Technical Reports

Preface

This page contains the technical reports written by the students who participated in the 1999 Summer Institute in Mathematics for Undergraduates (SIMU) at the University of Puerto Rico – Humacao.  SIMU is a six-week summer undergraduate research program whose target population is Latino and Native American students from the United States and Puerto Rico. 

The goal of SIMU is simple: to increase the number of Chicanos/Latinos and Native Americans earning Masters, Ph.D.’s, and pursuing research careers in the mathematical sciences.  We believe that one way to try to achieve this goal is by bringing together a group of talented students and challenging them to engage in quality mathematical research in an intense, supportive and collaborative environment.  The reports contained herein are the culmination of hundreds of hours of work by the 1999 SIMU students during the six weeks of the program.

The twenty-four students who participated in the 1999 SIMU worked in groups of three on undergraduate research projects in two active and exciting areas in the mathematical sciences.  The projects in the area of Gröbner basis were directed by Professor John B. Little from College of the Holy Cross; and those in the area of probability and statistics were directed by Professor Rudy Guerra from Southern Methodist University.  Because the quantity of work produced by these students during the six weeks of the program is so great and because of other time constraints, these technical reports are for the most part unedited.

The 1999 SIMU was funded by grants from the National Security Agency (NSA Grant # MDA904-99-1-0041), the National Science Foundation (NSF Grant # DMS-9907887), the University of Puerto Rico, the National Aeronautics and Space Administration (NASA), the Alliance for Minority Participation (AMP), and the Society for Advancement of Chicanos and Native Americans in Science (SACNAS).

1999 SIMU Technical Reports

Note on Format: All the abstracts and papers can be downloaded in either PDF or DVI format.  The abstracts should download without any complications.  There are some drawbacks to each format for the papers that contain graphics.  Our DVI --> PDF converter, chooses to ignore EPS image files, so the PDF versions may be missing some graphics.  In order for the DVI file to print correctly, it requires any image files associated with it to be copied to the same directory on your hard drive as the DVI file.  So if you choose to download the DVI file, make sure and download any image files associated with the paper to the same folder/directory on your hard drive.

If you would like a hard copy of any of the papers, please send your request to simu@cuhwww.upr.clu.edu.
