The University of Portland, including the College of Arts and Sciences and the Mathematics Department, is proud to host the 2019 Spring Meeting of the Pacific Northwest Section of the Mathematical Association of America. Our faculty and students are excited to support the section's activities which promote vigorous research and dynamic teaching and learning in our region.  Please accept our warm welcome to Portland; we hope you enjoy all we have planned.  Please contact the department, or e-mail if you have any questions regarding the meeting.

Invited Program Information:

Friday night public lecture:  T.B.A Carlos Castillo-Chavez, Arizona State University.

Saturday morning lecture: ``Writing Numbers as the Sum of Factorials.''  Su Doree, Augsburg College.

In standard decimal notation, we write each integer as the linear combination of powers of 10.  In binary, we use powers of 2.  What if we used factorials instead of exponentials?  How can we express each integer as the sum of factorials in a minimal way? This talk will explore the factorial representation of integers, including historical connections to permutations, a fast algorithm for conversion, and the secret of the “third proof by mathematical induction.”  Next we’ll extend this representation to rational and then real numbers, ending with some remaining open questions.
Saturday afternoon lecture:  T.B.A Carlos Castillo-Chavez.

Saturday evening talk: T.B.A.  Brian Katz, Augustana College.

Contributed Papers and Student Presentations:

Abstracts for special and general paper sessions are due March 1st and should be e-mailed to Please use the LaTex template, or a Word document or .pdf that contains the name and affiliations(s) of the presenter and author(s), talk title, and a short abstract.

Hotel and Travel Information:

 The organizers have arranged room rates at The Fairfield Inn and Suites and The Courtyard Portland North Harbour.  Rooms are available at both hotels at a reduced base rate of $139 and $149, respectively, on a first-come basis.  A direct link to book at either of these Marriot properties at the conference rate is available here.  There are a number of recently constructed boutique hotels nearer campus, as well as a number of hotels in the Rose Quarter and Downtown Portland.
