Abstract

In this paper, we introduce and investigate partially antiinvariant submanifolds of Kenmotsu manifolds. The integrability of the involved distributions is examined, and conditions ensuring that the induced foliations are totally geodesic are obtained. We further explore the geometric properties of these distributions when the associated structure tensors N and P are parallel. By making use of the curvature tensor of Kenmotsu manifolds and the properties of Kenmotsu space forms with constant psi sectional curvature, we derive various geometric characterizations of partially anti-invariant submanifolds. In addition, we characterize totally umbilical partially anti-invariant submanifolds and establish an inequality for partially anti invariant submanifolds of Kenmotsu space forms, including the characterization of the equality case.
