The properties of zeros for a class of exponential polynomials and applications in economical systems (Q2784705)

The authors consider differential-difference equations with exponential terms. For stability consideration, the authors establish a theorem on necessary and sufficient conditions under which all zeros of the characteristic equations lie on the left of the imaginary axis. This work contributes to the study of coupled oscillators with time-delay coupling (neural oscillators). It is also applicable to economical models with time-delay relationships like the Kalecki macro-dynamical models of business cycles.NEWLINENEWLINEFor the entire collection see [Zbl 0971.00016].
