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.

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 Robert J. Plemmons, Director Center for Research in Scientific Computation North Carolina State University Campus Box 8206 Raleigh, NC 27695-6206 email: rjp%ece-csc@ncsuvx.ncsu.edu 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. ------------------------------ From: Joe Flaherty Date: Thu, 15 Sep 88 10:44:03 EDT Subject: Workshop on Adaptive Methods for PDEs Workshop on Adaptive Methods for Partial Differential Equations October 13-15, 1988 Rensselaer Polytechnic Institute Troy, New York Sponsored by the U.S. Army Research Office A workshop emphasizing new ideas and innovations in adaptive numerical methods for solving partial differential equations.
