The fall meeting of the Iowa Section of the Mathematical Association of America will feature MAA Secretary James Sellers from the University of Minnesota-Duluth and MAA AWM speaker Catherine Hsu from Swarthmore College. They will give invited talks on Saturday. Dr Sellers will speak in the morning after the welcome, which will start at 8:15am CDT. Dr Hsu will speak in the afternoon after concurrent sessions from 2:30pm to 3:30pm CDT to close out the meeting. The business meeting will take place from 9:30am to 10:30am CDT, and there will be a lunch break from 11:40am to 12:40pm CDT. Dr Angela Kohlhaas will give her Section Teaching Award plenary address from 12:40pm to 1:10pm CDT.

James Sellers talk, Saturday 8:30–9:30am CDT: Revisiting What Euler and the Bernoullis Knew About Convergent Infinite Series

All too often in first-year calculus classes, conversations about infinite series stop with discussions about convergence or divergence. Such interactions are, unfortunately, not often illuminating or intriguing. Interestingly enough, Jacob and Johann Bernoulli and Leonhard Euler (and their contemporaries in the early 18th century) knew quite a bit about how to find the exact values of numerous families of convergent infinite series. In this talk, I will show two sets of exact results in this vein. The talk will be accessible to anyone interested in mathematics.

Catherine Hsu talk, Saturday 2:30–3-30pm CDT: Projective and Non-Abelian SET

Mathematicians love SET. On the surface, this classic game is a con test of pattern recognition, but it also presents an interesting way to visualize the geometry of a torus over a finite field. In this talk, we will discuss some of the mathematics connected to SET and then explore several new versions of the game, including one arising from projective geometry and one arising from non-abelian groups. In particular, we will see how these non-abelian variations on SET can give intuitive visualizations of abstract group structures.

IA section database

We are trying to maintain an up-to-date database of all section members to provide better communication, save expenses on mailings, and help with the registration and proposal process. If you have not already updated your information, you may do so by using the log in page here. The credentials that you need here are your email and your password. If you forgot your password, you can always have it sent to by using the "I forgot my password" link on the log in page (log in). This assumes that you are in the system.
