Subject: Phone Prefix Change for Argonne National Labs

The phone prefix for Argonne National Labs has changed from
972 to 252. So for example, my number is now (708) 252-8875
instead of the old (708) 972-8875. Some 972 numbers may still
work for a while, but may go away any day.

Subject: Proceedings of Bristol Conference on Dynamics

I wish to bring to the attention of the NA-net community the
publication of the proceedings of the Bristol Conference on "The
Dynamics of Numerics and the Numerics of Dynamics".

The publicity material says:

"The original conference was unique in bringing together specialists in
nonlinear dynamical systems and numerical mathematics. The papers
present a broad range of topics of interest to both research
communities -- applications of dynamical systems in numerical analysis
and of numerical problems and techniques in dynamical systems.

Although numerical analysis and nonlinear dynamical systems appear to
be incompatible, in fact both approaches to increasing our
mathematical understanding are mutually dependent. Numerical analysts
benefit from seeing the numerical algorithm itself as a dynamical
system, while numerical expertise is useful in elucidating the
behaviour of nonlinear systems."

The volume includes eleven invited talks and surveys by a range of
leading specialists from both communities:

R. Temam: General methods for approximating inertial manifolds.
Applications to computing.
J. Carr: Slowly varying solutions of a nonlinear partial differential
I.N. Stewart: Bifurcation theory old and new.
D.S. Broomhead: The geometry of dynamics.
J.M. Sanz-Serna: Numerical ordinary differential equations vs.
dynamical systems.
D.R. Moore & N.O. Weiss: Sensitivity of bifurcations to discretization.
H.B. Keller: A numerical approach to Hilbert's sixteenth problem.
R.S. Mackay: Some aspects of the dynamics and numerics of Hamiltonian
J.P. Keener: Uses and abuses of numerical methods in cardiology.
D.F. Griffiths & A.R. Mitchell: Spurious behaviour and nonlinear
instability in discretised partial differential equations.
J.K. Hale: Dynamics and numerics.

The book has been edited by Dave Broomhead and myself, and published
by Oxford University Press (ISBN 0-19-853642-9).

Fourth ACM-SIAM Annual Symposium on Discrete Algorithms (SODA)
Sponsored by ACM Special Interest Group on Automata and
Computability Theory, and SIAM Activity Group on Discrete Mathematics

January 25-27, 1993, Radisson Plaza Hotel, Austin, Texas

This symposium is for those interested in the use, design,
and analysis of algorithms, with special emphasis on
questions of efficiency. Papers about algorithms
(sequential, parallel, distributed, randomized, etc.) in all
areas of application are invited. Papers on the application
of advanced algorithmic techniques to real world problems
are especially solicited. Such papers will be judged on the
interest and novelty of application, and on the significance
of the practical lessons learned.

The call for papers and information on how to submit
extended abstracts will be available May 15, 1992. To
receive your copy, contact SIAM ... n o w !!
