Abstract:

There is a close relation between the color number of a continuous map $f\colon X \to X$ without fixed points and the topological dimension. If $f$ is an involution, the color number is also related to the co-index. An addition theorem for the color number is established thus underscoring the interrelations between color number, dimension and co-index.
