Last Wednesday we had amazing presentations from four of our students, outlining how they had spent their summer---each one in a different way than the other three.

We would like to thank our speakers (in order of presentations):
-- Jack Haskins
-- Ashton Wine
-- Danyelle Taylor
-- Ronnie Cole

Check out the recording of all four right here!

For both---or either---of these talks (Abby's senior presentation or Dr. Bucher's research overview), come to CLC 406 or join us through Zoom Meeting # 95897104521. If Zooming in, make sure to use your Xavier credentials.

Pizza and drinks will be provided during the intermission :^)

Coming Wednesday, 11/17 @ 3:30pm:

Dr. Eric Bucher's "Introduction to cluster algebras and their applications"

Cluster algebras were first invented by Fomin and Zelevinsky in 2003. Since their inception, these mathematical objects have popped up in a large variety of seemingly unrelated areas including: combinatorics, topology, algebra and mathematical physics. In this talk we will lay the basic groundwork for working with cluster algebras as well as discuss a few of their applications to the above areas. This talk is intended to be introductory so no background or definitions will be assumed. The intention is to have everyone walk away having learned about this new and fascinating algebraic object.

Coming Wednesday, 11/17 @ 3pm:

Abby Brickner's "Mathematical Approach to Congressional Redistricting"

Gerrymandering has been a pertinent issue for politics and voting in the United States since its earliest days. In an attempt to analyze this political issue mathematically to automate a solution, we have created a number of simulations which run on the basis of four factors. These factors are fairness, competitiveness, equal population and compactness. The manipulation of these factors alongside a mutation algorithm allowed us to create maps which provide alternatives to the current districts. Further work focused more on the genetic algorithm and the idea of "survival of the fittest" regarding the crossover of the best parent maps to produce their offspring. Finally, manipulation of the fairness factor in combination with the genetic algorithm has allowed for simulations to show intentionally biased maps, either to favor the Republicans or the Democrats.

It's getting curiouser and curiouser. In addition to Eric's Mystery Talk (which is no longer a mystery to yours truly, but that's a story for another time), Abby will be presenting her Senior Project on the same day. Double delight, with some refreshments in-between.

Hope to see you all on Wednesday, 11/17. Keep an eye out for details.

Later this semester, on Wednesday, 11/17, our dear colleague, Eric Bucher, will make a presentation---of whatever it might be that he wants to talk about. Although the formal title is "Eric Bucher: Research Spotlight" (possibly reversed), one could wonder how deep he's going to dive into theoretical mathematics and if he's going to be able to keep the audience of undergraduate math students engaged throughout. Personally, yours truly is certain that he is. I've never seen such a charismatic presenter.

Mark it on your calendars: 11/17 @ 3pm, Bucher's Mystery Talk.

A couple of weeks ago, on 9/8, we had our "What I Did Over the Summer" session. We would like to share the recording of this session with you, where students who had any kind of math/actuarial science-related internship, research position, etc. over the summer talk about their experience... and not only students!

A special thank you goes to Lauren Talbot, who helped spread the word about this event---on a very short notice!
