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

In this paper we will study the main properties of the set solutions of the paratingent equation (type di¤erential inclusion) with delayed argument of the form: (Pt x)(t) ? F([x]t) for t > 0 with the initial condition: x(t) = ?(t) for t < 0. We will be interested particularly in the topological properties of emission and zone of emission.
