IAS Seminar: How Do Interacting Agents Self-Organize into a Coherent Mono-Kinetic State?
Guest Lecturer: Professor Eitan Tadmor, USA
How do interacting agents — whether birds flocking, robots coordinating, or particles aligning — self-organize into a coherent mono-kinetic state?
The Institute of Advanced Studies invites you to the lecture by Professor Eitan Tadmor, Department of Mathematics and the Institute for Physical Science and Technology, University of Maryland.
Professor Tadmor is visiting Tel Aviv University as part of the Lowy Distinguished Guest Professors series 2025–2026.
As part of the Seminar in Applied Mathematics, Professor Tadmor will deliver a lecture on the Emergence of Mono-Kinetic Solutions for Euler Alignment Equations. He will examine the emergent behavior of agent-based systems driven by alignment, discussing hydrodynamic models leading to the Euler alignment system, the mathematical challenge of closure due to missing energy balance, and the role of a reversed entropy inequality in selecting mono-kinetic states.
The lecture will present recent results establishing strong solutions in dimensions D > 2, resolving a long-standing open problem in collective dynamics.
When: January 7, 2026 | 12:00 pm
Where: Schreiber Building, Room 309
Light refreshments will be served before the lecture.
The lecture will be conducted in English and is open to the public.
