**Subject: Golub Establishes Award at Urbana**

Barbara Morris and Gene Golub were guests of the University of Illinois

Urbana-Champaign on Monday and Tuesday of this week. Gene gave a talk on

Tuesday afternoon, March 3, on ``Scientific Computation and Cyclic

Reduction.'' That evening, he presented awards at a banquet to the first

recipients of the Hohn-Nash awards. Gene established the award in 1997 to

honor Professors Franz Hohn and John Purcell Nash, members of the faculty

when Gene was a student in Urbana.

**Subject: Mathieu and Spheroidal Wave Functions**

I am looking for Fortran routines

to generate Mathieu and Prolate Spheriodal Wave Functions

which arise when solving the wave/helmholtz equation in

elliptical and spheroidal coordinates respectively.

The separation of the scalar Helmholtz equation in

elliptical/spheroidal coordinates

results in mathieu/spheroidal wave functions.

I would be very grateful to get information about

any existing FORTRAN routines for evaluating the Mathieu "radial" & "angle"

functions and prolate spheroidal "radial" & "angle" functions.

**Subject: Polynomials with Random Coefficients**

Can anyone help with the following problem in the area of random matrices?

We have r_i uniformly distributed in [-1,1] and compute from it the values

d_i = r_i-2r_{i-1}+r_{i-2} which are then `bell-shaped' distributed:

\phi(d) = x^2/32 + x/4 + 1/2 -4 <= x <= -2

-x^2/32 + 1/4 -2 <= x <= 2

x^2/32 - x/4 + 1/2 2 <= x <= 4

We want to study the monic polynomial

| 1 ... z^{n-1}|

| d_{2n-1} ... d_n |

D_{n-1}(z) = | ... | / (coefficient of z^{n-1})

| ... |

| d_{n+1} ... d_2 |

Numerical evidence suggests that the coefficients in the above polynomial

follow a Gaussian-like distribution with mean value 1, in other words that

statistically the polynomials D_{n-1}(z) and 1+...+z^{n-1} are `close'.

Is anything more specific known? We also expect the variance to get smaller

as n becomes larger.

Thanks a lot in advance.

**Subject: Approximation of Polynomial-exponential Expression**

Dear colleagues!

I have a function

%

$$

p(B,Z|b,z,n,m) \propto B^b e^{-nB} (B+Z)^z e^{-m(B+Z)}.

$$

I would like to

1) integrate it over $B$ and use it as univariate function of $Z$,

2) multiply it by $Z^k$, where $k=0,1,2$ and integrate over $B$ and $Z$.

I am searching for suitable approximation that would lead to 'easy'

evaluation (without polynomes of degree $z$ and high factorials; powers

of $z$ and exponentials are acceptable) in both the cases 1) and 2). The

considered magnitudes are:

-- $m$, $n$ are constant integer numbers of magnitude 10 -- 100,

-- $b$ is constant integer of order $10^2$,

-- a) $z$ is constant integer of the same order as $b$ or

b) $z$ is constant integer of order $10^4$ and higher

-- in case 1) the value of variable $Z$ can be arbitrary non-negative.

There can be also several approximations and each of them would cover some

particular case mentioned above. I will be grateful for any tip or advice.

What is it?

It is Bayesian solution of radioactive source intensity $Z$ estimate on a

radiation background $B$. The function mentioned above is non-normalized

probability density function of $B$ and $Z$.

-- $b$ is total count of particles coming from the background during $n$

seconds; for each second the counts are Poisson distributed with

mean value $B$,

-- $z$ is total count of particles coming from both the source and the

background during $m$ seconds; for each second the counts are

Poisson distributed with mean value $B+Z$.

The aim is to find first two moments of $p(Z|...)$ and/or desired

credibility interval of $Z$ occurence.

**Subject: Parallel Linear Algebra Package General Solver Available**

Parallel Linear Algebra Package General Solver Available

During the last two years the PLAPACK project at UT-Austin has

developed an MPI based Parallel Linear Algebra Package (PLAPACK)

designed to provide a user friendly infrastructure for building

parallel dense linear algebra libraries. Now that this infrastructure

has stabilized, we have started developing libraries. The first

solver available, PLA_Gesv, solves general linear systems.

PLAPACK provides a high level abstraction for coding dense linear

algebra algorithms. It is often believed that such a high level

abstraction comes at the price of lower performance. We are happy to

report that while this is temporarily true for smaller problem sizes

(where the fact that we have not yet optimized the infrastructure is

still noticeable), the higher level of abstraction allows for more

sophisticated algorithms to be implemented, which attain higher

performance for larger problem sizes.

The following performance comparison between PLAPACK and the

equivalent ScaLAPACK routine on a 16 node Cray T3E-600

(300 Mhz) demonstrates this:

Performance of dense linear solve

2000 66 101

5000 174 168

7500 228 201

10000 268 209

The ScaLAPACK performance numbers were derived from those reported in

the ScaLAPACK Users' Guide. We conducted our own experiments on the

T3E used to collect the PLAPACK numbers and found the ScaLAPACK

numbers to be representative.

GAMM-WORKSHOP on Iterative Processes for Solving Equations

Mathematisches Seminar,

July 3rd to 5th, 1998

Organizers:

C. Carstensen (Kiel)

P. Kosmol (Kiel)

M.S. Petkovic (Nis, Yugoslavia)

The aim of this Symposium is to bring together mathematicians

working in all fields of iterative processes with the aim of

approximating the zeros of singles or systems of equations.

The nature and origin of the equations is understood in a

broad sense ranging from classical topics as the simultaneous

computing of all the zeros of an algebraic polynomial to the

sparse non-linear systems as they, for instance, arise in a

finite element discretization of non-linear partial

differential equations or optimization problems. Linear

iterative solvers for high-dimensional systems belong to the

scope of the symposium on its own or with emphasise as part

of a non-linear problem. The subtile problem of finding

initial conditions for a local solution is of interest as

well as computable sufficient conditions for convergence or

general local higher order methods.

Topics of interest include, but are not restricted to, the following:

o Optimization

o Control theory

o Calculus of variation

o Plasticity

o Partial differential equations

o Contact

o Microstructures

Everybody interested in the topics of the symposium is warmly

invited to attend. Please let us know about your intention to

participate by April 15, 1998. A second announcement with

further information, in particular, concerning hotel

accommodation, will be distributed in April 1998.

Call for papers: Participants wanting to give a talk (20 min)

should submit an abstract before April 15, 1998.

Notification of acceptance will be given on April 30, 1998.

List of invited speakers includes:

O. Axelsson (Nijmegen), M. Dryja (Warsaw), B. Fischer (Luebeck),

**Subject: Research Position at Johannes Kepler Universitaet, Linz **

Position in Linz

We will soon have an industry-funded 3-year position (renewable after

each year) at the Johannes Kepler Universitaet Linz for a project

with a large car company involving collision problems with tolerances;

this is art of a long term cooperation, where we will be dealing with

inverse problems of the type "How do certain tolerances in a CAD-construction

have to be chosen in order to guarantee that the final part meets certain

criteria (under all admissible tolerance situations) like, in a given

motion, hitting or not hitting another part (again with tolerances)."

I am looking for a mathematician with high computer-literacy, experience

in object oriented programming, good geometric intuition and knowledge

of optimization methods. Diploma or equivalent and EU citizenship

required. Possibility of using the work to be done for a doctoral thesis.

Salary around 380.000 Austrian Schilling before tax.
