Abstract

top
In this article we define the m -topology on some rings of quotients of C ( X ) . Using this, we equip the classical ring of quotients q ( X ) of C ( X ) with the m -topology and we show that C ( X ) with the r -topology is in fact a subspace of q ( X ) with the m -topology. Characterization of the components of rings of quotients of C ( X ) is given and using this, it turns out that q ( X ) with the m -topology is connected if and only if X is a pseudocompact almost P -space, if and only if C ( X ) with r -topology is connected. We also observe that the maximal ring of quotients Q ( X ) of C ( X ) with the m -topology is connected if and only if X is finite. Finally for each point x , we introduce a natural ring of quotients of C ( X ) / O x which is connected with the m -topology.
