Improved Chen’s Inequalities for Submanifolds of Generalized Sasakian-Space-Forms
In this article, we derive Chen’s inequalities involving Chen’s δ-invariant δM, Riemannian invariant δ(m1,⋯,mk), Ricci curvature, Riemannian invariant Θk(2≤k≤m), the scalar curvature and the squared of the mean curvature for submanifolds of generalized ...

Chen’s first inequality for statistical submanifolds in Hessian manifolds of constant Hessian curvature was obtained by B.-Y. Chen et al. Other particular cases of Chen inequalities in a statistical setting were given by different authors.

In this paper, we prove some inequalities between intrinsic and extrinsic curvature invariants, namely involving the Chen first invariant and the mean curvature of totally real and holomorphic spacelike submanifolds in statistical manifolds of type para ...

Chen-Ricci Inequalities with a Quarter Symmetric Connection in Generalized Space Forms
In this article, we obtain improved Chen-Ricci inequalities for submanifolds of generalized space forms with quarter-symmetric metric connection, with the help of which we completely characterized the Lagrangian submanifold in generalized complex space ...

Chen Inequalities for Statistical Submanifolds of Kähler-Like Statistical Manifolds [PDF]
We consider Kähler-like statistical manifolds, whose curvature tensor field satisfies a natural condition. For their statistical submanifolds, we prove a Chen first inequality and a Chen inequality for the invariant δ ( 2 , 2 ) .

Chen optimal inequalities of CR-warped products of generalized Sasakian space form
Our main objective of this paper is to derive the relationship between the main extrinsic invariant, and the contact CR δ-invariant (new intrinsic invariant) on a generic submanifold in trans-Sasakian generalized Sasakian space forms.

Chen’s Ricci inequalities and topological obstructions on null hypersurfaces of a Lorentzian manifold [PDF]
Given a null hypersurface of a Lorentzian manifold, we isometrically immerse a null hypersurface equipped with the Riemannian metric (induced on it by the rigging) into a Riemannian manifold suitably constructed on the Lorentzian manifold.

B.-Y. CHEN INEQUALITIES FOR SUBMANIFOLDS IN GENERALIZED COMPLEX SPACE FORMS [PDF]
Some relationships between intrinsic and extrinsic invariants of submanifolds in generalized space forms are studied. They are established for slant, totally real and invariant submanifolds in generalized complex space forms, complex space forms and RK-manifolds.

Β. Y. CHEN INEQUALITIES FOR SLANT SUBMANIFOLDS IN COMPLEX SPACE FORMS
The reviewer introduces in [Japan. J. Math. 26, No. 1, 105-127 (2000)] a string of new Riemannian invariants, denoted by \(\delta(n_1,\ldots,n_k)\), and establishes sharp inequalities between the invariants and the squared mean curvature for an arbitrary submanifold in a real space form.
