An introduction to Smarandache multi-spaces and mathematical combinatorics [PDF]

open access: yes, 2007
These Smarandache spaces are right theories for objectives by logic. However, the mathematical combinatorics is a combinatorial theory for branches in classical mathematics motivated by a combinatorial speculation.

The Proximal Gradient Method for Composite Optimization Problems on Riemannian Manifolds

open access: yesMathematics
In this paper, the composite optimization problem is studied on Riemannian manifolds. To tackle this problem, the proximal gradient method to solve composite optimization problems is proposed on Riemannian manifolds. Under some reasonable conditions, the

Anti-Invariant Semi-Riemannian Submersions from Almost Para-Hermitian Manifolds

open access: yesJournal of Function Spaces and Applications, 2013
We introduce anti-invariant semi-Riemannian submersions from almost para-Hermitian manifolds onto semi-Riemannian manifolds. We give an example, investigate the geometry of foliations which are arisen from the definition of a semi-Riemannian submersion ...

On the Geometry of Three-dimensional Pseudo-Riemannian Homogeneous Spaces. II [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020
The problem of establishing links between the curvature and the topological structure of a manifold is one of the important problems of the geometry. In general, the purpose of the research of manifolds of various types is rather complicated.

On Geometric Phase Model in the Theory of Curves With Myller Configuration

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we introduce a linearly polarized light wave in an optical fiber and rotation of the polarization plane through the Frenet‐type frame with Myller configuration. Since the geometric evaluation and interpretations of a polarized light wave are associated with geometric phase, a new type of geometric phase model has been ...

Anti-invariant Riemannian submersions from cosymplectic manifolds onto Riemannian manifolds [PDF]

open access: yes, 2015
We introduce anti-invariant Riemannian submersions from cosymplectic manifolds onto Riemannian manifolds. We survey main results of anti-invariant Riemannian submersions defined on cosymplectic manifolds. We investigate necessary and sufficient condition

A Comprehensive Review of Golden Riemannian Manifolds

open access: yesAxioms
In differential geometry, the concept of golden structure represents a compelling area with wide-ranging applications. The exploration of golden Riemannian manifolds was initiated by C. E. Hretcanu and M.

On Ricci Riemannian Manifolds

open access: yesAnnals of the Alexandru Ioan Cuza University - Mathematics, 2010
Summary: The object of this paper is to study some properties of a type of Riemannian manifold called Ricci Riemannian manifold \((M^n,g),n>2\). The perfect fluid space time \((M^4,g)\) of general relativity is also studied.

Initial State Privacy of Nonlinear Systems on Riemannian Manifolds

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this paper, we investigate initial state privacy protection for discrete‐time nonlinear closed systems. By capturing Riemannian geometric structures inherent in such privacy challenges, we refine the concept of differential privacy through the introduction of an initial state adjacency set based on Riemannian distances.
