On Gauss-Bonnet Curvatures [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2007 The $(2k)$-th Gauss-Bonnet curvature is a generalization to higher dimensions of the $(2k)$-dimensional Gauss-Bonnet integrand, it coincides with the usual scalar curvature for $k = 1$.

Curvatures of smectic liquid crystals and their applications
Journal of Information Display, 2018 Curvature is an important concept for understanding layering structures in soft matters, ranging from complex macromolecular self-assembled structures to simple lipid bilayers.

Unified theory of the anomalous and topological Hall effects with phase-space Berry curvatures [PDF]
Science Advances, 2022 Spontaneously broken time-reversal symmetry in magnetic materials leads to a Hall response, with a nonzero voltage transverse to an applied current, even in the absence of external magnetic fields.

Geometrical Structure in a Relativistic Thermodynamical Fluid Spacetime
Axioms, 2023 The goal of the present research paper is to study how a spacetime manifold evolves when thermal flux, thermal energy density and thermal stress are involved; such spacetime is called a thermodynamical fluid spacetime (TFS). We deal with some geometrical

Gradient Origami Metamaterials for Programming Out‐of‐Plane Curvatures
Advanced Engineering Materials, 2023 Origami structures are a traditional Japanese art that have recently found their way into engineering applications due to their powerful capability to transform flat 2D structures into complex 3D structures along their creases.

Normal Curves in 4-Dimensional Galilean Space G4
Frontiers in Physics, 2021 In this article, first, we give the definition of normal curves in 4-dimensional Galilean space G4. Second, we state the necessary condition for a curve of curvatures τ(s) and σ(s) to be a normal curve in 4-dimensional Galilean space G4. Finally, we give

Nonpositivity: Curvature vs. curvature operator [PDF]
Proceedings of the American Mathematical Society, 2004 It is shown that there exist closed Riemannian manifolds M M all of whose sectional curvatures are negative, but M M does not admit any metric with nonpositive curvature operator.

Graph Ricci curvatures reveal atypical functional connectivity in autism spectrum disorder
Scientific Reports, 2022 While standard graph-theoretic measures have been widely used to characterize atypical resting-state functional connectivity in autism spectrum disorder (ASD), geometry-inspired network measures have not been applied. In this study, we apply Forman–Ricci
