Given a degree d and a rational prime p, we search for the smallest non-trivial height of a totally p-adic number of degree d. If d = 2, then the smallest height depends on the congruence of p mod 5. If d = 3, then instead of a congruence condition on p, we have an algorithm which can find the smallest height for a particular prime. What is so different about degree 2 numbers and degree 3 numbers? All degree 2 numbers have abelian Galois group, whereas the same cannot be said for algebraic numbers of degree 3.

We continue our analysis of evolutionary models aimed at explaining partial migration, the phenomenon where some individuals in a population migrate between breeding seasons, but others do not. Whereas we showed before that partial migration can be caused by negative density dependence alone, we will now consider the effects on partial migration of how density dependence acts: within-types, between-types, or a mixed form.

Tsunami loading can cause sediment instability, which can compromise the structural integrity of coastal buildings and infrastructure. To understand the process by which a tsunami can cause sediment instability, it is necessary to understand how the pore water pressure in the soil changes during tsunami loading. Based on the changes in pore water pressure due to overlying water and seepage of infiltrating water during a tsunami, a deformation model was developed and coupled with a seepage model.

Graduate students expecting to graduate in the Spring or Summer term should: 1) apply for graduation by April 7, 2017, by logging into your MyOSU, go to Student Records, and Apply for Graduation; 2) if attending commencement, confirm attendance by April 28, 2017; 3) dissertation titles for Ph.D. students attending commencement and completing their degree either spring or summer should be send to Julie.Kurtz@oregonstate.edu no later than April 20, 2017. The Graduate School is continuing to allow graduate students completing their degrees during summer term to participate in the...

The poster session is back! Graduate Committee and the Math Club encourage Mathematics students to present their research and other mathematics activities in a poster session to be organized at the Lonseth Lecture http://www.math.oregonstate.edu/lonseth and Mathematics Awards day on May 2, 2017. A poster session is a great way to showcase your activities, and to practice for future presentations.

The session is less than a month away, so start preparing, and stay tuned for details!

Registration is required by April 26 at http://oregonstate.qualtrics.com/jfe/form/SV_3HMqTzuLH8ev0KV...

The Graduate Committee is pleased to announce that Zack Reed and Emerald Stacy have been awarded Oregon Lottery Scholarships for 2017-18. Please join us in congratulating Zack and Emerald!

It is a pleasure to report further news on student travel.

Joe Umhoefer attended the CASCADE RAIN Meeting (with Cascade RAIN funding) at Simon Fraser University April 8, 2017, where he presented a talk.

Zachary Barry participated in Stanford Undergraduate Research Symposium April 14-15, 2017 (with partial funding) where he presented a poster. Zach is an OSU Mathematics undergraduate who is participating in the Accelerated Masters Platform program and will be joining the department as a GTA next Fall while working towards his MS degree.
