SUMMARY:Federica Garin (Université Grenoble Alpes)
DESCRIPTION:Title: Graphons and opinion dynamics on large graphs. \nAbstract: \nGraphons are the limits of large dense graphs. Graphons can also be used to define families of random graphs (the so-called W-random graphs)\, similar to Erdős-Rényi random graphs but with some inhomogeneity in the edge probabilities. \nGraphons and W-random graphs\, together with their signed counterparts\, can be useful tools to study opinion dynamics on large-scale networks.  \nIn this talk\, I will review some recent work in this direction\, where we explore some infinite-dimensional dynamics associated with the graphon\, and we study how well they can approximate the corresponding dynamics associated with finite but large W-random graphs. \n  \nThis seminar will take place in Room S08 at the Faculty of Sciences.

SUMMARY:Thomas Koffel (Université Claude Bernard Lyon 1)
DESCRIPTION:Title: From Metacommunities to Masting: How Spatial Structure Privatizes Environmental Benefits \nAbstract:  \nIndirect positive interactions\, mediated by environmental modification\, are central to niche construction and cooperation. However\, eco-evolutionary theory predicts that when modified environments are fully public\, the ‘tragedy of the commons’ favors cheaters\, destabilizing such processes. This talk explores how spatial structure overcomes this barrier through two complementary lines of work. First\, using a minimal stochastic model\, we show how competition-colonization dynamics in a patch-structured metacommunity allow cooperators to coexist with or even exclude cheaters. Second\, we demonstrate how environmental privatization at the individual level enables niche construction\, specifically in the context of masting (intermittent\, synchronous fruiting by trees). By satiating and starving seed consumers—a ‘public bad’—masting evolves as a coordinated defense strategy that effectively privatizes the benefits of predator control. Together\, these results underline how the scale of environmental modification fundamentally dictates the scale at which selection acts in ecosystems. \nThis seminar will take place in Room S08 at the Faculty of Sciences.

DESCRIPTION:Title: Overview of quantum chemistry investigations into classically studied materials with potentially useful quantum properties \nListe de tous les auteurs : Harry Shaw1\, Deborah Preston1\, Virginia Ayres2\, Kyle Sherbert3\, Naveed Naimipour4\, Nick Savino6\, Manon Bart5\, Ryan Glasser6 \n(1) Xyngal Morph LLC\, Bel Air\, MD \n(2) Department of Electrical and Computer Engineering\, Michigan State University\, East Lansing\, MI\, USA \n(3) Department of Computer Science\, Holy Cross University\, Notre Dame\, IN\, USA \n(4) Engineering Faculty\, Wilbur Wright College\, Chicago\, IL \n(5) Namur Institute for Complex Systems\, University of Namur\, Namur\, Belgium \n(6) School of Science and Engineering\, Tulane University\, New Orleans\, LA\, USA \nAbstract:  \nWhile at NASA Goddard Space Flight Center\, several investigations were conducted to take materials that were well characterized in the classical domain to determine if they could be utilized in what can be called the “quantum domain”. Of special interest were radiation effects on GaN nanowires1\,  flying qubit investigations2\, and tautomers which could be utilized in a variety of quantum circuits. The tautomer investigations were performed on cis- and trans-azobenzene and the proton tautomer croconic acid. Also of interest are the cyclopentadienyls Bis(cyclopentadienyl)cobalt(II) and  Bis(cyclopentadienyl)iron with properties that could make them good candidates for spintronic applications3. In this talk we will discuss some aspects of these investigations including our use of Density Functional Theory (DFT) tools4. \nNASA’s interest lies in how these materials could be used in systems for quantum communications\, computing or other useful applications. Most of this research was conducted by graduate students and faculty associated with our NASA internships. Additional parallel research paths included development of optical angular momentum (OAM) capabilities\, quantum entanglement\, optical neural networks5\, and quantum compressive sensing6. \n\nJacobs\, B.

SUMMARY:Koichiro Yawata (Institute of Science\, Tokyo)
DESCRIPTION:Title: Reduced-Order Control of Coupled Phase Oscillator Populations and Hypergraph-Based Approaches to Combinatorial Optimization Problems\n \nAbstract:  \nIn this seminar\, I will present two recent pieces of work from my research: one on reduced-order control of coupled oscillator populations and another on hypergraph-based approaches to combinatorial optimization. \n1. Reduced-Order Control of Coupled Oscillator Populations via Frequency-Dependent Forcing\nWe propose a frequency-dependent forcing framework for heterogeneous populations of coupled phase oscillators. Using the Ott-Antonsen ansatz\, we derive a low-dimensional description of the collective dynamics and study control methods for the macroscopic phase and synchronization level. \n2. Hypergraph Neural Networks Accelerate MUS Enumeration\nWe propose a hypergraph-neural-network-based method for accelerating MUS enumeration in constraint satisfaction problems. By combining hypergraph modeling with reinforcement learning\, the method reduces satisfiability checks and improves enumeration efficiency. \nThis seminar will take place in Room S08 at the Faculty of Sciences.
