Almost Hermitian submersion

This study, presented as a master sciencethesis, consists of five chapter. The first chapter is the introduction and this chapter mentions previous work in the subject. In the second chapter, the basic concepts, Riemannian manifolds and complex manifolds that will be used in the other chapters throughout the sciencethesis are given. In the third chapter, Riemannian submersion geometry is presented, firstly T and A tensors defined by O'Neill are introduced and their general properties, geometric meanings and covariant derivatives of these tensors are examined. In the fourth chapter, the Hermitian manifold and its almost Hermitian and submanifolds are examined. Then, the relationship of almost Hermitian submersions with the basic tensors of Riemannian submersions was studied.
