Abstract: This paper concerns an index theory for $\Bbb Z$-actions induced by a homeomorphism of a compact space. We give a definition of a genus for uniform spaces and prove that the genus for compact spaces is an index. To this end we show a ${\Bbb Z}$-version of the Borsuk-Ulam theorem and the existence of a continuous equivariant extension for these $\Bbb Z$-actions.
