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.

Subject: A home for some issues of Mathematics of Computation

I have a number of volumes of Mathematics of Computation and I want to
give them away. I have Volumes 21 (1967) thru 43 (1984) and want to do
something other than toss them into the trash to be recycled. Are you
interested or do you know of someone who would be interested?

Subject: Announcing Stellar: A Tetrahedral Mesh Improvement Program

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 .

Subject: 2 PhD positions in Isogeometric method for PDEs, RICAM, Linz, Austria

Description of the project and positions:

Applications are invited for 2 PhD students in the field of
"Computational Methods for Direct Field Problems", at Johann Radon
Institute for Computational and Applied Mathematics (RICAM), Linz,
Austria. These positions are part of the Austrian Science Fund (FWF)
project "Isogeometric method for partial differential equations", led

starting gross income (~1767.80 Euro) includes social security
(pension), health care coverage, and unemployment benefits. Some
additional funds will also be available for research purposes
(conference participation, research visits abroad, etc.). Apart from
the standard computing resources, e.g. a personal laptop or a
workstation with all the necessary softwares for routine work, access
to large-scale machines are also available whenever required.


For both positions a master's degree in applied/computational
mathematics or a closely related field is required with excellent
grades. The applicants must have a good understanding of numerical
solution techniques, e.g. (discontinuous-Galerkin) finite element
methods, for partial differential equations. Due to the computational
nature of the project, high-level of programming skills (in
fortran/c++/matlab) is also required. Additionally, some background in
mesh generation (and/or computer aided geometry design) for the first
PhD position, and in linear algebra and iterative solvers (e.g.
multigrid / multilevel methods) for the second PhD position, will be
highly desirable. Apart from a strong interest in the above-mentioned
work, the applicants should be highly motivated in learning new topics
related to their work.

The application material will consist the following documents:

(1) A concise application letter (max 1 page) describing yourself,
research interests, and motivations for joining the project, and the
curriculum vitae (single file of both)

(2) Scanned image of the master's degree certificate (aggregate grade
as well as grades obtained in each course should be mentioned in the
CV if not listed in the certificate),

(3) Two letters of reference, one from the Master thesis supervisor,
and one from the instructor of the course (candidate's strongest

PDF files of all of these documents should be sent by email (no paper
application) to satyendra.tomar @, with a cc to @, with the subject "Applications for IMPDE
position 1" or "Applications for IMPDE position 2" (depending on the
interest) by 16th Aug. Though all the applications will be
acknowledged, however, only the shortlisted candidates will be
contacted further for interviews before the end of Aug. The interviews
will be held in the first week of Sep, and the positions will be
offered by 14th Sep. The selected candidates are expected to join by
1st Oct or as soon as possible thereafter.
