Craig,

Updated this in http://info.desy.de/user/projects/MG.html
and related documents. 
Have you ever announced  this URL in the MGnet Digest?
It's active :)

    Editor's Note:  This was held at a castle southwest of Magdeburg in the
    -------------   mountains.  The conference surroundings were rather
                    nice, which made it easier to hold lengthy discussions.
                    Getting there was part of the adventure.  There were many
                    quite good talks, which are listed in part 2 below.

Subject: DDM7 preface and participant list

Craig,

As of notification received yesterday, AMS has approved the publication
of the DDM7 proceedings in the Contemporary Mathematics series, with an
estimated shipping date of January, 1995.

To celebrate, so to speak, I have placed the preface and the participant
list, which will appear as frontmatter in the proceedings, in the
mgnet incoming directory.  According as you see fit, you may place
them in the DDM7 subdirectory.

Recall that, under the agreement reached with AMS last fall, all of the
files in the DDM7 directory will have to be deleted when the book 
becomes available.

Thanks.

/David

UNIVERSITY OF COLORADO-BOULDER
APPLIED MATHEMATICS
GRADUATE TRAINEESHIPS

The Program in Applied Mathematics invites applications for National Science
Foundation Graduate Research Traineeships (GRTs).  The GRTs provide financial
support during a student's Ph.D.  study, including tuition for up to 5 years.
Two traineeships will be available for the academic year beginning fall, 1995.
Traineeships are available for US citizens only.  Several Graduate Teaching
Assistantships are also available.  Women and minority students are encouraged
to apply.

The Program in Applied Mathematics has 11 core faculty members and over 25
affiliated faculty whose research areas include Nonlinear Phenomena, Physical
Applied Mathematics, Computational Mathematics, and Discrete and Statistical
Mathematics.

The application deadline is Feb 1, 1995.  For further information please
