摘要：In this paper, we study some properties of ultraconnected spaces and show that ultraconnected T12 spaces are maximal ultraconnected and minimal T12. We also introduce the notion of F-connected spaces, topological spaces wich are both hyperconnected and ultraconnected and characterize compact maximal F-connected topologies on a set.
