Segment Inequality and Almost Rigidity Structures for Integral Ricci Curvature [PDF]

International mathematics research notices, 2020
We will show the Cheeger–Colding segment inequality for manifolds with integral Ricci curvature bound. By using this segment inequality, the almost rigidity structure results for integral Ricci curvature will be derived by a similar method as in [1 ...

Some Inequalities on Finsler Manifolds with Weighted Ricci Curvature Bounded Below [PDF]

Results in Mathematics, 2021
We establish some important inequalities under a lower weighted Ricci curvature bound on Finsler manifolds. Firstly, we establish a relative volume comparison of Bishop–Gromov type.

Chen-Ricci Inequalities with a Quarter Symmetric Connection in Generalized Space Forms

Advances in Mathematical Physics, 2021
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 form and a Legendrian submanifold in a generalized Sasakian space form.

Chen–Ricci inequalities for submanifolds of Riemannian and Kaehlerian product manifolds

Annales Polonici Mathematici, 2016
Summary: Some examples of slant submanifolds of almost product Riemannian manifolds are presented. The existence of a useful orthonormal basis in proper slant submanifolds of a Riemannian product manifold is proved. The sectional curvature, the Ricci curvature and the scalar curvature of submanifolds of locally product manifolds of almost constant ...

A Qualitative Analysis of Social Indicators in Highly Polluting Sectors: The Challenge for Multifaceted Standards in Emerging Economies

Business Ethics, the Environment &Responsibility, Volume 35, Issue 3, Page 1931-1951, July 2026.
ABSTRACT The institutional current effort to regulate and increase the quantity and quality of sustainability information reported by companies is undeniable. However, the growing complexity of sustainability reporting standards creates isolated compartments for each major dimension of sustainability, leaving aside their interconnectedness and combined

Cohomogeneity‐one solitons in Laplacian flow: Local, smoothly‐closing and steady solitons

Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We initiate a systematic study of cohomogeneity‐one solitons in Bryant's Laplacian flow of closed G2$\text{G}_2$‐structures on a 7‐manifold, motivated by the problem of understanding finite‐time singularities of that flow. Here, we focus on solitons with symmetry groups Sp(2)${\rm Sp}(2)$ and SU(3)${\rm SU}(3)$; in both cases, we prove the ...

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

Communications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\
