Subject: Travel Support for ICIAM 95

SIAM is administering a travel grant program for ICIAM 95 --
the third International Congress on Industrial and Applied
Mathematics -- to be held in Hamburg, Germany, July 3-7. The grants,
which are funded by the National Science Foundation and the
Department of Energy, will provide partial travel support to
qualified applicants.

The awards are intended primarily for young researchers and graduate
students; women and minorities are especially encouraged to apply.
APPLICANTS MUST BE AFFILIATED WITH U.S. INSTITUTIONS. Awards will be
based on merit. Preference will be given to participants in the ICIAM
95 program and to applicants who do not have other travel support for
the meeting.

Typical anticipated awards will range from $800 to$1000. Travel
costs will be reimbursed up to the amount of the award on submission
of a signed travel expense from to SIAM.

The cutoff date for applications is March 15, and final decisions
will be made no later than April 15. Early submission of
applications is encouraged; whenever possible, SIAM will make
decisions and notify applicants as the applications are received.

[Editor's Note: Ordinarily, we don't include forms like this in the
NA Digest. I'm making an exception because it's a meeting of broad
interest to NA Net and because the application deadline is very near.
The form requires a signature, so it can't be e-mailed. -- Cleve]

Subject: Hyperbolic PDE Solver Wanted

Numerical PDE Solver Wanted

I am looking for a higher-order numerical solver to handle
simple linear hyperbolic differential equations (ideally, a
solver which is 4th order in both space and time). In particular,
I would like to get hold of code that can handle both the first and
second order wave equation, both on a periodic domain, and on
an infinite domain with radiating boundary conditions.
(Even code that can handle one of these 4 cases would be a good start.)

I believe an implementation of a spectral method would be
well suited to these problems (with RK4 in time, eg.).
My sense is that this would be preferable to a 4th order finite
difference in space scheme, as there could be problems
with the boundary conditions. I am looking at all options, however.

Thank you in advance for all possible leads.

Request for Donations for a Memorial Dedicated to G\'abor Szeg\H{o}

Dear Friends:

F.Y.I. G\'abor Szeg\H{o} was born one hundred years ago on January 20, 1895,
in Kunhegyes, Hungary.

This is to solicit your generous donations for some type of a memorial (most
likely a bronze relief to be set up in Kunhegyes in front of the city
library) dedicated to G\'abor Szeg\H{o}. I understand that such a memorial
will cost in the neighborhood of three to five thousand US dollars.

Please send me whatever you can afford, say, $10 or$25 or $100 or more (perhaps in cash but preferably by checks payable to Paul Nevai, Dept Math - OSU, Columbus, Ohio 43210-1174, U.S.A.) and I will make sure that all the money collected will be used for that purpose. If you send me$25 or more, you will get a photograph of this memorial signed
by a selected mathematician such as Dick Askey or Paul Erd\H{o}s or Samuel
Karlin or Peter Lax or Lee Lorch or Gilbert Strang or Harold Widom or one of
the children of G\'abor Szeg\H{o}.

Depending on the money collected, I promise to add a substantial amount from
my own resources. My final goal is in the neighborhood of 5K.

Sincerely,
Paul Nevai

P.S. This message has been endorsed by Professors Dick Askey, Paul Erd\H{o}s,
Samuel Karlin, Peter Lax, Lee Lorch, Gilbert Strang, and Harold Widom.

P.P.S. Please send copies of this message to your colleagues and friends all

Subject: Postdoctoral Positions at Argonne National Laboratory

Postdoctoral Positions
Mathematics and Computer Science Division
Argonne National Laboratory

Argonne National Laboratory invites candidates to apply for two
postdoctoral research positions in the Mathematics and Computer
Science Division.

Selected candidates will work with a team that includes Bill
Gropp and Barry Smith developing application driven algorithms and
software for the parallel solution of large-scale systems of nonlinear
equations arising from the discretization of coupled systems of
PDEs. The software developed will be built on the framework of
the PETSc (http://www.mcs.anl.gov/petsc/petsc.html) package.

Candidates are sought in either of the following two research areas:

1) to help with the design and implementation of algorithms and
data structures for the direct and iterative solution of sparse
linear systems. The focus will be on methods that can achieve high
performance on hierarchical-memory machines including RISC workstations
and distributed-memory machines such as the IBM SP2.

2) with interest and experience in distributed memory parallel
computing for numerical linear algebra and/or partial differential
equations, possibly including domain decomposition and/or multilevel
methods. Candidates would work on the design, analysis and
implementation of parallel solver methods and related issues.

Applicants must have received their Ph.D. in computer science,
applied mathematics or a related discipline not more than three
years prior to the beginning of the appointment. The appointment
is available immediately for a one-year term (renewable).
Applications should be addressed to Walter McFall, Box mcs-acti3,
Employment and Placement, Argonne National Laboratory, 9700 S.
Cass Avenue, Argonne, IL 60439, and must include a resume' and
the names and addresses of three references. For additional
information, contact Barry Smith (bsmith@mcs.anl.gov).

The Mathematics and Computer Science Division supports an
excellent computational environment that includes access to
high-performance scientific workstations, a scientific visualization
and virtually reality laboratory, and state-of-the-art parallel
computers (including a 128-node IBM SP).

Argonne is located in the southwestern Chicago suburbs, offering
the advantages of affordable housing, good schools, and easy access
to the cultural attractions of the city.

Argonne is an affirmative action/equal opportunity employer.
