**Medieval Math Mystery to Teaching Math Among Scholarly Works**

May 15, 2017

The research work of undergraduate mathematics major **Isabel Serrano** and her faculty mentor, mathematics professor **Bogdan Suceavă**, was selected for the anthology "The Best Writing on Mathematics 2016."

Published every year by Princeton University Press, the collection features "the best" mathematics writing from around the world, including their article, "A Medieval Mystery: Nicole Oresme’s Concept of Curvitas." The article was originally published in 2015 in Notices, the peer-reviewed journal of the American Mathematical Society.

Serrano plans to graduate in May 2018 with majors in mathematics and history. Suceavă, who also has a prolific literary career, wrote his sixth novel, "The Republic," recently released in Romania. The novel tells the story of an attempted coup d'etat from August 8, 1870, in the old Romania. He also has accepted the invitation of the Romanian newspaper*Daily Event*to write a weekly column.

**Pacific Math Alliance**

**Amy Feaster**and

**Eric Flynn**gave a presentation at the Pacific Math Alliance undergraduates research symposium at CSU Northridge on April 23, 2016. Amy, Eric, and mentor

**Dr. Alfonso Agnew**were awarded an NSF supported Pacific Math Alliance Undergraduate Research Group Grant for the 15-16 academic year, in order to continue their work on the topology and application of biquaternionic projective spaces. Amy is a graduating math major and physics minor planning to go to graduate school next fall. Eric is a math and physics double major. Both are student members of the College of NSM's Gravitational Wave Physics and Astronomy Center (GWPAC).

**Chapman University Colloquium**

CSUF undergraduate math major **Isabel M. Serrano** delivered a colloquium talk at Chapman University on Monday, April 18, 2016, for the Department of Mathematics and Computer Sciences (Von Neumann Hall, 545 West Palm). Her talk was titled *Geometry in the Dark Ages* and is based on two papers that were co-authored with faculty mentor **Bogdan D. Suceavă** (an article published by *Notices* of the American Mathematical Society) and with **Lucy H. Odom** and **Bogdan D. Suceavă** (will appear in the Mathematical Intelligencer).

**MAA Southern California-Nevada Spring Meeting**

Mathematics undergraduate student** Evelyn Easdale** was presented with a Meritorious Poster Award at the Spring 2016 Southern California-Nevada MAA Conference at Loyola Marymount University on April 2, 2016. Her poster,* A Criterion of Convergence for Series with General Term Defined by a Recurrence Relation*, was mentored by mathematics faculty members **Jolene Fleming** and **Bogdan Suceavă**. Evelyn’s research project on the series whose convergence is undecided by the Ratio Test was born out of her classwork in her advanced real analysis class. The paper written by Evelyn Easdale with Jolene Fleming and Bogdan Suceavă will appear in American Mathematical Monthly.

In addition to Evelyn, CSUF was represented by five other young mathematicians:
