Abstract
In this paper by using the ring of real-valued continuous functions , we prove a theorem in profinite spaces which states that for a compact Hausdorff space , the set of its connected components endowed with some topology is a profinite space. Then we apply this result to give an alternative proof to the fact that the category of profinite spaces is a reflective subcategory in the category of compact Hausdorff spaces. Finally, under some circumstances on a space , we compute the connected components of the space in terms of the ones of the space .
