About This Event

Masood Ahmad will speak at the Junior Dynamics Seminar on 5 November 2026 at the Huxley Building, focusing on observable Lyapunov exponents for globally coupled maps in the mean-field limit. The seminar will explore the relationship between microscopic chaos and stable macroscopic behaviour.

Observable Lyapunov Exponents for Globally Coupled Maps in the Mean-Field Limit Speaker: Masood Ahmad Abstract : Large coupled systems can exhibit microscopic chaos alongside stable macroscopic behaviour. We introduce observable Lyapunov exponents to quantify this distinction. For globally coupled maps, we show that these exponents are determined by the linearisation of the self-consistent transfer operator. Applying this result to weakly coupled uniformly expanding maps, we prove that macroscopic perturbations decay near a stationary mean-field state, despite microscopic chaos. Our findings provide a rigorous framework for distinguishing microscopic and macroscopic chaos.
