SUMMARY:Using quantum statistical mechanical systems to study real quadratic fields (Jane Panangaden\, Pitzer College)
DESCRIPTION:The original Bost-Connes system was constructed in 1990 and is a QSM system with deep connections to the field of rationals. In particular\, its partition function is the Riemann-zeta function and its ground states evaluated on certain arithmetic objects yield generators of the maximal Abelian extension of the rationals. In this talk we describe the construction of a related QSM system adapted to the study of real quadratic fields\, called the Boundary GL2 System. We describe its thermal properties and show how these relate to class field theory of real quadratic fields. These results are joint work with Matilde Marcolli.

SUMMARY:Graph Complexes and Moduli Spaces of Curves (Siddarth Kannan\, UCLA)
DESCRIPTION:Title: Graph Complexes and Moduli Spaces of Curves \nSpeaker: Siddarth Kannan\, UCLA \nAbstract: I will begin by defining a certain combinatorial object called a graph complex. Then I will give a brief introduction to the moduli space of curves. The study of the geometry of this moduli space has occupied several generations of mathematicians\, across fields such as algebraic and differential geometry\, mathematical physics\,  geometric group theory\, and more. Finally\, I will describe the beautiful connection between the graph complex and the topology of the moduli space. \n\n\n\n\n\nI am currently a postdoc at UCLA. I obtained my PhD from Brown University in 2023\, after graduating from Pomona College in 2018. I first became interested in the combinatorial aspects of algebraic geometry while working with Prof. Dagan Karp as an undergraduate.

SUMMARY:Claremont Topology Seminar: Song Yu (Caltech)
DESCRIPTION:We welcome all undergraduates and graduate students to attend topology seminar! \nSpeaker: Song Yu (California Institute of Technology and Tsinghua Yau Mathematical Sciences Center) also a Pomona alum! \nTitle: Knot invariants\, Gromov-Witten invariants\, and integrality conjectures \nAbstract: In this talk\, we will take a peek at large N duality which is a deep correspondence between invariants of knots in 3-manifolds and enumerative geometry in symplectic 6-manifolds discovered in physics in the 1980-90s. On the numerical level\, the correspondence relates Chern-Simons knot invariants to open Gromov-Witten invariants which are counts of bordered Riemann surfaces with Lagrangian boundary conditions\, and has led to predictions on the integrality structures of both invariants. We will discuss recent progress on the enumerative geometry side and connections to known integrality properties in Gromov-Witten theory. \n  \n

SUMMARY:Math as Art and Recreation (Peter Kagey\, HMC)
DESCRIPTION:Title: Math as Art and Recreation \nSpeaker: Peter Kagey\, HMC \nAbstract: Recreational Mathematics is an area of math which is rooted in exploration and playfulness\, and includes puzzles\, games\, art\, and more. This talk takes a closer look at these ideas\, emphasizing how a foundation of curiosity and play can lead to insightful connections with various branches of mathematics\, fostering a deeper appreciation for both the beauty and the enjoyment inherent in mathematics. Illustrating this\, I will describe how a question from Martin Gardner ultimately led to theorems in group theory and combinatorics\, demonstrating the unexpected bridges that can be built between recreational puzzles and deeper mathematical concepts. \n\n\n\n\n\nPeter Kagey is a Visiting Assistant Professor from Harvey Mudd College. He received his Ph.D. from the University of Southern California in 2022. Since 2019\, he has been an Associate Editor with the On-Line Encyclopedia of Integer Sequences. His research interests include combinatorics and algebra\, along with discrete\, experimental\, and recreational mathematics. He is passionate about cultivating a culture of joy\, curiosity\, and care in the mathematics community.
