Some generalized continuity types defined by generalized open sets

This study consists of five chapters. In first chapter, it was given the background knowledge and necessary concepts. We summarized some basic information concerning generalized topology which we will study on it. In the second chapter, we defined contra-(θ_μ,λ)-continuity and almost contra-(θ_μ,λ)-continuity. In this chapter we gave the characterization of contra-(θ_μ,λ)-continuity. We also examined the relationship between contra-(θ_μ,λ)-continuity and almost contra-(θ_μ,λ)-continuity and between some types of continuity. In the third chapter, we gave characterization of almost contra-(θ_μ,λ)-continuity and we got some results. In the fourth chapter, we defined almost contra-(θ_(μ_1,μ_2 ), δ_(ν_1,ν_2 ))-continuity and we gave the characterization. We also examined the relationship between some types of continuity and we got some results. In the fifth chapter, we stated the results.
