CSI-ξ^⊥-Riemannian maps from Kenmotsu manifolds to Riemannian manifolds

Abstract

In this article, we take into account a new class of semi-invariant ξ^⊥-Riemannian maps, namely, CSI-ξ^⊥ (Clairaut semi-invariant-ξ^⊥)-Riemannian maps in contact geometry and discuss CSI-ξ^⊥-Riemannian maps from Kenmotsu manifolds to Riemannian manifolds. We extend the notion of semi-invariant ξ^⊥-Riemannian maps to CSI-ξ^⊥-Riemannian maps and obtain a necessary and sufficient condition for this extension. We also investigate some geometric properties of these maps and exhibit a non-trivial example of discussed maps.
