Half-Lightlike Submanifolds of Metallic semi-Riemannian Manifolds
, 1997 The aim of the present paper is to study half-lightlike submanifolds of a semi-Riemannian manifold endowed with a metallic structure. We introduce a special half-lightlike submanifold called screen semi-invariant half lightlike submanifold in metallic ...

Concepts and examples in Riemannian geometry
, 2021 In this paper, we explore various notations and definitions, in Riemannian Geometry, which were created during the past century. Next, we developed a few clear examples from the book RIEMANNIAN GEOMETRY written by Do Carmo and explain the article A THE ...

Spectral Geometry for Structural Pattern Recognition [PDF]
, 2010 Graphs are used pervasively in computer science as representations of data with a network or relational structure, where the graph structure provides a flexible representation such that there is no fixed dimensionality for objects. However, the analysis

Riemannian Maps To Almost Hermitian Manifolds
, 2017 In this chapter, we study Riemannian maps from Riemannian manifolds to almost Hermitian manifolds. In section 1, we study invariant Riemannian maps, that is, the image of derivative map is invariant under the almost complex structure of the base manifold.

Degenerate Foliations in Sasakian Semi-Riemannian Manifolds [PDF]
In the Semi-Riemannian case we do not have the liability of the existence of such a metric being a difference from the Riemannian case. A Semi-Riemannian manifold provided with a normal contact metric structure is called Sasakian manifold.Semi-Riemannian,

Riemannian Maps From Almost Hermitian Manifolds
, 2017 In this chapter, we study Riemannian maps from almost Hermitian manifolds to Riemannian manifolds. In section 1, we study holomorphic Riemannian maps as a generalization of holomorphic submersions and obtain a characterization of such maps. In section 2,

A Pinching Theorem for Compact Minimal Submanifolds in Warped Products
, 2020 Let Sm(c) be a Euclidean sphere of curvature c>0 and R be a Euclidean line. We prove a pinching theorem for compact minimal submanifolds immersed in Riemannian warped products of the type I×fSm(c), where f:I→R+ is a smooth positive function on an open

Global Eikonal Condition for Lorentzian Distance Function in Noncommutative Geometry [PDF]
, 2010 Connes' noncommutative Riemannian distance formula is constructed in two steps, the first one being the construction of a path-independent geometrical functional using a global constraint on continuous functions. This paper generalizes this first step to
