**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.

**Subject: Auckland Workshop on Numerical Ordinary Differential Equations**

Second Auckland International Workshop on

Numerical Ordinary Differential Equations

(ANODE99 Workshop)

Following a succesful international workshop in July 1998

and several local workshops, the second international workshop

in the series is being planned for

16 - 20 AUGUST 1999

at

The University of Auckland

Auckland, New Zealand

Note that the timing fits in with the SciCADE99 Conference scheduled

for 9 - 13 August 1999 in Fraser Island, Queensland, Australia.

The following speakers have agreed to present extended lectures or

series of lectures

Ernst Hairer, University of Geneva

Linda Petzold, University of California at Santa Brabara

Marino Zennaro, University of Trieste

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.
