Sequentially contents on topological spaces

This thesis consists of four chapters. In the first chapter, the aim of the thesis is explained and the literatüre review is given. In the second chapter, the notions of Hausdorff space, continuity, sequentially convergence, which will be used on the following pages are given. In the third chapter, the notions of sequentially open and sequentially closed sets in a topological space are discussed. Finally, the fourth chapter is prepared originally. Sequentially Hausdorff spaces are introduced by sequentially open sets and the relationships between Hausdorff spaces and sequentially Hausdorff spaces are discussed. Additinally, the notion of full sequentially Hausdorff spaces are given and examplified
