In symbols, a finite set S with n elements contains 2 n subsets, so that the cardinality of the set S is n and its power set P(S) is 2 n.
In this paper we consider a suitable definition of convergence and introduce star closed sets that enable us to establish a variant of Cantor intersection theorem as well as Baire category .

Eugene Boman and Robert Rogers. Does the converse also hold? And if not, what is a suitable counterexample for the same? Also, if the converse does not hold, does the Cantor's Intersection Theorem hold only for complete metric spaces, or does it hold for more general spaces too? In this way one obtains infinitely many distinct cardinal .

This is the Wikipedia proof of Cantor's intersection theorem: $C_0\supseteq C_1\supseteq C_2.In this case, Cantor’s intersection theorem for K-metric spaces can be for-mulated as its classical version. In this manuscript we give an affirmative answer to this open question.While this is clear for finite sets, no one had seriously considered .Many people believe that the result known as Cantor’s theorem says that the real numbers, R, have a greater cardinality than the natural numbers, N.
