Abstract: To equip a space with a structure leads to the production of a new mathematical object and consequently to contribute to the development of science. Manifolds equipped with certain differential-geometric structures are richer and more practical spaces, they have been studied widely in differential geometry. Indeed, D. Chinea and C. Gonzalez \cite{CG} obtained a classification of the (2n + 1)-dimensional almost contact metric manifold based on $U(n) × I$ representation theory, which is an analogy of the classification of the $2n$-dimensional almost Hermitian manifolds established by A. Gray ...
