One of the most fundamental interests in submanifold theory is to establish simple
relationships between the main extrinsic invariants and the main intrinsic invariants of …

In this paper, we introduce point-wise slant submanifolds of almost contact and almost
contact 3-structure manifolds. We characterize them, give some examples, and obtain …

We improve Chen-Ricci inequalities for a Lagrangian submanifold Mn of dimension n (n⩾ 2)
in a 2n-dimensional complex space form M2n (4c) of constant holomorphic sectional …

We studied isometric immersions into an almost contact metric manifold which falls in the
Chinea–Gonzalez class C_5 ⊕ C_ 12 C 5⊕ C 12, under the hypothesis that the Reeb …

It is well known that a dynamical system is a concept in mathematics where a fixed rule
describes how a point in a geometrical space depends on time. A mathematical model is a …

In this paper, some equalities and inequalities involving the Riemannian curvature
invariants are obtained on 3-semi slant submanifolds of cosymplectic 3-space forms …

In this study, we concluded the Hamiltonian equations on (ℳ9, λ, XH), being a model. Finally
introduce, some geometrical and physical results on the related mechanic systems have …

Abstract‎ In this paper‎,‎ we study hemi-slant submanifolds of 3-Sasakian manifolds‎.‎ First‎,‎ we
obtain some new results in terms of the operators $ T_i $ and $ n_i $ and then by using …

Contact geometry is the odd-dimensional analogue of symplectic geometry with certain
manifolds of odd dimension. It is close to symplectic geometry and like the latter it originated …
