Subject: Wilkinson Prize for Numerical Software
We are pleased to announce that the 1999 Wilkinson Prize for Numerical
Software has been won by Matteo Frigo and Steven Johnson of MIT for
FFTW. The presentation was made by Richard Field, Vice Principal of the
University of Edinburgh and Chairman of NAG, at ICIAM'99 in Edinburgh on
July 8th.
FFTW (the "Fastest Fourier Transform in the West") is a library of C
routines for the computation of the discrete Fourier transform of real
and complex data, that tunes the computation automatically for any
particular hardware platform to produce highly efficient code. Further
information on FFTW can be found on www.fftw.org.
The Wilkinson Prize was established to honour the outstanding
contributions of James Hardy Wilkinson to the field of numerical
software, with the aims of encouraging young researchers to turn their
ideas and algorithms into quality software, and to help give the
researchers the recognition that their work in producing such software
deserves. The Prize is sponsored by Argonne National Laboratory, the
National Physical Laboratory and the Numerical Algorithms Group.
The previous winners of the Prize are Linda Petzold for DASSL, and Chris
Bischof and Alan Carle for ADIFOR 2.0.
We congratulate the winners and thank all those who submitted entries
for the 1999 Prize.
Wilkinson Prize Committee.

Subject: New Book, Anisotropic Finite Elements
It is my pleasure to announce my book
Thomas Apel:
Anisotropic Finite Elements: Local Estimates and Applications
Book Series: Advances in Numerical Mathematics
Teubner, Stuttgart, 1999. 264 pp. ISBN 3-519-02744-5
Anisotropic finite element meshes have different mesh sizes in
different directions. Such meshes have a great potential for the
approximation of functions with anisotropic behaviour, as for
example near edges or in boundary layers. The aim of this monograph
is to present a mathematical theory of the approximation properties
of finite element spaces over anisotropic meshes. Local error
estimates are derived for the Lagrange interpolation and for modified
Scott-Zhang interpolation operators. Families of anisotropic finite
element meshes are constructed for the numerical solution of model
problems with boundary layers or edge and corner singularities, and
the global discretization error is estimated. Numerical tests show
that the asymptotic results are valid for a moderate number of
unknowns already.
The strengths of this investigation are the consideration of two- and
THREE-dimensional problems in GENERAL polygonal/polyhedral domains,
and the treatment of lower and HIGHER order finite elements.
The contents:
* Introduction to anisotropic finite elements,
* Lagrange interpolation on anisotropic elements,
* Scott-Zhang interpolation,
* Anisotropic finite element approximations near edges,
Diffusion problems in domains with corners and edges,
* Boundary layers in convection-diffusion-reaction problems.
