Subject: About Matrix A+uv'
Dear NA readers:
I came across the matrix A+uv', where A is square matrix, u and v are
vector.
The first problem of mine is how to measure the L2 norm of this matrix. In
other words, to what extent the second term uv' affects the L2 norm of such
a sum. Of course, we easily establish
norm(A+uv') <= norm(A) +norm(u)norm(v)
However, I would like to know some more elaborate results.
The second problem is that if matrix A is positive definite matrix, under
what conditions A+uv' will preserve this feature. Similarly, if A is
negative definite matrix, how will A+uv' deteriorates the negative definite?
Any information and suggestion will be highly appreciated.
Yours sincerely,
Wen CHEN

Subject: Finite Element Shape and Condition Number
The following question came up recently in the context of mesh generation
for use in simulation and computer graphics:
"Do you know of any (preferably gentle) references in which the effect of
element shapes on the condition number of a finite element stiffness matrix
is written out explicitly? I would be very happy just to see this in the
context of the Poisson problem with bilinear basis functions. I would like
to see an equation which makes me say "Oh yeah, now I see why we want aspect
ratios close to one, or why large aspect ratios or very small angles are
bad."
(Scott Cohen, Stanford U.)
Michael Holst (mholst@math.ucsd.edu) contributed this:
If you look in e.g. Axelsson and Barker,
you will find that you can derive a bound on the L2 norm of the interpolant
error in terms of the smallest angle theta in the entire mesh,
which looks like:
|| u - u_I ||_{L^2} <= C / [ sin(theta) ] * h^2 | u |_{H^1}
This 1/sin(theta) then feeds into the condition number via the bound on
the largest eigenvalue of the stiffness matrix. As theta gets small,
1/sin(theta) blows up. Now, you have to be a little careful here is these
are just inequalities; you don't necessarily know that the error really
does blow up, only that your bounds do. In fact, for problems which have
a serious flow direction, you can show that long thin elements do in fact
give the right approximation properties, even if the normal error analysis
bounds blow up. However, the above inequality does reflect the
approximation failure for isotropic settings.
In 3D, you can come up with a similar characterization in terms the ratio
of the diameter of inscribing and circumscribing spheres rather than minimal
angle (you can probably come up with a solid angle condition as well).
If you want to see the basic condition number estimate in terms of error
estimates, you can find this in my Phd thesis (on my web page, title is
"The Poisson Boltzmann equation: analysis and multilevel numerical soln")
on something like page 54 or 55.

Subject: Math Software That Runs in Web Browser
Elements Engineering-Scientific Workspace Software
Elements is a general purpose mathematics and plotting
tool that runs inside the Microsoft IE4 browser. It
facilitates the sharing of mathematical documents and
ideas over the Internet.
Elements syntax is much like standard JavaScript, but
includes math data types: Scalar, Vector, Quaternion,
Matrix, Polynomial, Function, File, and Expression.
Elements has many special math operators, and hundreds
of built-in functions and manifolds. Most functions are
templates. Each returns whatever data type naturally
results from its input arguments.
Elements' working document accepts your commands
on the bottom line. All other lines are editable. Even
embedded plots are editable. You can write your own
scripts and functions. By posting your scripts at a web
site, anyone with Elements installed can run your
scripts in their IE4 browser.
Elements' capabilities are summarized in table
http://www.elesoft.com/eletable.html.
Example 2D plots are at
http://www.elesoft.com/eleplot.html.
Example surface plots, some with geodesics, are at
http://www.elesoft.com/elerend.html.
Elements provides special geodesic computation and
visualization. This is the same Geodes software stored
in the Netlib Repository.
http://www.elesoft.com/geodes.html
Elements also runs as an ordinary Microsoft Windows
application. The new browser capability uses ActiveX
document technology. For a listing of Elements'
distinctive software technologies, read
http://www.elesoft.com/elecmp.html.
A trial and evaluation Lite Edition is freely available
by Web download. A modestly priced Professional Edition
with more capabilities is also available. Either product
can be selected from Web page
http://www.elesoft.com/download.html
Elements downloads and installs automatically in about
5 minutes using a 28.8K modem with a fast connection.
One demo computes and plots 27 famous historical
curves, including Pascal's Limacon and Fermat's Spiral.
I hope Elements' new browser capability provides a new
way for you to share mathematical ideas over the
Internet. I welcome your suggestions on how to improve
this product.
Thank you,

Subject: NetSolve Version 1.2 Now Available
NetSolve version 1.2 is now available (http://www.cs.utk.edu/netsolve/).
NetSolve is a software environment for network computing that combines
distributed computational resources into a unified service for solving
complex scientific problems remotely. Using a client-agent-server
paradigm, it aggregates the hardware and software resources of any
number of computers that are loosely connected across a network and
offers up their collective power through client interfaces that are
familiar from the world of uniprocessor computing. When a user wants a
certain computational task performed, he or she can use any one of a
number of conventional software clients (e.g. MATLAB, Mathematica,
simple procedure calls) to contact an agent with the request. The agent
keeps track of information about all the servers in its resource pool,
including their availability, load, network accessibility, and the range
of computational tasks they can perform. The agent then selects a server
to perform the task, and the server responds to the client's request. A
load-balancing policy is used to manage computational resources to
ensure good performance and simple retry provides fault-tolerance.
NetSolve has been ported to every major UNIX platform. The NetSolve
client is now available from C, Matlab and Mathematica interfaces on the
MS-Windows platform, and both the agent and server components will soon
be available for NT. The following numerical and scientific libraries
have been integrated into NetSolve computational servers: ARPACK, BLAS,
FFTPACK, FitPack, ItPack, LAPACK, MinPack, PETSc, and ScaLAPACK. These
numerical libraries cover several fields of scientific computing; Linear
Algebra, Optimization, Fast Fourier Transforms, etc. This list includes
only the software that has been integrated by the NetSolve team, but it
continues to grow. Adding new software libraries to NetSolve servers is
relatively straightforward and users have added special libraries for
their own purposes.

Subject: 3D Singular Elements
Dear Colleagues,
We are happy that at long last we have achieved the fast and reliable
computer realization for obtaining singular terms at polyhedral
corner points of solids, including for materials joints.
As is well known, the singularity of a solution at corner points may
worsen the convergence and accuracy of BEM/FEM very much. In 2D those
difficulties are reduced essentially by using explicit singular
expansions near the points (weight functions, singular elements etc).
However, in 3D the orders of singularity and angular functions cannot
be obtained so easy as in 2D since they are spectral points and
eigensolutions of the correspondent PDE or BIE operators.
We have been developing a semi-analytical method of the 3D singular
characteristics obtaining via converting the initial BIEs into the
1D integral equations by the Mellin transform. Though the final step
requires iterative searching for the roots and eigenvectors, it takes
so little computing time that the expansion obtained may be treated
as an analytical one. More details about the method may be found in
the paper
E.Glushkov, N.Glushkova and O.Lapina, 3D Elastic stress singularity
at polyhedral corner points. Int. Journal of Solids and Structures,
1999, Vol. 36, pp. 1105-1128.
Now we are thinking over possible applications of the results.
They may be
1) introducing the 3D singular elements into existing or
developed packets;
2) fracture problems, contact problems, wave diffraction by edges
and corner points etc.
Proposals of applications and co-operation are welcome.
Yours sincerely,

SYMPOSIUM THEME
Discontinues Galerkin Methods (DGM) have been developed only
recently but have found use quickly in such diverse applications
as aeroacoustics, semi-conductor device simulation, turbomachinery,
turbulent flows, materials processing, MHD and plasma simulations,
and image processing. While there has been a lot of interest in DGM,
only scattered information is available and there has been no prior
effort in organizing a conference and in publishing the existing
volume of knowledge on this subject. We invite participation of
mathematicians, physicists, and engineers working in this area
for possible contributions and plan to publish proceedings with
selective contribution to serve as a reference on the subject.

It is likely that several other speakers, who work closely with one
or other of the principal speakers, will present additional formal
or informal talks in association with them. Additional offers to speak
are welcome but it is the view of the organisers that it is not
appropriate to present the same lectures here as at SciCADE99, since many
participants will take part in both meetings. On the other hand, less
formal expositions of the same work would fit in well with the workshop
style of ANODE99.

so this message is to call for book proposals and manuscripts.
The books we will consider should be in one of the following groups:
upper level undergraduate, graduate level,research level.
We intend to publish texts,monographs,proceedings of conferences,
handbooks and compilations of papers.
The published books will be suitable for students, researchers, libraries
in Mathematical Sciences, Engineering,etc.
Interested potential authors should send 3 hard copies of their book
