Is anyone aware of a similar digest to NAD that focusses on

computational number theory?

**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.

for the publication of significant new and important developments in numerical

analysis and scientific computing. In addition to the rapid publication of

scholarly work, ETNA now permits the publication of manuscripts containing

COLOR figures, diagrams, or photographs.

An individual who wishes to obtain a copy of a current or back manuscript can

get a copy through World Wide Web (URL http://etna.mcs.kent.edu) browser such

as Mosaic or Lynx. ETNA is also available through Gopher (etna.mcs.kent.edu),

anonymous ftp (etna.mcs.kent.edu), or through e-mail (send e-mail to

mailer@etna.mcs.kent.edu containing the phrase: send index).

To register to receive ETNA's quarterly list of titles and abstracts, please

send an e-mail message to etna@mcs.kent.edu. The subject of the message

should be: ETNA registration. Titles and abstracts of papers published in

ETNA will be e-mailed quarterly to the return addresses of all such requests.

Inquiries for further information should be e-mailed to etna@mcs.kent.edu.

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).
