Subject: Tables of Contents Available on the Internet
I have collected the tables of contents from several numerical analysis
journals and made them available on the Internet. Presently the
following journals are available:
o SIAM Journal of Numerical Analysis, all issues since 1990 (vol. 27)
o Advances in Computational Mathematics, all issues since inception
o Numerical Algorithms, all issues since inception
Access to the files is available in three ways:
1) Via the World-Wide Web. Use a WWW browser (e.g., Mosaic) to
open the URL http://www.math.psu.edu/dna/, and then select
the journal you desire.
2) Via anonymous ftp. Ftp to the host ftp.math.psu.edu and log
in as user "anonymous" with your email address as password.
Then give the commands "cd pub/dna" and "get sinum.txt" or "get
aicm.txt" or or "get na.txt".
3) Via Gopher. Point your gopher client to gopher.math.psu.edu
and select in turn "Information and Personal Directories Available
from Mathnet", "Douglas N. Arnold <dna>", and then the journal you
want.
The World-Wide Web access is preferred if it is available to you since
it is the simplest to use, and will eventually have searching
capabilities that are not practical with the other access methods.
In the meantime, most WWW browsers have built-in string searching.
For example, with Mosaic this is available via "Find In Current..."
under the File menu.
I would be happy to extend this collection to more numerical analysis
journals. If you are involved in the editing or production of
a numerical analysis journal which you would like to see included,
please contact me.

Continuous algorithms and complexity
J. F. Traub (Columbia University), co-chair
J. Renegar (Cornell University), co-chair
Continuous computational complexity studies the complexity of contin-
uous mathematical problems. The motivation is that most problems in the
physical, biological, and social sciences, and even in finance, have contin-
uous models.
The mathematical problems that arise in this modeling include integral
equations, multivariate integration, optimization, ordinary differential
equations,partial differential equations, and systems of polynomial equations.
Continuous computational complexity is applied in many disciplines
including scientific computation, control theory, and statistics. Invited
speakers will cover the foundations of continuous computational complexity,
recent results, open problems, and applications.
Continuous computational complexity may be contrasted with discrete
computational complexity, that is, the study of the complexity of problems
such as scheduling and networking. Much of the research in theoretical
computer science over the past twenty-five years has been devoted to discrete
complexity.
Continuous computational complexity is a particularly good area for
researchers in the mathematical sciences. There is intense international
research activity. There are numerous important open problems which, while
deep, are solvable. Furthermore, progress requires mathematical tools such
as algebra, algebraic geometry, functional analysis, analysis in the large,
and measure theory.
Particularly promising new areas of computational complexity include:
Theoretical topics: Average case analysis of nonlinear problems, average
case complexity, complexity of multidimensional problems, relations between
condition numbers and complexity theory, models of parallel computation,
noisy data, power and limitations of randomization, and structural computa-
tional complexity.
Applications: Approximation, computer vision, dynamical systems, control
theory, ill-posed problems, integral equations, multivariate integration,
nonlinear equations, nonlinear optimization, ordinary differential equations,
partial differential equations, prediction and estimation, signal processing,
singularity detection, zeros of systems of polynomials, and systems of
polynomial equations and inequalities.
Members of the Organizing Committee: Lenore Blum (Mathematical
Sciences Research Institute and ICSI) and Henryk Wozniakowski (University
of Warsaw and Columbia University).
