DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CRM-CAMP/34/
 ">Computer assisted existence proof of complicated dynamics in forced dela
 y action oscillator modelling El Nino phenomena</a>\nby Shin'ichi Oishi (W
 aseda University\, Japan) as part of CRM CAMP (Computer-Assisted Mathemati
 cal Proofs) in Nonlinear Analysis\n\n\nAbstract\nA computer assisted proof
  is presented for the existence of various periodic solutions for forced S
 uarez-Schopf's equation\, which are delay differential equations modeling 
 El Nino. Tight inclusions of periodic solutions are calculated through num
 erical verification method by utilizing a structure of Galerkin's equation
  for forced Suarez-Schopf's equation effectively. The existence of various
  periodic solutions has been proved via computer assisted proofs including
  various subharmonics. Especially\, coexistence of several subharmonics ar
 e proved and numerical simulations are presented suggesting an appearance 
 of chaos.\n
