**Subject: Possible NA Conference with STOC 97**

CONFERENCES BACK-TO-BACK WITH STOC'97: IS ANYONE INTERESTED?

We have been recently informed that El Paso was officially selected as a

site for 1997 ACM STOC (Symposium on Theory of Computing, May 4-7, chairman

of the local organizing committee Luc Longpre, longpre@cs.utep.edu).

STOC is the largest ACM symposium, that attracts lots of researchers

in all areas of theory. Several times, it has been organized

back-to-back with other ACM and other conferences that are

thematically similar. Having several conferences at one place enables

researchers and students to visit several at the time with a reduction

in total cost, and thus increases the attendance of all conferences.

Having several conferences at the same place also makes the job of

local organizers easier.

In view of that, I have the following proposal to NA community.

As the latest STOC conferences show (in particular, STOC'95 that

was held this May in Las Vegas), there is a growing interest in

theoretical aspects of computations with real numbers: algorithms,

computational complexity, different computational models.

Therefore, I think that it may be beneficial to organize

NA-oriented conference(s) and/or workshop(s) back-to-back with STOC.

STOC will be held in the hotel Camino Real Paso del Norte (the best

hotel in town). They give special rate of $60-80$ for the conferences.

As of now, they have space available unitl May 23, 1997, but the space

fills fast, so if anyone is interested, we need to act fast.

El Paso is right on the border with Mexico, and my experience of

organizing the International Workshop on Applications of Interval

Computations here in El Paso this February shows that this city and

especially its surrounding sites are a tourist attraction.

Due to my specific interests, one possibility would be to have another

Interval Computations conference; however, interval community may

prefer some yet unvisited site, so it may be possible to have a

broader (or somewhat different) meeting(s) instead.

I would greatly appreciate any suggestions and/or names of people who may be

interested.

Yours

Mathematics of Control, Signals, and Systems (MCSS)

CALL FOR PAPERS

Readers of this newsletter are encouraged to submit their work to MCSS.

The backlog that existed years ago has been completely cleared.

For instance, several papers that were received in the second half of

1994 are already appearing in the 1995 volume.

MCSS publishes one volume (four issues) per year, with about 400 pages.

AIMS AND SCOPE

MCSS publishes original and high-quality research papers concerned with

mathematically rigorous, system theoretic aspects of control and signal

processing.

HANDLING OF PAPERS

A paper is assigned to an Associate Editor, who makes a publication

recommendation on the basis of a detailed and careful evaluation by

two or more referees.

Evaluation criteria used include originality, substance, and quality

of exposition. To maintain the highest possible standards of quality,

and to pursue the goal of timely publication, only a small fraction of

submitted papers can be expected to be accepted. The journal strives

for a fast turnaround in the review process.

SUBMISSION

A typical paper submitted to MCSS consists of an average of 20 pages

of LaTeX in 12 point article style with a maximum of 25 such pages,

50 double-spaced typewritten pages, or the equivalent.

If a paper is longer than the maximum number of pages then authors

are requested to provide a justification for the added length in

their cover letter.

Associate Editors and reviewers are instructed to pay careful

attention to conciseness as an important characteristic of good

mathematical exposition.

The address for submissions is:

Authors wishing to inquire about the scope of the journal

or the suitability of a particular topic are encouraged

to contact the Editors informally, preferably by electronic mail,

prior to submission. Email inquires regarding submission should

be addressed to mcss@cwi.nl.

WWW PAGES OF MCSS

http://www.cwi.nl/cwi/departments/BS3/mcss.html

http://www.math.rutgers.edu/~sontag/mcss.html

These pages are identical; the access is faster to one of these

depending on the geographical area from which the request originates.

The MCSS Home Page provides general information on the

journal, as well as information regarding the submission

of manuscripts. Two additional pages can be accessed from

the main page:

- a page which provides information on the tables of

contents of recently appeared issues of MCSS and on

papers accepted for publication but not yet published;

- and a page which provides information on the tables of

contents of the older volumes of MCSS.

We look forward to your contributions!

**Subject: Rocky Mountain Numerical Analysis Conference**

Rocky Mountain Numerical Analysis and Applications Conference

RECALL ORIGINAL ANNOUNCEMENT:

The Rocky Mountain Numerical Analysis and Applications Annual

Conference will be held on the campus of the University of Utah in

Salt Lake City during the days of July 31 to August 2, 1995. The

object is to have an informal meeting of interested people to give

talks, discuss problems, share ideas and have a good and productive

time with colleagues. The presentations should be of about 30 minutes

in length, with the possibility of some longer talks. There will also

be two special workshops, one on Sinc functions and the other on

simulation of flow in porous media.

HOUSING

Kelly West, at Quality Inn, has set aside 15 rooms, for people to use,

checking in on or about July 30, and checking out on Aug. 2. I have

arranged with him that individuals should make their own reservations

with Quality Inn. The number of Quality Inn is (801) 521-2930.

Kelly's extension (not necessary for checking in) is #5396. When

people check in, they should simply state that they are participating

in the Numerical Analysis Conference that is being held at the

University of Utah, July 31 to Aug. 2.

LECTURES

The conference will be held in (either one or both) of the lecture

rooms EMCB 101 and EMCB 124, at the University of Utah. A schedule of

talks will be posted at the entrance of these lecture rooms, at 8:30

of July 31. If you are coming, please send a title and abstract of

your talk at your earliest convenience to one of us -- the organizers

of this meeting -- in order for us to be able to make up the schedule.

There is no registration fee for the conference.

ENTERTAINMENT

We will not have any talks on the afternoon of Aug. 1, to enable

participants to visit interesting sites in the vicinity of Salt Lake City.

FUNDING

As you probably are aware, due to the small size of the conference, we

have been unable to obtain outside funding. Hence everyone will have

to take care of their own lodging, meals, and travel.

**Subject: Multigrid Tutorial at Weizmann Institute**

MULTIGRID TUTORIAL, WITH APPLICATIONS TO

MOLECULAR DYNAMICS

October 10-12

Weizmann Institute of Science

Rehovot, Israel

Current molecular mechanics algorithms severely restrict the

modelling efforts to relatively small molecular systems and/or

tiny evolution intervals, since their computing cost rises very

steeply with problem size. Model studies have shown that this

steep rise can be substantially reduced by combining several types

of multiscale methods. These are multigrid-like methods, based

on designing a hierarchy of molecular motions on increasingly

larger scales, with several kinds of inter-scale interactions.

The course will teach the elements of the multigrid methods for

PDEs; algebraic multigrid (AMG), especially for non-PDE problems;

multi-scale Monte-Carlo techniques; fast multi-scale summation

of long-range forces; and global optimization by multi-level

annealing. First steps in introducing such methods to molecular

systems will be reported. Also, poster sessions on molecular

mechanics and dynamics will be given by some of the course

participants, exposing the audience to a large number of other

topics and ideas.

The course will assume an audience with a good working knowledge

of numerical methods and a strong interest in molecular mechanics

and dynamics simulations.

Registration fee is $50.00. The number of participants will be

limited. Some background reading material will be suggested and/or

sent upon request.

People interested in participating should contact the course

**Subject: Matrix Computations and QCD Workshop**

Workshop on Large Sparse Matrix Computations

and Lattice QCD Workshop

August 31 -- September 2, 1995

University of Kentucky, Lexington, Kentucky

The motivation for this workshop derives from the recognition that it is

important and timely to bring together numerical analysts and physicists

who work on large sparse matrices. Since physicists in lattice quantum

chromodynamics (QCD) in high energy physics are consuming a large fraction

of the world's supercomputer time and are building special purpose parallel

processors to meet the stringent numerical demands, better algorithms from

numerical analysts would be extremely helpful. On the other hand, problems

like those in lattice QCD provide challenge to numerical analysts. The

workshop will provide the need for this cross fertilization of ideas between

these two disciplines. Furthermore, since large sparse matrices are common

in other areas of physics, chemistry, and engineering, new ideas generated

in this workshop are likely to be beneficial to many fields.

The workshop is supported in part by Center for Computational Sciences

and Vice Chancellor of Research and Graduate Study, University of Kentucky

and Institute for Mathematics and its Applications, University of Minnesota
