Hemi-slant ξ^⊥ Riemann submersions from Kenmotsu manifolds to Riemann manifolds

In this thesis, hemi-slant ξ^⊥-Riemann submersions from Kenmotsu manifolds to Riemannian manifolds are defined, and their geometric properties are examined. In the first chapter, a literature review is provided, and previous studies related to the topic of the thesis are introduced. In the second chapter, basic concepts related to Riemannian manifolds, Kenmotsu manifolds, and their submanifolds are discussed. In the third chapter, the definition, theorems, and examples of hemi-slant -Riemann submersions from Kenmotsu manifolds to Riemannian manifolds are presented. In the fourth chapter, the geometric properties of the distributions arising from the definition of a hemi-slant -Riemann submersion are investigated.
