Functional differential equations of advanced type with piecewise constant argument deviations are studied. They are closely related to impulse, loaded and, especially, to difference equations, and have the structure of continuous dynamical systems within intervals of unit length.
The aim of education is to provide the basis for life long learning and improvement.

To examine this issue, we revisit the jobs–housing balance, a pop...
