Ralph Byers 1955-2007

After a long and hard fight against cancer, Ralph Byers passed away on
Saturday December 15.

Ralph received his bachelors degree in Mathematics from McGill
University in 1977 and his doctorate in Applied Mathematics from
Cornell University in 1983. He had been a professor of Mathematics at
Kansas University since 1987. Ralph was very well known for his work
in Numerical Linear Algebra, in particular on numerical methods for
eigenvalue and control problems.

Ralph was a very close friend of mine and I have worked intensively
with him for almost 25 years. He and his family spent two sabbaticals
in Germany at Bielefeld and Berlin and so did I at KU. We had many
mathematical projects going and we still talked mathematics just three
weeks ago.

Our community has lost a great scientist and many of us a very good friend.

Good Bye Ralph.

Subject: New book, Nodal DG-FEM: Algorithms, Analysis and Applications

Nodal Discontinuous Galerkin Methods: Algorithms, Analysis, and Applications
Jan S Hesthaven and Tim Warburton
Springer Texts in Applied Mathematics 54, Springer Verlag, New York.
ISBN: 978-0-387-72065-4
http://www.springer.com/west/home/math/cse?SGWID=4-10045-22-173736528-0

This book offers an introduction to the key ideas, basic analysis, and
efficient implementation of discontinuous Galerkin finite element
methods (DG-FEM) for the solution of partial differential
equations. It is the first text on DG-FEM that covers both theoretical
developments, practical implementation aspects, and general
applications, and it is suitable both as a textbook and for self study
with exercises included at the end of most chapters.

The text covers all main theoretical results, including an overview of
relevant results from approximation theory, stability and convergence
theory for numerical partial differential equations, and orthogonal
polynomials. The book describes in more detail DG-FEM discretizations
for a number of classic systems of time dependent partial differential
equations: Maxwell's equations, Euler's equations, the incompressible
Navier-Stokes equations as well as the static Poisson and Helmholtz
equations. The formulations and associated analysis are provided in
detail for one- and two- dimensions computations on general finite
element meshes with high-order elements, both in terms of analysis and
through complete algroithms in embedded Matlab software. The essential
details and Matlab functions for three-dimensional computations are
included and briefly discussed. The three appendices contain an
overview of orthogonal polynomials and associated library routines
used throughout the text, a brief introduction to grid generation, and
an overview of the included Matlab software.

The embedded software as well as many other related resources are all
freely available at the associated webpage: http://www.nudg.org.

Subject: One Day Workshop on Symmetry Preserving methods in CFD, Jan 2008

Please could you bring the following to the attention of any of your
colleagues/students who may be interested:
ONE-DAY WORKSHOP ON
Symmetry Preserving Methods in CFD and Beyond
Monday 14th January 2008
Black Horse House
Discretisations of partial differential equations (PDEs) in CFD
introduce numerical errors. It is important to preserve the geometric
symmetry of a flow field when non-aligned meshes are used, such as
planar wave symmetry on an irregular grid, or axial symmetry on a
Cartesian grid. In practice the degree of asymmetry is controlled by the
choice of numerical scheme and the stencil.

The governing PDEs also admit a wider class of symmetries that leave
them invariant, such as scale invariance or self-similarity, with
geometric symmetry a subset.

The ICFD workshop will provide an opportunity to review and discuss
symmetry preserving methods in CFD (based upon traditional schemes) as
well as newer research from the Geometric Integration community.
Invited speakers include

Chris Budd (University of Bath)
Alan Dawes (AWE Aldermaston)
Peter Hydon (University of Surrey)
Ben Leimkuhler (University of Edinburgh)
Elizabeth Mansfield (University of Kent)

The workshop will take place at the University of Reading on Monday 14th
January 2008, starting at 10.00 am with coffee. For details please see

MATHEON is looking for junior scientists who have proven their scientific
independence and who are building up their own research program. The initial
contract duration will be until May 31, 2010. After a positive evaluation, an
extension of the contract for a total of 6 years is possible. The position
includes funds to hire a research assistant, plus money for travel and
visitors. Salary will be on the BAT Ib level and, assuming appropriate

Subject: Ode to a Matrix

(The last posting of this was inadvertently
truncated and did not have the link).

Many NA Digest readers may be familiar with "Ode to a Haggis," by Robert
Burns, one of Iain Duff's favorite poets. I've translated the poem from
Scots into a more accessible dialect: Sparse-Matrese. Below is an
excerpt that might whet your appetite ... for both the poem, and a haggis
(oatmeal and entrails boiled in a sheep stomach, which tastes much better
than it sounds). For the complete poem, a glossary, and audio recordings
of both variants, see:

http://www.cise.ufl.edu/~davis/Poetry/Ode_to_a_Matrix.html

Ode to a Haggis, by Robert Burns (first 2 stanza only)

Fair fa' your honest, sonsie face,
Great chieftain o' the puddin-race !
Aboon them a' ye tak your place,
Painch, tripe, or thairm:
Weel are ye wordy of a grace
As lang 's my arm.

The groaning trencher there ye fill,
Your hurdies like a distant hill,
In time o' need,
While thro' your pores the dews distil

Ode to a Matrix, by Tim Davis (first 2 stanzas only)

Fair fa' your sparsest frontal mats,
Great chieftain o' the matrix-ranks !
Aboon them a' ye tak your fill,
Permute, factor, tril.
Weel are ye wordy of an ode
As lang 's Duff's code.

The groaning memory there ye fill,
Your cliques 's like a huge frontil,
