**Subject: 14th Leslie Fox Prize Winners**

The 14th Leslie Fox Prize Competition was held at Warwick

University on Monday June 29th 2009. This prize, which is

awarded every two years, recognizes the work of researchers,

under the age of 31 at the submission date, based on the

evaluation of a single paper and, for those who make the

final round, the presentation of that paper in a 40 minute

talk. From around 20 high quality submissions, the following

6 speakers made it to the final round and delivered talks

as follows:

Stefano Giani (Nottingham University)

"A convergent adaptive method for elliptic eigenvalue problems".

Daan Huybrechs (Katholieke Universiteit Leuven)

"On the Fourier extension of non-periodic functions".

Armin Lechleiter (Ecole Polytechnique)

"The factorization method is independent of transmission eigenvalues".

Colin B. Macdonald (Mathematics, UCLA)

"The implicit closest point method for the numerical solution of partial

differential equations on surfaces".

Brian D. Sutton (Randolph-Macon College)

"Computing the Complete CS Decomposition".

Liuqiang Zhong (Xiangtan University)

"Optimal multilevel and adaptive finite element methods for

time-harmonic Maxwell equations."

Brian Sutton was awarded a first prize, and the remaining speakers

were all awarded a second prize. The 15th Leslie Fox Prize

competition will take place in Manchester in 2011.

The prize was established in 1985 by the (UK) Institute for

Mathematics and Its Applications. It is sponsored by

Cambridge University Presss, Oxford University Press,

Princeton University Press, SIAM and Springer.

I have a number of volumes of Mathematics of Computation and I want to

Stellar: A Tetrahedral Mesh Improvement Program

Bryan Klingner and Jonathan Shewchuk

Department of Electrical Engineering and Computer Sciences

University of California, Berkeley

Stellar improves tetrahedral meshes so that their worst tetrahedra

have high quality, making them more suitable for finite element

analysis. Stellar employs a broad selection of improvement

operations, including vertex smoothing by nonsmooth optimization,

stellar flips and other topological transformations, vertex insertion,

and edge contraction. If the domain shape has no small angles,

Stellar routinely improves meshes so that the smallest dihedral angle

is larger than 30 degrees and the largest dihedral angle is smaller

than 140 degrees.

Features include a choice of several quality measures (both as

objective functions and for mesh statistics), control of tetrahedron

sizes, and transformations that improve the boundary of the mesh. The

last give you a choice between flat surfaces (in which vertices are

constrained to lie, so the surface is improved without changing the

domain shape) and curved surfaces (where we optionally permit small

changes of the domain shape if they give big wins in mesh quality).

Stellar is written entirely in ANSI C, and relies only on standard C

libraries. It should compile on any POSIX-compliant system, and is

known to compile on Linux, Mac OS X, and Microsoft Windows. Stellar's

internal mesh data structure is an implementation of Blandford,

Blelloch, Cardoze, and Clemens' "Compact Representations of Simplicial

Meshes in Two and Three Dimensions". For geometric computations, it

relies on our fast robust predicates code. It is available under the

terms of the Berkeley Source Distribution (BSD) license. It is

accompanied by a (slightly unfinished) visualization program called

Show Me, which runs only under X Windows.

algorithms, please visit http://www.cs.berkeley.edu/~jrs/stellar/ .
