SUMMARY:Junior Dynamics Seminar – Masood Ahmad
DESCRIPTION:Observable Lyapunov Exponents for Globally Coupled Maps in the 
 Mean-Field Limit\nSpeaker: Masood Ahmad\nAbstract: Large coupled systems c
 an exhibit microscopic chaos alongside stable macroscopic behaviour. We in
 troduce observable Lyapunov exponents to quantify this distinction. For gl
 obally coupled maps\, we show that these exponents are determined by the l
 inearisation of the self-consistent transfer operator. Applying this resul
 t to weakly coupled uniformly expanding maps\, we prove that macroscopic p
 erturbations decay near a stationary mean-field state\, despite microscopi
 c chaos. Our findings provide a rigorous framework for distinguishing micr
 oscopic and macroscopic chaos.\n
