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 ------------------------------------------------------- Date: Tue, 13 Sep 1994 03:54:23 -0600 (MDT) From: Steve McCormick Subject: NSF Traineeships at the University of Colorado at Boulder Craig, If this is appropriate for the mgnet airways, please include it in the next issue. Thanks! steve 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.
