Selections and order-like relations
Keywords:Hyperspaces topology, Selection, Monotone selection, Ordered space
Every selection f for the family F2(X) of at most two-point subsets of a set X naturally defines an order-like relation on X by if and only . In the present paper we study the relationship between and the possible topologies T on X which realize the continuity of f with respect to the Vietoris topology on F2(X) generated by T.
