Augmentations of Forman’s Ricci curvature and their applications in community detection
Journal of Physics: ComplexityThe notion of curvature on graphs has recently gained traction in the networks community, with the Ollivier–Ricci curvature (ORC) in particular being used for several tasks in network analysis, such as community detection.

On the Ricci Curvature of Normal-Metric Contact Pair Manifolds
Journal of New Theory, 2021 In this study, we work on normal-metric contact pair manifolds under certain conditions related to the Ricci curvature. We obtain some results for generalized quasi-Einstein normal-metric contact pair manifolds.

, 2013 We study minimal hypersurfaces in manifolds of non-negative Ricci curvature, Euclidean volume growth and quadratic curvature decay at infinity. By comparison with capped spherical cones, we identify a precise borderline for the Ricci curvature decay ...

Clifford representatives via the uniform algebraic rank
Journal of the London Mathematical Society, Volume 111, Issue 6, June 2025.Abstract In this paper, we introduce the uniform algebraic rank of a divisor class on a finite graph. We show that it lies between Caporaso's algebraic rank and the combinatorial rank of Baker and Norine. We prove the Riemann–Roch theorem for the uniform algebraic rank, and show that both the algebraic and the uniform algebraic rank are realized on ...

On the equivalence of two curvature conditions for Lorentzian hypersurfaces
Arab Journal of Mathematical Sciences, 2017 Let n≥3. We show that semi-symmetry and Ricci-semisymmetry conditions are equivalent for any n-dimensional Lorentzian hypersurface in a Lorentzian space form with nonzero curvature.

European Journal of Organic Chemistry, Volume 28, Issue 20, May 28, 2025.New amphiphilic fluoro‐functionalized cellulosic materials are being yielded through nucleophilic aromatic substitution. Covalent attachment of fluorinated moiety into biopolymers is being assured with full characterization. Fluoro‐functionalized materials are being incorporated in alginate beads to remove organic pollutants from wastewater ...
