Abstract
We show that for a partial action with closed domain of a compact group on a profinite space the space of orbits is profinite, this leads to the fact that when is profinite the enveloping space is also profinite. Moreover, we provide conditions for the induced quotient map of to have a continuous section. Relations between continuous sections of and continuous sections of the quotient map induced by the enveloping action of are also considered. At the end of this work we prove that the category of actions on profinite spaces with countable number of clopen sets is reflective in the category of actions of compact Hausdorff spaces having countable number of clopen sets.
