Subject: 1995 Copper Mountain Multigrid Conference Preprints

Once again, the proceedings will be published by NASA.  As last time, the
pre-proceedings will be available electronically through MGNet before the
conference.  Thus, you will not receive a tree trunk to take home.  In fact,
you can bring it on your laptop and preview the papers with ghostview, mosaic,
or your favorite web browser.

The directions on how to submit something to MGNet are kept in the file
mgnet/How2Submit.mgnet (you can find this information using a web browser,
too).  Basically, all you need to do is the following:

                                   * * * *

Thank you for submitting a paper to the 1995 Copper Mountain Conference on
Multigrid Methods.  This year, we are going to continue the tradition of
putting the papers on MGNet [1].  NASA will be putting the informal
proceedings out as a report at some point.

In the meantime, the organizers would appreciate it if you would put your
paper in the MGNet repository.  This way, anyone can see what you plan on
talking about before coming to Copper Mountain.

There are 3 methods for getting your paper to MGNet.  They are, in order of
preference,

    1. Download the paper using ftp on the Internet.
    2. E-mail the source (some flavor of TeX or whatever)
    3. Mail me a 3.5 inch DOS formatted floppy.

The papers will be in the directory mgnet/Conferences/CopperMtn95 on the
machine casper.cs.yale.edu (Internet machine 128.36.12.1).  See the README
file in that directory for more information.  This repository is mirrored at
ftp.cerfacs.fr (Internet machine 138.63.200.33), but does not have a world
writable directory.

Hopefully, this will all work.  Please have a little patience if things seem
to be going awry.  If all else fails, call me or send e-mail.

Regards,
Craig Douglas

                   DIRECTIONS for Putting a Paper on MGNet

1. Instructions for downloading papers to MGNet:

        % ftp casper.cs.yale.edu        => Begin (or ftp 128.36.12.1)
        User: anonymous                 => You type anonymous
        Password: dinner@nine.pm.est    => You type your e-mail address
        ftp> cd mgnet/incoming          => Change to the incoming directory
        ftp> mkdir your_name            => Make a directory for yourself
        ftp> cd your_name               => Change to your directory
        ftp> put paper.abs              => Put an abstract file (ascii, please)
        ftp> binary                     => Binary transfer
        ftp> put paper.ps               => Put the paper in some format
        ftp> quit                       => All done

The abstract file should be the same one that you submitted in December, 1994.
The paper.dvi file above can also be paper.tex or whatever.  If you include a
TeX file, please put a comment line at the top with directions on how to make
the file (at least, please indicate which flavor of TeX you used -- LaTeX,
AMSTeX, Plain TeX, etc.).

PostScript files are preferred, but .dvi is also fine.  If your paper includes
PostScript figures in separate files, please download those as well (or
indicate that you did not do this).

Then mail mgnet-requests@casper.cs.yale.edu a message saying you downloaded a
paper for the Copper Mountain meeting.  I will send you an acknowledgment as
soon as possible.

2.  Just e-mail your paper and abstract files to

        mgnet-requests@casper.cs.yale.edu

Include on the subject line that this is a Copper Mountain paper.

It will help greatly if you do not have any lines longer than 80 characters
(certainly not longer than 128).  This is because certain machines (e.g., IBM
mainframes) have the habit of trimming long lines in mail.  I will try to
determine that your files arrived intact.  In any case, I will send you a note
with a success or failure indication.

3.  If all else fails, I will also accept 3.5 inch floppies formatted under
DOS.  Make certain you label your floppy with your name.  If you want me to
send you an acknowledgment, please include a return address (e-mail
preferred).

Mail your floppy to me at my home address:

    Dr. Craig Douglas
    8 South Street
    Cos Cob, CT 06807-1618
    USA

This will get to me quicker than if you send it to my office (further, I
will even get it this way).

                  DIRECTIONS for Retrieving a Paper on MGNet

* Scientific background

  The nature of the interactions between different scales of
phenomena in a complex system has recently become the focus of
interest in an increasingly wider range of scientific fields.
This interest originated independently in theoretical physics
and in computational mathematics.

  The purpose of the Eilat workshop is to bring together different
communities of researchers interested in the methodology, derivation,
exploitation, and philosophical implications of multiscale interactions.

  The participants include theoretical physicists and computational
mathematicians. The physicists are mainly from the field theory and
statistical mechanics communities, especially in the theoretical and/or
simulation aspects of renormalization group, criticality and universality.
Many of them manifested lately a growing interest in the more general
theory of dynamical and complex phenomena and/or in their computational
aspects. The participating mathematicians will represent several research
communities which have adopted different versions of multiscale scientific
computation: multigrid, multipole, hierarchical bases, wavelets, and other
relatives.

                                   ABSTRACT

The purpose of this paper is to establish an equivalence between mixed and
nonconforming finite element methods for second order elliptic problems on
both triangular and rectangular finite elements, and to provide an analysis of
multigrid methods for both methods based on the equivalence.  We first show
that the linear system arising from the mixed method can be algebraically
condensed to a symmetric and positive definite system for Lagrange multipliers
using features of mixed finite element spaces and that the system for the
Lagrange multipliers is identical to the system arising from the nonconforming
method.  Then we prove that optimal order multigrid algorithms can be
developed for both methods.  Two types of multigrid methods are considered in
this paper.  The first one makes use of the coarse-grid correction on
nonconforming finite element spaces, while the second one has the coarse-grid
correction step established on conforming finite element spaces.
Finally, numerical examples are given to
illustrate the present theory.

                                   ABSTRACT

In this paper domain decomposition algorithms for mixed finite element methods
for linear and quasilinear second order elliptic problems are developed.  A
convergence theory for two-level and multilevel Schwarz methods applied to the
algorithms under consideration is given, and its extension to other
substructuring methods such as vertex space and balancing domain decomposition
methods is considered.  It is shown that the condition number of these
iterative methods is bounded uniformly from above in the same manner as in the
theory of domain decomposition methods for conforming and nonconforming finite
element methods for the same differential problems.  Numerical experiments are
presented to illustrate the present techniques.

                                   ABSTRACT

A new approach of constructing algebraic multilevel preconditioners for mixed
finite element methods for second order elliptic problems with tensor
coefficients on general geometry is proposed.  The linear system arising from
the mixed methods is first algebraically condensed to a symmetric, positive
definite system for Lagrange multipliers, which corresponds to a linear system
generated by standard nonconforming finite element methods.  Algebraic
multilevel preconditioners are then constructed for this system based on a
triangulation of parallelepipeds into tetrahedral substructures.  Explicit
estimates of condition numbers and simple computational schemes are
established for the constructed preconditioners.  Finally, numerical results
for the mixed finite element methods are presented to illustrate the present
theory.

Subject: Travel Support Available for ICIAM 95

SIAM is administering a travel grant program for ICIAM 95 to be held in
Hamburg, Germany, July 3--7.  The grants, which are funded by the National
Science Foundation and the Department of Energy, will provide partial travel
support to qualified applicants.  Typical anticipated awards will range from
$800 to $1000.  Travel costs will be reimbursed up to the amount of the award
on submission of a signed travel expense form to SIAM.

The awards are intended primarily for young researchers and graduate students;
women and minorities are especially encouraged to apply.  Awards will be based
on merit.  Preference will be given to participants in the ICIAM 95 program
and to applicants who do not have other travel support for the meeting.

Additional information and application forms can be accessed through the SIAM
home page on the World Wide Web (http://www.siam.org) or the SIAM gopher
server (gopher.siam.org).  Application materials can also be obtained from the
SIAM office (ICIAM 95 Coordinator, SIAM, 3600 University City Science Center,
Philadelphia, PA 19104-2688; 215-382-9800; 215-386-7999 (fax);
meetings@siam.org).  The cutoff date for applications is March 15, and final
decisions will be made no later than April 15.  Early submission of
applications is encouraged; whenever possible, SIAM will make decisions and
notify applicants as the applications are received.

    Editor's Note: I usually do not run this type of submission since it is
    -------------  also run in the NA Digest.  Also, the vast majority of
                   MGNet members do not qualify for a variety of reasons.  If
                   you feel strongly that I should or should not not include
                   this type of message in MGNet, please send me e-mail at
