Abstract:
We study the dynamics of the generalized Mackey–Glass equation with two
delays using the large-parameter method. After a special exponential
replacement of variables, a singularly perturbed equation is obtained, for
which we construct a meaningful limit object, a differential–difference
relay equation with two delays. We prove that the relay equation has a simple periodic solution with one interval on the period where the solution is positive. To illustrate the obtained result, we numerically analyze the original singularly perturbed equation, for which we find a solution near the periodic solution of the limit relay equation.
