Professor and Fields medalist Hugo DuminilCopin will give two talks for the 2024 Stelson Lecture series: "From Coffee to Mathematics: Making Connections and Finding Unexpected Links," a public lecture on March 7 designed to be accessible to a wide audience, as well as a School of Mathematics Colloquium on March 8 focused on the Ising model.
Public lecture:
From Coffee to Mathematics: Making Connections and Finding Unexpected Links
March 7, 2024
Welcome reception: 4 p.m.
Lecture: 4:30  5:30 p.m.
Location: HoweyPhysics L3
No RSVP required
The game of HEX has deep mathematical underpinnings despite its simple rules. What could this game possibly have to do with coffee, and how does that connection, once identified, lead to consideration of ferromagnetism and even to the melting polar ice caps? Join Hugo DuminilCopin, Professor of Mathematics at Institut des Hautes Études Scientifiques (IHES) and the University of Geneva, for an exploration of how mathematical thinking can help us make some truly surprising connections.
Colloquium:
Critical phenomena through the lens of the Ising model
March 8, 2024
Time: 11 a.m.
Location: Skiles 006
The Ising model is one of the most classical lattice models of statistical physics undergoing a phase transition. Initially imagined as a model for ferromagnetism, it revealed itself as a very rich mathematical object and a powerful theoretical tool to understand cooperative phenomena. Over one hundred years of its history, a profound understanding of its critical phase has been obtained. While integrability and meanfield behavior led to extraordinary breakthroughs in the twodimensional and highdimensional cases respectively, the model in three and four dimensions remained mysterious for years. In this talk, we will present recent progress in these dimensions based on a probabilistic interpretation of the Ising model relating it to percolation models.
About the speaker
Professor Hugo DuminilCopin is a French mathematician specializing in probability theory, who studies the border between mathematics and physics and analyzes models of fluids flowing through a porous medium, such as water coursing through coffee grounds. Such models, which involve the formation of connected clusters in random networks, can also represent the spread of a disease, the circulation of a rumor, or the advance of a forest fire.
Professor DuminilCopin has diverse interests in a range of activities which also characterizes his work, and has sampled tools from various fields in an ongoing effort to transform mathematicians’ understanding of phase transitions.
For that work, DuminilCopin was awarded the Fields Medal in 2022 for "solving longstanding problems in the probabilistic theory of phase transitions in statistical physics, especially in dimensions three and four".
About the Stelson Lecture Series
Thomas Stelson was a distinguished civil engineer who served as dean of the College of Engineering at Georgia Tech from 1971 to 1974, as vice president for Research from 1974 to 1988, and as executive vice president from 1988 to 1990.
During the 1970s and 1980s, Stelson oversaw a vast expansion in Georgia Tech's research expenditures in an era when Tech transformed from a primarily teachingoriented university to a major research institution.
Stelson helped the School of Mathematics create the Center for Dynamical Systems and Nonlinear Studies, and he endowed the School's Stelson lectures in 1988 in honor of his father, Hugh Stelson, who was a mathematician. Hugh Stelson earned his doctorate from the University of Iowa in 1930 and went on to teach at Kent State University and Michigan State University. He worked on problems related to interest rates, annuities, and numerical analysis.

Previous Stelson Lectures
Nonlinear Waves, Spectra, and Dynamics in Infinite Dimensions
Schlag, Wilhelm (Georgia Institute of Technology, 20230310)
Waves are ubiquitous in nature. Some wave phenomena are conspicuous, most notably in elastic objects, and in bodies of water. In electrodynamics, quantum mechanics, and gravity, waves play a fundamental role but are much more difficult to find...
Reunited: An Art Historical and Digital Adventure
Daubechies, Ingrid (Georgia Institute of Technology, 20220409)
Combining the mathematics of digital image processing with the history, craftsmanship, and science of art conservation, my research team at Duke University, Bass Connections Image Processing Algorithms for ...
Cryptography: From Ancient Times to a PostQuantum Age
Pipher, Jill C. (Georgia Institute of Technology, 20180301)
How is it possible to send encrypted information across an insecure channel (like the internet) so that only the intended recipient can decode it, without sharing the secret key in advance? In 1976, well before this ...
The Complexity of Random Functions of Many Variables
Arous, Gérard Ben (Georgia Institute of Technology, 20160831)
A function of many variables, when chosen at random, is typically very complex. It has an exponentially large number of local minima or maxima, or critical points. It defines a very complex landscape, the topology of its ...
How Quantum Theory and Statistical Mechanics Gave a Polynomial of Knots
Jones, Vaughan (Georgia Institute of Technology, 20140925)
We will see how a result in von Neumann algebras (a theory developed by von Neumann to give the mathematical framework for quantum physics) gave rise, rather serendipitously, to an elementary but very useful invariant in ...
Riemann, Boltzmann and Kantorovich Go to a Party
Villani, Cedric (Georgia Institute of Technology, 20130419)
This talk is the story of an encounter of three distinct fields: nonEuclidean geometry, gas dynamics and economics. Some of the most fundamental mathematical tools behind these theories appear to have a close connection, ...
Role of Mathematics Across Science and Beyond
Glimm, James (Georgia Institute of Technology, 20101122)
The changing status of knowledge from descriptive to analytic, from empirical to theoretical and from intuitive to mathematical has to be one of the most striking adventures of the human spirit. The changes often occur ...
Multiscale Modeling and Simulation: The Interplay Beween Mathematics and Engineering Applications
Hou, Thomas Y. (Georgia Institute of Technology, 20091026)
Many problems of fundamental and practical importance contain multiple scale solutions. Composite and nano materials, flow and transport in heterogeneous porous media, and turbulent flow are examples of this type. Direct ...
