In celebration of Pi Day (March 14, or 3/14), Math Club posted the digits of pi (3.14…) down the JBWS stairs — photos below!

## Putnam results

Amira Mahler became the third SEU student in the past decade to earn a positive score on the Putnam exam. There are thousands of math majors nationwide who score 0 points every year due to the hyper-strict grading scale, so any positive score is a noteworthy accomplishment. Congratulations!

Problems and solutions from 2017 and past exams are available at http://kskedlaya.org/putnam-archive/

Official results and press release are at https://www.maa.org/programs-and-communities/member-communities/maa-awards/putnam-competition-individual-and-team-winners

## Math major, faculty attend Geometry of Redistricting Workshop at UT-Austin

Math major Omar Dominguez and faculty Drs. Jason Callahan, Kaitlyn Phillipson, and Michael Saclolo attended the Geometry of Redistricting Workshop at The University of Texas-Austin February 3-4.

This was a regional workshop of the Metric Geometry and Gerrymandering Group, a Boston-based team of mathematicians launched by Dr. Moon Duchin of Tufts University, whose mission is to study applications of geometry and computing to U.S. redistricting under the belief that gerrymandering of all kinds is a fundamental threat to our democracy.

In our MATH 4157 (Research) seminar on February 9, Omar, under the mentorship of Dr. Callahan, then presented a recent paper entitled “A Formula Goes to Court: Partisan Gerrymandering and the Efficiency Gap” by Dr. Duchin on the efficiency gap as a measure that has successfully been used in court to show gerrymandering in Wisconsin and is now headed to the Supreme Court.

Omar plans to continue research on this topic with Dr. Callahan over the next two years, and Dr. Duchin is now helping redraw gerrymandered voting districts in Pennsylvania, making this a timely and important research topic.

## Math Faculty’s work published

Dr. Jason Callahan recently had a mathematical poem published in *the Journal of Humanistic Mathematics* collection “Math in Seventeen Syllables: a Folder of Mathematical Haiku” (Volume 8, Issue 1, page 447, January 2018). You can view the collection here.

Congratulations to Dr. Callahan!

## Math majors earn travel grants to present at Joint Mathematics Meetings

Math majors Maria Mota, Amira Mahler, and Stephanie Thrash earned Mathematical Association of America (MAA) Student Travel Grants to present their research at the Joint Mathematics Meetings (JMM) Student Poster Session in San Diego on January 12, 2018. JMM is the largest mathematics meeting in the world. Maria and Amira conducted their research with Dr. Jason Callahan, and Stephanie conducted her research with Dr. Mitch Phillipson. All three were partially supported Dr. M. Jean McKemie Endowed Student/Faculty Fund for Innovative Mathematics Summer Scholarships and NSF grant #1525490. Dr. Michael Saclolo also presented at JMM in the MAA Session on Mathematical Themes in a First-Year Seminar on January 11.

## Recording-breaking 12 SEU students participate in Putnam Competition

On December 2, organized by Dr. Edward Early with the help of Dr. Matthew Shirley, Monica Cicciarelli, and Sarah Reyna, a record-breaking twelve SEU students participated in the William Lowell Putnam Mathematical Competition, the preeminent mathematics competition for undergraduate college students in the United States and Canada:

Grace Akomezogho

Jacob Belmares

Elias Bocanegra

Antoine Chamoun-Farah

Brianna Collins

Omar Dominguez

Sarah Goldrup

Ayesha Gonzales

Amira Mahler

Agnes Mirando

Ivan Mota

Skyler Young

The Putnam Competition occurs annually on the first Saturday of December. The competition consists of two three-hour sessions, one in the morning and one in the afternoon. During each session, participants work individually on six challenging mathematical problems.

The Putnam began in 1938 as a competition between mathematics departments at colleges and universities but has since grown to be the leading university-level mathematics examination in the world. Although participants work independently on the problems, there is a team aspect as well. Prizes are awarded to participants who score the highest and to the departments whose teams rank highest. Congratulations to all our students who participated, and thanks to Dr. Early for organizing it!

## Math Club Pumpkin Carving

On Friday, October 29, Math Club hosted a pumpkin carving event. Together, we carved 8 pumpkins and displayed the results outside JBWS.

## TUMC 2017

This year the Texas Undergraduate Math Conference was held at Incarnate Word in San Antonio on October 21, 2017. Dr. Mitch and Dr. Phillipson chaperoned 12 students. We had 5 students give 4 separate talks. The talks were:

- Bianca Salinas and Stephanie Thrash – A Combinatorial Approach to RNA-Inspired Foldings
- Maria Mota – Solving 2-by-2 Scramble Squares Puzzles with Repetitions
- Amira Mahler – American Roulette: How Long and Boldly Can You Play
- Sarah Goldrup – A New Lower Bound on Unstable Neural Codes

## Lucian Symposium 2017

Seven math major students presented 5 posters at this year’s Lucian symposium.

- Adrian Silva and Juliette Garcia – Troposheric Ozone Pollution Project Workshop in El Paso
- Amira Mahler – American Roulette: How Boldly Can You Play?
- Maria Mota – Solving 2×2 Scramble Squares Puzzles with Repetitions
- Antoine Chamoun-Farah – Optimization of Lignin Depolymerization for R. opacus Bioconversion
- B Salinas and Stephanie Thrash – A Combinatorial Approach to RNA-Inspired Folds
