L-optimal transportation for Ricci flow [PDF]

open access: yes, 2009
We introduce the notion of L-optimal transportation, and use it to construct a natural monotonic quantity for Ricci flow which includes a selection of other monotonicity results, including some key discoveries of Perelman [13] (both related to entropy ...

Curvature Invariants for Statistical Submanifolds of Hessian Manifolds of Constant Hessian Curvature

open access: yesMathematics, 2018
We consider statistical submanifolds of Hessian manifolds of constant Hessian curvature. For such submanifolds we establish a Euler inequality and a Chen-Ricci inequality with respect to a sectional curvature of the ambient Hessian manifold.

Applications of differential equations to characterize the base of warped product submanifolds of cosymplectic space forms

open access: yesJournal of Inequalities and Applications, 2020
In the present, we first obtain Chen–Ricci inequality for C-totally real warped product submanifolds in cosymplectic space forms. Then, we focus on characterizing spheres and Euclidean spaces, by using the Bochner formula and a second-order ordinary ...

Ricci flow coupled with harmonic map flow [PDF]

open access: yes, 2012
07.02.13 KB. Accepted version ok to add to Spiral. SMF/SherpaWe investigate a new geometric flow which consists of a coupled system of the Ricci flow on a closed manifold M with the harmonic map flow of a map phi from M to some closed target manifold N ...

The stability inequality for Ricci-flat cones [PDF]

open access: yes, 2014
In this article, we thoroughly investigate the stability inequality for Ricci-flat cones. Perhaps most importantly, we prove that the Ricci-flat cone over CP^2 is stable, showing that the first stable non-flat Ricci-flat cone occurs in the smallest ...

The volume entropy of a surface decreases along the Ricci flow [PDF]

open access: yes, 2004
The volume entropy, h(g), of a compact Riemannian manifold (M,g) measures the growth rate of the volume of a ball of radius R in its universal cover.

Recent Developments on the First Chen Inequality in Differential Geometry

open access: yes, 2023
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 submanifolds and find their applications.

Ricci curvature inequalities for warped product skew CR-submanifolds in Cosymplectic space forms

open access: yes, 2021
<p>The main objective of this paper is to achieve the Chen-Ricci inequality for skew CR-warped product submanifold isometrically immersed in a Cosymplectic space form in the expressions of the squared norm of mean curvature vector and warping ...

The Log-Sobolev inequality for a submanifold in manifolds with asymptotic non-negative intermediate Ricci curvature [PDF]

open access: yes, 2023
We prove a sharp Log-Sobolev inequality for submanifolds of a complete non-compact Riemannian manifold with asymptotic non-negative intermediate Ricci curvature and Euclidean volume growth.

Statistical Solitons and Inequalities for Statistical Warped Product Submanifolds

open access: yesMathematics, 2019
Warped products play crucial roles in differential geometry, as well as in mathematical physics, especially in general relativity. In this article, first we define and study statistical solitons on Ricci-symmetric statistical warped products R ×
