We say that a pair of topological spaces (X, Y ) is good if for every A β X and every continuous f : A β Y there exists f : X β Y which extends f and is continuous at every point of A. We use this notion to characterize several classes of topological spaces, as hereditarily normal spaces, hereditari

In this paper we prove some properties of p -additive functions as well as p -additive set -valued functions. We start with some definitions. Definition 2.1. A set C β X (where X is a vector space) is said to be a convex cone if and only if C + C β C and t C β C for all t β (0, β). Definition 2.2.
