On the volume measure of non-smooth spaces with Ricci curvature bounded below [PDF]
, 2016 We prove that, given an $RCD^{*}(K,N)$-space $(X,d,m)$, then it is possible to $m$-essentially cover $X$ by measurable subsets $(R_{i})_{i\in \mathbb{N}}$ with the following property: for each $i$ there exists $k_{i} \in \mathbb{N}\cap [1,N]$ such that ...

Ricci curvature bounds for weakly interacting Markov chains [PDF]
, 2016 We establish a general perturbative method to prove entropic Ricci curvature bounds for interacting stochastic particle systems. We apply this method to obtain curvature bounds in several examples, namely: Glauber dynamics for a class of spin systems ...

Expanding Ricci solitons with pinched Ricci curvature
Kodai Mathematical Journal, 2011 In this paper, we prove that expanding gradient Ricci solitons with (positively) pinched Ricci curvature are trivial ones. Namely, they are either compact or flat.

Hyperbolic Gradient-Bourgoignon Flow
پژوهشهای ریاضی, 2022 Introduction Ricci solitons as a generalization of Einstein manifolds introduced by Hamilton in mid 1980s. In the last two decades, a lot of researchers have been done on Ricci solitons.

American Journal of Hematology, Volume 100, Issue 7, Page 1196-1204, July 2025.ABSTRACT Discordant results have been generated regarding the prognostic role of Total Metabolic Tumor Volume (TMTV) in Follicular Lymphoma (FL). The use of prospective data and the adoption of the newly defined standardized SUV4 method for calculating TMTV may generate stronger evidence.

η-Ricci Solitons on Kenmotsu 3-Manifolds
Annals of the West University of Timisoara: Mathematics and Computer Science, 2018 In the present paper we study η-Ricci solitons on Kenmotsu 3-manifolds. Moreover, we consider η-Ricci solitons on Kenmotsu 3-manifolds with Codazzi type of Ricci tensor and cyclic parallel Ricci tensor.

British Journal of Pharmacology, Volume 182, Issue 13, Page 2997-3016, July 2025.Abstract Background and Purpose Preclinical studies suggest that highly selective dopamine D3 receptor (D3R) antagonists or partial agonists hold promise for treating substance use disorders. However, their limited effectiveness in reducing cocaine self‐administration is a major drawback.

On the Ricci curvature of steady gradient Ricci solitons
Journal of Mathematical Analysis and Applications, 2010 AbstractAssume (Mn,g) is a complete steady gradient Ricci soliton with positive Ricci curvature. If the scalar curvature approaches 0 towards infinity, we prove that ∫0+∞Rc(γ˙(s),γ˙(s))ds=R(O), where O is the point where R obtains its maximum and γ(s) is a minimal normal geodesic emanating from O.

On the equivalence of generalized Ricci curvatures
Proceedings of the American Mathematical SocietyWe prove the equivalence between the several notions of generalized Ricci curvature found in the literature. As an application, we characterize when the total generalized Ricci tensor is symmetric.
