2008 Spring/Summer
The Oregon Invitational Mathematics Tournament (OIMT) is an annual tournament for Oregon high school mathematics students, hosted in rotation by the mathematics departments of Willamette University, Portland State University, the University of Oregon, and Oregon State University. This year, the event is hosted at Willamette University on Saturday, May 17, 2008. Entry is by invitation, primarily based on students' achievement at regional math contests offered around the state by many community colleges and other schools during the spring.
The Willamette Valley Consortium for Mathematics Research (REURET) is an 8 week summer research experience for undergraduate math students and teachers of mathematics. REURET is supported by the National Science Foundation (NSF), Willamette University, Lewis and Clark College, Linfield College, and the University of Portland. This year’s event is hosted at Willamette University June 16  August 8, 2008.
2007 Fall  Updated: October 17, 2007
Jessica John, who graduated in 2006 majoring in mathematics and who appeared in the news section often for her superior records at Willamette, was featured in The Oregonian's "A chat with an interesting, influential or innovative voice in Oregon business" on October 16.
Dr. Josh Laison is a new assistant professor at the Math Department. During the previous year, he was a visiting assistant professor at St. Olaf College and published two articles including "My Experiences Researching With Undergraduate Mathematicians: The Collaboration Model." The paper appeared in the AMS’s Proceedings of the Conference on Promoting Undergraduate Research in Mathematics in June and should be particularly interesting to students. Another "Seeing Dots: Visibility of Lattice Points" coauthored with his former student will appear in the October issue of Mathematics Magazine. Welcome to Willamette!
2007 Summer
Professor Peter Otto gave a talk entitled "The Random Cluster Model" in the University of Vermont/Saint Michael's College Combinatorics Seminar on June 27. He also attended a NITLE workshop on Bioinformatics in the Undergraduate Curriculum at Bates College on July 1920.
2007 Spring
Apology from site webmaster: This year I have failed to name the proud students who received the mathematics awards and scholarships; I am sorry. Could someone in the department please provide me with the names?
Andrea Carlson, administrative assistant for the math department, was the winner of the campuswide award, 20062007 Classified Employee of the Year. Don’t forget to congratulate her when you visit her and see the nice looking plaque on her desk in Collins Hall 203.
Professor Johnner Barret resigned after four years of teaching at Willamette. He plans to complete his ongoing research project and finish his Ph.D. program at Oregon State University. Good luck!
Professor Peter Otto coauthored an article entitled “Multiple Critical Behavior of Probabilistic Limit Theorems in the Neighborhood of a Tricritical Point” with Richard S. Ellis of the Department of Mathematics at the University of Massachusetts and Marius Costeniuc of Max Planck Institute for Mathematics in the Sciences. It was accepted for publication by the Journal of Statistical Physics and will appear late this year. Congratulations!

Professor Inga Johnson and Professor Colin Starr appeared in the spring issue of the Willamette Scene for receiving a $491,400 grant from the National Science Foundation and providing the REURET summer program; see the headline below.
Professor Inga Johnson and Professor Colin Starr organized REURET, an NSF funded summer research program of a grand scale for undergraduate math students and teachers of mathematics. The program that runs from June 18 through August 10, 2007, involves four consortium schools, Willamette University, Lewis & Clark College, Linfield College, and the University of Portland, each of which will host a research team of four undergraduates, one teacher, and two faculty mentors. Each research team will focus on a project from faculty research interests in number theory, geometry, abstract algebra, or computer science, and the four teams will meet on Thursdays for invited speaker presentations, progress discussions, and social activities. For additional information and application forms, visit the program website REURET. Contact Professor Johnson or Professor Starr if you have questions.
Professor Erin McNicholas was invited by the Ohio State University's Applied Mathematics Seminar to give a talk entitled “Embedded Tree Structures and Eigenvalue Statistics of Genus Zero, OneFace Maps” in January.
Mathscot Pooka belonging to Professor Emeritus Sam Hall passed away in January. Here is a tribute by Professor Hall: “She was born in December of 1989 and served loyally as the first departmental mathscot for more than 15 years. We hope her caring attitude toward students and her readiness to protect the department against all unwelcome intruders will live on in her successors.” The current mathscots are Dakota and Jack, whose pictures are shown in Math Faculty.
Like a year ago, this year’s spring semester kicked off with several colloquium talks by visiting scholars. For detail, see Mathematics Colloquium, 20062007.

They explained to the general audience the nature and some of the major areas of research in mathematics, and discussed the undergraduate research they had directed over the last two summers. Note: The seminars and colloquia scheduled within the Mathematics Department together with their abstracts are now listed in Mathematics Colloquium, 20062007.
The Basic Notions Seminar (see 2004 Fall) has evolved into Mathematics Colloquium, 20062007, which comprises a series of talks by the Willamette math department and by visiting scholars. These talks are aimed at faculty and undergraduate math students and will introduce the audience to fun, interesting applications of undergraduate mathematics, as well as more advanced topics in mathematics research. For more information, check out Mathematics Colloquium, 20062007, or contact either of the program coordinators, Professors Inga Johnson and Erin McNicholas.

Dean Carol Long congratulated three faculty members including Professor Inga Johnson for receiving Junior Faculty Sabbatical Awards on March 20. As a result, Professor Johnson will be taking next fall semester off from teaching responsibilities and concentrate on her ongoing research project generalizing recent results in the Steenrod algebra at the prime 2 to the odd primary case. The Steenrod algebra is an important object of study in cohomology and homotopy theory, which are subjects in the area of mathematics called algebraic topology.
Math Club celebrated p day on March 14 beginning at 1:5926535897932384626433832795028 pm sharp (or flat?).
