Kyen Waldron worked on the paper with Suzy Reichel in the NSF funded Reserach Experience for Undergraduates program at Tulane University during the summer of 1999. Our faculty advisor was James Rogers. She will graduate from the University of Oregon in June 2000 with a bachelor of arts in mathematics and will pursue a masters degree in mathematics from the University of Oregon beginning in fall 2000. She also plan to obtain a teaching certificate and will probably go into mathematics education.
