title: Subcritical Hopf bifurcation in dynamical systems described by a scalar nonlinear delay differential equation.
abstract: A subcritical Hopf bifurcation in a dynamical system modeled by a scalar nonlinear delay differential equation is studied theoretically and experimentally. The subcritical Hopf bifurcation leads to a significant domain of bistability where stable steady and time-periodic states coexist.
