DESCRIPTION:ISS Informal Systems Seminar\n\n\n	Speaker: Chuang Xu – Universi
 ty of Hawaiʻi at Mānoa\, United States \n\n\n \n\n \n\n\n	\n\n	Presentation 
 on YouTube.\n\n	Abstract: Many science phenomena are described as interacti
 ng particle systems (IPS). The mean field limit (MFL) of large all-to-all 
 coupled deterministic IPS is given by the solution of a PDE\, the Vlasov E
 quation. Yet\, many applications demand IPS coupled on networks/graphs\, w
 hich are mostly heterogeneous. It is interesting to know\, how the limit o
 f a sequence of digraphs associated with the IPS influences the macroscopi
 c MFL. In this talk\, I will briefly introduce our recent work on Vlasov e
 quations on a generalized digraph\, regarded as the limit of a sequence of
  digraphs\, which we refer to as a digraph measure (DGM).Such DGM is a nat
 ural extension of graphon\, the limit of a sequence of dense graphs. It is
  noteworthy that DGM can be regarded as a limit of a sequence of digraphs 
 of different densities (dense\, sparse\, or of intermediate densities). I 
 will make some comparison between some recent results on MFL of IPS on gra
 ph limits and our contribution. Finally\, I will talk about some applicati
 ons of our results. This is a joint work with Prof. Christian Kuehn at the
  Technical University of Munich.\n\n	\n	Biography: Chuang Xu is an assistant
  professor in the Department of Mathematics at the University of Hawaiʻi a
 t Mānoa (UHM). Before joining UHM\, he was an Alexander von Humboldt postd
 oc fellow and Technical University Foundation Fellow (TUFF) at the Technic
 al University of Munich. Before that\, he was a postdoc in the MBIO group 
 at the University of Copenhagen. He received his PhD in Applied Mathematic
 s from the University of Alberta in 2018. His research interests are (1) a
 pproximation of measures\, (2) chemical reaction network theory\, (3) mean
  field theory of interacting particle systems on networks.\n\n
