SUMMARY:Deniz Sarikaya on Narratives of Mathematical Practice (and why they matter!)
DESCRIPTION:Deniz Sarikaya joining us from the Technical University of Denmark and speaking on “Narratives of Mathematical Practice (and why they matter!)” (abstract below).\n \nThe speaker will join via zoom\, but there will be a live audience on the second floor of Pitzer College’s Gold Student Center in the Multipurpose room (in the building marked 3 here: https://www.pitzer.edu/about/maps-directions/quick-reference-map/).\n\nabstract:\nThere are different narratives on mathematics as part of our world\, some of which are more appropriate than others. Such narratives might be of the form ‘Mathematics is useful’\, ‘Mathematics is beautiful’\, or ‘Mathematicians aim at theorem-credit’. These narratives play a crucial role in mathematics education and in society as they are influencing people’s willingness to engage with the subject or the way they interpret mathematical results in relation to real-world questions; the latter yielding important normative considerations.\nIn this talk\, we want to analyze different narratives of mathematics and suggest that mathematizing as a virtuous practice in its own right is a better narrative of mathematics than\, for example\, extrinsic narratives which focus on the results of mathematical activity and the application of mathematics in non-mathematical contexts. By ‘better’ we mean that the mathematizing-narrative describes mathematical practice more adequately and that it allows for a shift in mathematics education that yields beneficial outcomes for our society. This is heavily drawing on Freudenthal’s Realistic Mathematical Education.\n \nThe talk is based on joint work with Deborah Kant (University of Hamburg)

SUMMARY:Robust properties of graphs (Asaf Ferber\, UC Irvine)
DESCRIPTION:In this talk we will consider some notions of `robustness’ of graph/hypergraph properties. We will survey some existing results and will try to emphasize the following new result (joint with Adva Mond and Kaarel Haenni): The binomial random digraph $D_{n\,p}$ typically contains the minimum between the minimum out- and in-degrees many edge-disjoint Hamilton cycles\, given that $p\geq \log^C n/n$. The result is optimal up to log factors.

SUMMARY:How Many Cards Can Avoid a SET? (Prof. Mohamed Omar\, Harvey Mudd College)
DESCRIPTION:Title: How Many Cards Can Avoid a SET? \nSpeaker: Mohamed Omar\, Department of Mathematics\, Harvey Mudd College \nAbstract: SET is a popular real-time card game where players search for special triples of cards among a table of cards that are face-up. A common issue when playing the game is not having a SET among theface-up cards. What is the maximum number of cards that can be face-up while avoiding a SET? Surprisingly\, this question is at the heart of a decades old central problem in extremal combinatorics and additive number theory that had a major breakthrough in 2017. In this talk\, we describe the breakthrough\, and how the presenter used ideas in its development to make headway on a range of disparate problems in combinatorics. \n\n\n\n\n\nDr. Mohamed Omar is an Associate Professor of Mathematics\, Associate Chair of Mathematics and the Joseph B. Platt Chair in Effective Teaching at Harvey Mudd College. He has received national awards for his research\, including being the inaugural recipient of the American Mathematical Society’s Claytor-Gilmer Fellowship and an inaugural recipient of the Karen EDGE Fellowship\, both celebrating mid-career research. He has also earned the Henry L. Alder Award\, the preeminent junior faculty national prize given by the Mathematical Association of America. He is the author of over 30 peer-reviewed articles in internationally recognized journals\, studying the interaction between algebra and combinatorics.

SUMMARY:The Hilbert space approach in the theory of differential equations (Adolfo Rumbos\, Pomona College)
DESCRIPTION:In this talk we discuss the Hilbert space approach\, or the variational approach\, in the study of questions of existence and multiplicity for some two-point boundary-value problems for nonlinear\, second order\, ordinary differential equations (ODEs).  We illustrate the use of the Hilbert space approach in obtaining some old existence results for periodic solutions of a semilinear ODE\, and some recent multiplicity results for a related problem. The talk is based on joint work with Noah Benjamin (Pomona College ’23) and Leandro Recôva (Cal Poly Pomona).
