Lightlike Hypersurfaces of Meta-Golden Semi-Riemannian Manifolds
Mathematics, 2023 In this research, we embark on the examination of lightlike hypersurfaces within an almost meta-Golden semi-Riemannian manifold. We investigate the properties of the induced structure on a lightlike hypersurface by meta-Golden semi-Riemannian structure ...

On Golden Lorentzian Manifolds Equipped with Generalized Symmetric Metric Connection
Mathematics, 2021 This research deals with the generalized symmetric metric U-connection defined on golden Lorentzian manifolds. We also derive sharp geometric inequalities that involve generalized normalized δ-Casorati curvatures for submanifolds of golden Lorentzian ...

Golden ratio in venation patterns of dragonfly wings
Scientific Reports, 2023 The vein pattern in insect wings allows this lightweight structure to carry multiple biological functions. Here, an investigation of the angular distribution of the vein struts in dragonfly wings revealed that the golden angle or golden ratio dominates ...
