In this paper we will study the main properties of the set solutions of the paratingent equation (type differential inclu sion) with delayed argument of the form: (Ptx)(t) ⊂ F((x)t) for t ≥ 0 with the initial condition: x(t) = ζ(t) for t ≤ 0. We will be interested particularly in the topological properties of emission and zone of emission.

On the structure of the set solutions of a class of paratingent equation with delayed argument
