Almost Non-negative Scalar Curvature on Riemannian Manifolds Conformal to Tori [PDF]

open access: yesJournal of Geometric Analysis, 2020
In this article we reduce the geometric stability conjecture for the scalar torus rigidity theorem to the conformal case via the Yamabe problem. Then we are able to prove the case where a sequence of Riemannian manifolds is conformal to a uniformly ...

Tensor invariants of generalized Kenmotsu manifolds [PDF]

open access: yesE3S Web of Conferences, 2021
In this paper, we study the properties of generalized Kenmotsu manifolds, consider the second-order differential geometric invariants of the Riemannian curvature tensor of generalized Kenmotsu manifolds (by the symmetry properties of the Riemannian ...

A remark on the metric dimension in Riemannian manifolds of constant curvature [PDF]

open access: yesAUT Journal of Mathematics and Computing
We compute the metric dimension of Riemannian manifolds of constant curvature. We define the edge weghited metric dimension of the geodesic graphs in Riemannian manifolds and we show that each complete geodesic graph $G=(V,E)$ embedded in a Riemannian ...

A Contribution of Liouville-Type Theorems to the Geometry in the Large of Hadamard Manifolds

open access: yesMathematics, 2022
A complete, simply connected Riemannian manifold of nonpositive sectional curvature is called a Hadamard manifold. In this article, we prove Liouville-type theorems for isometric and harmonic self-diffeomorphisms of Hadamard manifolds, as well as ...

Functions with bounded variation on a class of Riemannian manifolds with Ricci curvature unbounded from below [PDF]

open access: yes, 2012
After establishing some new global facts (like a measure theoretic structure theorem and a new invariant characterization of Sobolev functions) about complex-valued functions with bounded variation on arbitrary noncompact Riemannian manifolds, we extend ...

Growth of finitely generated solvable groups and curvature of Riemannian manifolds

open access: yes, 1968
If a group Γ is generated by a finite subset 5, then one has the "growth function" gs, where gs(m) is the number of distinct elements of Γ expressible as words of length

Curvature of K-contact Semi-Riemannian Manifolds

open access: yesCanadian mathematical bulletin, 2014
. In this paper we characterize $K$ -contact semi-Riemannian manifolds and Sasakian semi-Riemannian manifolds in terms of curvature. Moreover, we show that any conformally flat $K$ -contact semi-Riemannian manifold is Sasakian and of constant sectional ...

On generalized semisymmetric Riemannian manifolds

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2013
There are several generalizations of the concept of semi-symmetric Riemannian manifolds. In the present paper, we consider some special types of generalized semi-symmetric Riemannian manifolds with positive or negative defined curvature operator or ...

Emergent time, cosmological constant and boundary dimension at infinity in combinatorial quantum gravity

open access: yesJournal of High Energy Physics, 2022
Combinatorial quantum gravity is governed by a discrete Einstein-Hilbert action formulated on an ensemble of random graphs. There is strong evidence for a second-order quantum phase transition separating a random phase at strong coupling from an ordered,
