Homotopies and the Universal Fixed Point Property

A topological space is said to have the fixed point property if every continuous self-map of it has at least one fixed point. In this text, we investigate the additional restraints imposed by the requirement that a fixed point can be chosen continuously when the self-map is varied continuously. While we are able to present a class of universal fixed point spaces, where this is always possible, we also show that many common fixed point spaces are not universal.
