 S\n	\n	Abstract: Graphon has recently been introduced by Lovasz\, Sos\, etc.
  to study very large graphs. A graphon can be understood as either the lim
 it object of a convergent sequence of graphs\, or\, a statistical model fr
 om which to sample large random graphs. We take here the latter point of v
 iew and address the following problem: What is the probability that a rand
 om graph sampled from a graphon has a Hamiltonian decomposition? We have r
 ecently observed the following phenomenon: In the asymptotic regime where 
 the size of the random graph goes to infinity\, the probability tends to b
 e either 0 or 1\, depending on the underlying graphon. In this talk\, we e
 stablish this “zero-one” property for the class of step-graphons and provi
 de a geometric characterization.\n	\n	Bio: Xudong Chen is an Associate Profe
 ssor in the Department of Electrical and Systems Engineering at Washington
  University in St. Louis. He obtained the B.S. degree in Electronic Engine
 ering from Tsinghua University\, Beijing\, China\, in 2009\, and the Ph.D.
  degree in Electrical Engineering from Harvard University\, Cambridge\, Ma
 ssachusetts\, in 2014. He is an awardee of the 2020 Air Force Young Invest
 igator Program\, a recipient of the 2021 NSF Career Award\, the recipient 
 of the 2021 Donald P. Eckman Award\, and the recipient of the 2023 A.V. Ba
 lakrishnan Early Career Award. His current research interests are in the a
 rea of control theory\, stochastic processes\, optimization\, network scie
 nce\, and their applications.\n	\n	Link to Event\n
