The Department of Mathematics weekly seminar series, Math Talks, is open to all KSU faculty, students, and invited visitors to present any math or math-related topic. Seminars typically require little or no advanced mathematical knowledge are open to anyone.

- "Exploring fractions"
- ABSTRACT: Not many people are excited about fractions. In fact, many people seem to dislike fractions. In this Math Talk, we will explore a couple of curious patterns in fractions. This session will not require any advanced mathematics beyond high school algebra. You just need to be willing to tackle a couple of problems.

- "Lloyd Shapley, College Admissions and the Stability of Marriage"
- ABSTRACT: In this talk, I will present the paper “College Admissions and the Stability of Marriage” by David Gale and Lloyd Shapley. This short paper contains groundbreaking work on the problem of making efficient stable assignments – such as assignments of students to colleges and assignments of marriage partners. The algorithm developed in the paper later went on to find applicability in many other kinds of matching problems such as the assignment of medical interns to hospitals and the matching of kidney donors to recipients. The paper was published in The American Mathematical Monthly in 1962 and it has since received the second highest number of citations of all papers published in The Monthly. It was also cited by the Royal Swedish Academy of the Sciences when Shapley was awarded a Nobel Prize in Economics in 2012. To honor that occasion and to introduce a new generation to this paper, The Monthly published it again in 2013. The questions concerning stable and optimal assignments that are addressed in this paper are easily explained, even to one has no formal mathematical background, and the reasoning that Gale and Shapley use to answer these questions is very “common sense” and elegant. The paper is only 7 pages long so, if you have time, you may want to read it before the talk. My talk will be designed for students and I believe that it will be accessible (and hopefully also enjoyable) to everybody in its entirety.

- "Secrets of Pascal's Triangle"
- ABSTRACT: Pascal’s Triangle is an arrangement of binomial coefficients, which have an endless number of interesting properties. Many of these properties are related to the structure of Pascal’s Triangle. This talk will begin with basics. We will continue with recent discoveries, such as how e and pi can be calculated using Pascal’s Triangle. The Fibonacci numbers have several connections to Pascal’s Triangle, and we will also show recently discovered connections between Pascal’s triangle and the Delannoy numbers.
