Subject: Backwards Error Analysis and Chaos
Members of the NA Net may be interested in the recent
article in SCIENCE (Sept. 2) entitled "Computer-drawn
pictures stalk the wild trajectory." It appears that
backwards error analysis is proving fruitful in the study
of strange attractors -- in particular, in proving that
computer-generated attractors are close to exact ones
despite the errors introduced by floating-point arithmetic.

Subject: Condition Number Estimator for Polynomial Roots Wanted
I would appreciate any and all pointers to publications on the
subject of a posteriori condition or accuracy estimators for
for numerically computed roots to polynomials.

Subject: Position at North Carolina State
POSITION IN SCIENTIFIC COMPUTATION
NORTH CAROLINA STATE UNIVERSITY
The Departments of Mathematics and Computer Science invite
applications for a junior level tenure track position in support of our
Center for Research in Scientific Computation. The position will be
joint between the two Departments, with the successful applicant
determining his/her major Department. Applicants working in parallel
processing and numerical linear algebra are of special interest to both
Departments. Applicants will be expected to have or to receive a Ph.D.
in Applied Mathematics or Computer Science before their Fall 1989
appointment. Applicants should have a strong interest in both research
and teaching. Immigration status of non-US citizens must be stated
in the application. Applicants should arrange to have 3 letters of
recommendation accompany their application. North Carolina State
University is an equal opportunity/affirmative action employer.
Submit resumes and arrange for 3 letters of reference to be sent to

The Center for Research in Scientific Computation(CRSC) was
established to serve the University of North Carolina System by the
Board of Governors in order to provide a focal point for research in
Computational Science and Engineering. Its mission is to coordinate
such research activities in the UNC System and particularly in the
Research Triangle Area of North Carolina. The CSRC is administered
by the Department of Mathematics in the College of Physical and
Mathematical Sciences and the Department of Computer Science
in the College of Engineering at North Carolina State University.

Subject: Errata for LAA Index
Errata for Volume 100 of "Linear Algebra and its
Applications":
Volume 100 of LAA was an index volume, which in particular
contains references to papers published in LAA since its
inception in 1968. As is to be expected with such a large
project, some errors have ocurred. We plan to prepare an
Errata and would appreciate hearing from anyone who has
discovered an error or omission.
