Abstract: | First, we introduce the notion of f I-sets and investigate their properties in ideal topological spaces. Then, we also introduce the notions of R I C-continuous, f I-continuous and contra*-continuous functions and we show that a function f: (X,τ,I) to (Y,φ) is R I C -continuous if and only if it is f I-continuous and contra*-continuous. This revised version was published online in June 2006 with corrections to the Cover Date. |
