TLDR
In this article, Ricci symmetric almost Kenmotsu manifolds were characterized under several constraints and proved that they are Einstein manifolds, and several corollaries were obtained.Abstract:
In the present paper, we characterize Ricci symmetric almost Kenmotsu manifolds under several constraints and proved that they are Einstein manifolds As a consequence, we obtain several corollaries Finally, an illustrative example is presented to verify our resultsread more

A class of almost contact riemannian manifolds
TL;DR: In this article, Tanno has classified connected almost contact Riemannian manifolds whose automorphism groups have themaximum dimension into three classes: (1) homogeneous normal contact manifolds with constant 0-holomorphic sec-tional curvature if the sectional curvature for 2-planes which contain

TL;DR: In this paper, the authors consider locally symmetric almost Kenmotsu manifold and show that the manifold is locally isometric to the Riemannian product of an n+1-dimensional manifold of constant curvature.
