Subject: Looking for Spherical Bessel Function Evaluator
We are looking for an evaluator for the Spherical Bessel
functions of the first kind (aka half-order Bessel functions).
This could be either be in the form of computer code(s)
or pointers to a continued fraction approximation to the SBF.
We know that we can obtain the SBFs from a standard
"J sub(N+ALPHA) (X)" evaluator, and we have previously used
Cody's RJBESL function from netlib, with good results. We also
have looked at the series approximation in Abramowitz & Stegun.
The problem that we are currently faced with is having to do
"a bit of algebra" when evaluating the kernel of an integral equation
in the vicinity of a singularity. An alternative approximation series
might help us do the math.

Subject: Generalized Eigenvalues, Maximum Real Part
Dear Colleagues,
We are looking for algorithms for the generalized eigenvalue problem
Ax = cBx
which find the maximum of Re(c) (the real part), where c ranges through the
set of generalized eigenvalues. In our application the matrices A and B
are large, complex, and square, but not necessarily Hermitian. It is not
feasible for us to compute all of the generalized eigenvalues. Your
suggestions for or directions to such algorithms would be greatly appreciated.
(We are aware of a method employing matrix exponentials and a power
iteration.)
Please direct responses to vivek@tam.cornell.edu .

Subject: Director Position at GSF, Bavaria
The GSF is a non-profit research centre funded by the Federal Government of
Germany and the State of Bavaria with approximately 1700 employees. Research
is focused on activities related to the protection of man and his environment
from harmful effects resulting from radiation or chemicals, and using
scientific and technical knowledge to improve the provision of health care.
We hope to fill the position of the
Direktor/in
des GSF-Instituts fuer Biometrie
as soon as possible.
The nomination will be jointly carried out in co-operation with the faculty of
mathematics of the Technical University of Munich. The director of the newly
founded Institut fuer Biometrie will also hold the chair (C4) of Angewandte
Mathematik in Oekologie und Medizin at the Technical University of Munich.
Please take notice of the announcement in the Deutsche Universitaetszeitung.
The applicant is expected to introduce new mathematical results and methods
into the disciplines of Medicine, Biology and Ecology. The institute,
with 14 permanent staff members, has the task of developing mathematical
methods modelling biological, ecological and medical processes, structures
and mechanisms on a co-operative basis. This includes for example the three-
dimensional modelling of the different environmental compartments as well
as developing simulation models for various ecological, medical and biological
problems.
Applicants should have excellent scientific qualifications and proven
management capabilities. He/she should be interested in internal and external
co-operation, both on a national and an international level. Salary level
corresponds to that of a full university professorship (C4). Applications
with curriculum vitae, list of publications, references and certificates
should be sent no later than April 30, 1995, to the scientific director
of the GSF:
