초록
In Cho et al. (Results Math 77(3):16, 2022), the authors defined the notion of the weakly eta-Einstein structure on almost contact metric manifolds. In this paper, we investigate some classes of three-dimensional almost contact metric manifolds with weakly eta-Einstein structures. In particular, we classify the contact metric manifold, the almost cosymplectic manifold and the almost Kenmotsu manifold.
