Title:         Multigrid preconditioning in H(div) on non-convex polygons
 
Authors:       Douglas N. Arnold, Richard S. Falk, and Ragnar Winther
 
Source:        Computational and Applied Mathematics
 
Status:        Submitted
 
Abstract:  In an earlier paper we constructed and analyzed a multigrid
preconditioner for the system of linear algebraic equations arising from
the finite element discretization of boundary value problems associated
to the differential operator I - grad div.  In this paper we analyze the
procedure without assuming that the underlying domain is convex and show
that, also in this case, the preconditioner is spectrally equivalent to
the inverse of the discrete operator.
 
Keywords: preconditioner, finite element, multigrid, nonconvex domain

Subject: Multigrid Paper

         Parallel Multigrid with ADI-like Smoothers in Two Dimensions

                  Craig C. Douglas (University of Kentucky)
              Sachit Malhotra (Scientific Computing Associates)
                     Martin H. Schultz (Yale University)

                                   Abstract

Alternating direction iterative (ADI) methods do not usually work well on
parallel computers due to having to do parallel rather than serial tridiagonal
solves in all but one dimension.  An ADI-like iteration is developed and
analyzed which does not require parallel tridiagonal solves in any direction,
has at least as good of a convergence rate as ADI, and has almost no
communication when imbedded as a smoother inside of a multigrid solver.
Numerical experiments on a network of workstations and a parallel computer are
included.

Subject: Deadline Change: DNS/LES Conference

                  FIRST AFOSR INTERNATIONAL CONFERENCE ON
        DIRECT NUMERICAL SIMULATION AND LARGE EDDY SIMULATION (DNS/LES)
                         August 4-8, 1997

I have received responses from more than 90 people from 16 countries who are 
interested in attending the FAICDL conference . Around 60 abstracts have been 
received so far.

Due to a number of requests by phone and email, we decide to change the 
deadline for submission of abstract to March 15th to give potential authors 
more time to prepare their abstracts. All other time schedules will be kept 
unchanged.

Subject: 8th Copper Mountain Conference on MG Methods, April 6-11

The schedule for the Eighth Copper Mountain Conference on Multigrid Methods
(April 6-11) is now accessible from the conference home page:

   http://amath-www.colorado.edu:80/appm/faculty/copper/

Anyone interested in attending should reserve their room as soon as possible.
This has been one of Copper's best ski seasons, so rooms are becoming more
difficult to find. Anyone interested in sharing rooms or condos might want to
use the bulletin board accessible from the conference home page.

                            Preliminary Program

          This program is preliminary and subject to modifications.
 Talks will generally not be moved from the given day, but the times may be
                          adjusted within that day.
    Participants and speakers should therefore monitor this page and the
                     bulletin board at the conference.
         Speakers should plan their talks to be at most 20 minutes.
           Program Chairs will adhere strictly to this schedule.

 We will have a slide projector and an overhead projector for speaker use.
  We will also provide an LCD panel (ViewFrame Spectra), which plugs into
a standard video outlet on a Mac or PC to project its image onto the screen.

This equipment will also be available for the Circus and Workshop sessions.

    Wednesday night's cash bar and banquet will be held in the Pavillon.
    All other activities will take place in the Village Square conference
                                facilities.
