Anti-Invariant Lorentzian Submersions From Lorentzian Concircular Structure Manifolds
Frontiers in Physics, 2022 This research article attempts to investigate anti-invariant Lorentzian submersions and the Lagrangian Lorentzian submersions (LLS) from the Lorentzian concircular structure [in short (LCS)n] manifolds onto semi-Riemannian manifolds with relevant non ...

Mathematics, 2020 This article has two objectives. Firstly, we use the vector variational-like inequalities problems to achieve local approximate (weakly) efficient solutions of the vector optimization problem within the novel field of the Hadamard manifolds.

Generating Geodesic Flows and Supergravity Solutions [PDF]
, 2009 We consider the geodesic motion on the symmetric moduli spaces that arise after timelike and spacellike reductions of supergravity theories. The geodesics correspond to timelike respectively spacelike p-brane Solutions when they are lifted over a p ...

Sistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2017 This research analyzes the process of the explosion of the reactor core of Chernobyl nuclear plant in April 1986, using the tensor equations. These tensor equations show a movement of a vector in the three dimensional curvature coordinates of time, water

Journal of Geometry, 2023 AbstractA nilpotent Lie algebra $$\mathfrak {n}$$ n equipped with an Euclidean inner product is called nilpotent metric Lie algebra. In this paper we describe the sets of the geodesic vectors and the flat totally geodesic subalgebras of the six-dimensional filiform metric Lie algebras. In this class with the exception

Tangent vectors to sets in the theory of geodesics [PDF]
Nagoya Mathematical Journal, 1987 In the setting of Banach manifolds the notion of tangent vector to an arbitrary closed subset has been introduced in [11] by the author and N. H. Pavel, and it has been used in flow-invariance and optimization ([11], [12], [13]). For detailed informations on tangent vectors to closed sets (including historical comments) we refer to the recent book of N.

Einstein solitons with unit geodesic potential vector field
AIMS Mathematics, 2021 The authors establish some results on almost Einstein solitons with unit geodesic potential vector field and provide necessary and sufficient conditions for the soliton to be trivial. They prove the following contributory result: Let \((g,\xi,\lambda)\) be an almost Einstein soliton on the compact and connected \(n\)-dimensional smooth manifold \(M (n ...

Quantum geodesic flows and curvature [PDF]
, 2023 We study geodesics flows on curved quantum Riemannian geometries using a recent formulation in terms of bimodule connections and completely positive maps. We complete this formalism with a canonical operation on noncommutative vector fields. We show on a

Geometrical-based algorithm for variational segmentation and smoothing of vector-valued images
, 2007 An optimisation method based on a nonlinear functional is considered for segmentation and smoothing of vector-valued images. An edge-based approach is proposed to initially segment the image using geometrical properties such as metric tensor of the ...
