explain the importance of the eigenvalue problem in combustion,
iv) aboard the significance of strongly corrugated flame front in the study of
flame front dynamics,
v) recognize the Willems model as a particular case of the Speziale model in
the multiresolution perspective,
vi) derivate and implement the filtered G-equation based on the level-set
formulation,
vii) give a glimpse on the Fast Marching Method for the G-equation,
viii) run and show the results of a 3D vessel case using Very Large Eddy
Simulation (VLES),
ix) give the closure needed in the model of the equation for the flame surface
area ratio using VLES,
x) point out some algorithms with the potential of decreasing the
computational costs in GMTEC (General Motors CFD code) as well as other
similar unstructured CFD (combustion) codes.

The long-term program of this Special Semester will involve a community of
renowned researchers in the field of Computational Mathematics and
Computational Mechanics.  We encourage young scientists, who are in the early
stages of their career (recent PhD's) but also graduate students to apply for
participation.  We are especially interested in applicants who intend to
participate in the entire program (October 3 - December 16, 2005).  However,
the attendance of single special events or block seminars is also possible.
Depending on need and qualification full or partial support for long-term
participants is available.  Applicants should give the name of three persons
who can be contacted for reference.  Applications with Personal and Scientific
CV, list of publications, and a short statement about scientific interests
related to the Special Semester should be sent to:
