Topology of Rough Sets

  • Lech Polkowski
Part of the Advances in Soft Computing book series (AINSC, volume 15)


We consider here rough sets that arise in an information system from the point of view of topology. It will be our aim to introduce topologies into the realm of rough sets and investigate their properties. We will be guided by facts from general topological theory exposed in Chapter 7.
