SUMMARY:Seminaire de Chiara Cicolani
DESCRIPTION:- Title: Time-delayed opinion dynamics with leader-follower int
 eractions: consensus\, stability\, and mean-field limits\n\n- Abstract: We
  study a time-delayed variant of the Hegselmann-Krause opinion formation m
 odel featuring a small group of leaders and a large group of non-leaders. 
 In this model\, leaders influence all agents but only interact among thems
 elves. At the same time\, non-leaders update their opinions via interactio
 ns with their peers and the leaders\, with time delays accounting for comm
 unication and decision-making lags. We prove the exponential convergence t
 o consensus of the particle system\, without imposing smallness assumption
 s on the delay parameters. Furthermore\, we analyze the mean-field limit i
 n two regimes: (i) with a fixed number of leaders and an infinite number o
 f non-leaders\, and (ii) with both populations tending to infinity\, obtai
 ning existence\, uniqueness\, and exponential decay estimates for the corr
 esponding macroscopic models.\n\n- Bio:  Chiara Cicolani is a PhD student
  in Mathematics at the University of L’Aquila\, Italy. She completed he
 r studies at the University of L'Aquila with a Bachelor's degree in Math
 ematics and a master's degree in Mathematical modeling. Her research focu
 ses on applied mathematics\, with particular interests in control theory\,
  multi-agent systems\, and mathematical models in epidemiology and biology
 . She has collaborated with international research centers such as the Bas
 que Center for Applied Mathematics (BCAM) in Spain and Yonsei University i
 n Seoul\, and has presented her work at various international conferences 
 and workshops.\n\n- Lien teams :\nhttps://teams.microsoft.com/l/meetup-joi
