**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.

FIRST ANNOUNCEMENT - CALL FOR PAPERS

This conference continues the series of scan-symposia

which have previously been held at Karlsruhe, Basel,

Albena, Oldenburg, Wien, Wuppertal, Lyon, and Budapest

under the joint sponsorship of GAMM and IMACS. These

conferences have traditionally covered the numerical

and algorithmic aspects of scientific computing, with

a strong emphasis on validation and verification of

computed results as well as on arithmetic, programming,

and algorithmic tools for this purpose. The objectives

are to propagate current applications and research as

well as to promote a greater understanding and increased

awareness of the subject matters.
