An approach to open and closed sets in ideal topological spaces

The first part of this thesis consists of the introduction part. In the introduction literature information about topological spaces and open and closed sets in ideal topological spaces is given. In the second chapter, the definition, and properties of ideal topological spaces and some generalized sets, which will be used in the next chapter, are given. In the third chapter, the properties of γ -open and γ -closed, γ -pre-open sets, γ -semi-open sets, and γ -b -open sets created with the help of a γ operation are mentioned. The fourth chapter was originally prepared. In this section, the sets defined with the help of the γ operation are transferred to ideal topological spaces.
