Property related to denseness
Posted:
Jan 12, 2013 6:41 PM


Let A be a subset of the topological space of X. What is the standard terminology for the property that X = the intersection of all the open sets that contain A? This seems related to A being dense in X but it is clearly not the same. Is this a stronger property than denseness? Where does this property stand in relation to denseness?
Thank you,
Paul Epstein
