Totally Umbilical Hypersurfaces of Lorentzian Reducible Spaces

open access: yesJournal of Geometric Analysis
Abstract We investigate totally umbilical hypersurfaces in Lorentzian reducible spaces, focusing on their classification and geometric properties. We explore conditions for the existence of proper totally umbilical hypersurfaces in a $$(n+1)$$ (

Conformal Slant Riemannian Maps with Totally Umbilical Fibers

Mediterranean Journal of Mathematics, 2022
Riemannian maps between Riemannian manifolds were introduced by \textit{A. E. Fischer} [Contemp. Math. 132, 331--366 (1992; Zbl 0780.53033)] to generalise Riemannian submersions and isometric immersions. In this paper the authors use standard Riemannian geometry techniques to study conformal slant Riemannian maps and umbilical conformal slant ...

Conformal Killing Forms on Totally Umbilical Submanifolds

Journal of Mathematical Sciences, 2016
For a \(C^{\infty}\)-manifold \(M\) with a pseudo-Riemannian metric \(g\) and Levi-Civita connection \(\nabla\), an \(r\)-form \(\omega\) on \(M\) is called a conformal Killing form if it satisfies the differential equation: \[ \nabla\omega-\frac{1}{r+1}d\omega+g\wedge\theta=0 \] for some \((r-1)\)-form \(\theta\).
