Abstract:We introduce the notions of δ-I- open sets and semi δ-I-continuous functions in ideal topological spaces and investigate some of their properties. Additionally, we obtain decompositions of semi-I-continuous functions and α-I-continuous functions by using δ-I-open sets. This revised version was published online in June 2006 with corrections to the Cover Date.
Keywords:α  -I-continuous  semi-I-continuous  δ  -I-open
