• On periodic solutions and global dynamics in a periodic differential delay equation 

      [OWP-2014-08] Ivanov, Anatoli F.; Trofimchuk, Sergei I. (Mathematisches Forschungsinstitut Oberwolfach, 2014-05-13)
      Several aspects of global dynamics and the existence of periodic solutions are studied for the scalar differential delay equation x(t)=a(t)f(x([tK])), where f(x) is a continuous negative feedback function, $x \cdot ...
    • Square wave periodic solutions of a differential delay equation 

      [OWP-2014-09] Ivanov, Anatoli F.; Verriest, Erik I. (Mathematisches Forschungsinstitut Oberwolfach, 2014-05-13)
      We prove the existence of periodic solutions of the differential delay equation ε˙x(t)+x(t)=f(x(t1)),ε>0 under the assumptions that the continuous nonlinearity f(x) satisfies the negative ...
