Subject: Department Head at Clemson
MATHEMATICAL SCIENCES DEPARTMENT
Applications and nominations are invited for the position of
Department Head. Qualifications include a Ph.D. degree,
teaching experience, proven research ability, and leadership
capacity. Administrative experience is highly desirable but
not required. The Mathematical Sciences Department has 46
faculty members and over 100 graduate students. It offers a
broad program in the mathematical sciences including B.A.,
B.S., M.S., and Ph.D. degree programs for its majors;
provides service courses for students in science,
engineering, and education curricula; and jointly administers
a Ph.D. program in Management Science with the Management
Clemson's Department of Mathematical Sciences has pioneered
the concept of integrating major areas of the mathematical
sciences - algebra/combinatorics, analysis, computational
mathematics, operations research, and probability/statistics
- into balanced educational programs at both the
undergraduate and graduate levels. A candidate is sought who
is committed to working with the faculty to foster these
programs and who will provide leadership for the future
development of the Department.
Initial screening of applicants will begin in early March
1988 but applications will be accepted until March 28, 1988.
The position will be available August 1, 1988. Salary will
be commensurate with credentials and experience. Vitae (with
names and telephone numbers of three references who will be
contacted after the initial screening of applicants),
nominations, and requests for further information should be

Subject: Large eigenvalue problems
Does anyone know the answer to the following question? I need to efficiently
find the largest real eigenvalue of large (1000x1000) real, but not symmetric,
matricies. The matricies will in general have both real and complex
eigenvalues, but I'm only interested in the real ones. I need the value to
only a few percent. Is there any way to do this more efficiently than
finding *all* of the eigenvalues using a canned routine? Please reply to
ZOCKUS@FNAL on BITNET or FNAL::ZOCKUS on DECNET.

A NOTICE FROM JOHN GREENSTADT, WHO IS LOOKING FOR A JOB BACK IN THE STATES.
After 33 years, I left IBM at the end of 1985 to be able to concentrate
on developing my Cell Discretization algorithm. Thanks to Mike Powell, I
have spent the last two years as a Research Fellow at Cambridge University
in the Department of Applied Mathematics and Theoretical Physics (DAMTP).
I am expecting to return to the US at the end of July 1988.
Some of you know me on the basis of my past work on matrix eigenvalues
and various areas of optimization, but I have concentrated almost all my
efforts in recent years on the development of Cell Discretization (CD),
which is a generalization of the Finite Element Method. During my stay
here at Cambridge, I have been able to complete the formulation of the
the CD algorithm to cover nonselfadjoint systems of elliptic partial
differential equations, and I have drastically restructured my
Fortran program so that it can handle these cases. My preliminary
results on a few model boundary-layer problems are quite encouraging.
I plan next to incorporate a simple adaptive quadrature into my
program, so that I can handle special nonpolynomial representations
with my program. This should enable me to handle re-entrant corners
(including cracks) and steep fronts, for example, without the use
of very fine domain partitioning (refined grids).
By the use of a special range-space/null-space transformation, the
discretization process of CD decouples almost completely into a set of
independent cell-by-cell computations, eminently suited to parallel
processing. The key paper describing the basic procedure for selfadjoint
equations is in: SIAM Journal on Scientific and Staistical Computing,
vol. 3, pp 261-288 (1982).
I am quite happy with the way things are turning out, and would like to
find a spot in a university or a national laboratory where there is
interestin developing a new method of this sort. I would naturally
be very happy to teach students this method, and I am keenly aware that
there are very many problems still to be tackled in connection with CD,
most of which would be suitable for dissertations.
I would prefer to be located in Northern California, where my
present home is, but I would certainly consider seriously any position
which would offer me the chance to develop and teach the cell method.
If anyone has a position of this kind available, or knows of one, I
would be very glad to hear from him/her. I would also be very happy to
send a curriculum vitae and a few of my best papers to anyone who
thinks he/she might have a possible position available in the fall.
