Midwest Undergraduate Mathematics Symposium

The 16th annual Midwest Undergraduate Mathematics Symposium (MUMS) will be held on Saturday, April 13, 2019, at Simpson College. The conference will feature contributed talks and poster presentations by undergraduates.  Our keynote speaker will be Raegan Higgins Siwatu from Texas Tech University.  Austin Mohr from Nebraska Wesleyan will be our afternoon plenary speaker.


  • Promote student engagement in the mathematical sciences, including projects and research (completed individually or in groups).
  • Provide students the opportunity to share and celebrate the work they have completed in the mathematical sciences.
  • Introduce students to topics and applications of mathematics that are new to them.
  • Inform students about research programs and study abroad opportunities in the mathematical sciences.
  • Inform students about career and graduate school opportunities in the mathematical sciences.

Continuous, Discrete, or Somewhere in Between: Time Scales Calculus

Progress has been made in the unification and extension of discrete and continuous analysis since Stefan Hilger's seminal paper in 1988.  The general idea is to prove a result once for a dynamic equation where the domain of the unknown function is an arbitrary, nonempty, closed subset of the real numbers called a time scale 𝕋.

Using the exponential function ept we will introduce to the theory of time scales. We will then use the fact that ept is the solution of x'=pxx(0)=1 to define a generalized exponential function on a time scale 𝕋 and derive several important properties of the generalized exponential function. Examples and applications will be given.

Dr. Raegan Higgins Siwatu is an Associate Professor of Mathematics in the Department of Mathematics & Statistics at Texas Tech University (TTU). Her current research focuses on oscillation criteria for certain linear and nonlinear second order dynamic equations on time scales. While she is also interested in applications of time scales, Dr. Higgins has a keen interest in increasing the number women, especially those underrepresented, in STEM and improving the undergraduate preparation of mathematics majors.  She is a proud alumnus of Xavier University of Louisiana, where she graduated summa cum laude with a B.S. in Mathematics.  In 2008, Dr. Higgins was one of the first two African-American women to earn a doctoral degree in Mathematics from the University of Nebraska- Lincoln.

Creating the Ideal Guest List

In an effort to host a party with the perfect balance of familiarity and novelty, we try to invite guests so that no three are mutual strangers and no three are mutual acquaintances. After hours of hard work, we are unable to find even six guests fulfilling these two simple criteria. We start to suspect it is impossible, but how would one prove such a claim? This seemingly unremarkable question will propel us from basic combinatorial theory, beyond the limits of computation, and to the development of entirely new areas of mathematical research.

Austin Mohr is Associate Professor of Mathematics at Nebraska Wesleyan University and a 2014 MAA Project NExT Fellow. He is passionate about enriching undergraduate mathematics education through research experiences, active learning, and growth-oriented communities. He enjoys working on problems in combinatorics and computer science, especially those he can share with students. He also enjoys insisting that his approach to writing exams is the only correct one, but don't ask him about that unless you have some time to spare.


Registration form

There is no registration fee, but we do request that you register in advance by March 29.

Call for Presentations

Undergraduate students are invited and encouraged to make presentations in any mathematics-related field. Possible topics for talks and posters include, but are not limited to:

  • results of class projects;
  • solutions to contest problems (Putnam Exam, modeling competitions, etc.);
  • results from undergraduate research projects (summer programs, capstone courses, etc.);
  • expository talks on interesting topics in mathematics;
  • papers on the history of mathematics;
  • mathematics education projects; and
  • independent work in mathematics, statistics, computer science, or related disciplines.

Abstract Submission

Abstracts are due by Friday, March 29, 2019.  Abstract submissions must include the following information:

  • names of all presenters and their schools;
  • title of the presentation;
  • brief abstract (one paragraph);
  • your preference for a talk or poster presentation; and
  • faculty sponsor(s).

We have a limited number of time slots available for student talks, but a larger capacity for poster presentations.  Please submit your title and abstract by filling out our registration form (link above).  To see abstracts from previous years, click on "MUMS 2017 Abstracts" below. If you have any questions, contact Dr. Katherine Vance or Dr. Murphy Waggoner.
