Studying the Effects of Certain Curves and Metal Structures on Manifold Properties
ouriginal.sku@gmail.com ,
Abstract: The study seeks to understand the effect on geometric and topological qualities of certain curves and metal constructions on the manifold properties by investigating their effects. The research attempts to understand the effects of these components on curvature, connectivity, and general manifold behaviour by studying geodesics and closed curves inside diverse metal shapes. The work establishes important connections between curves' intrinsic qualities and metals' structural attributes by means of sophisticated mathematical methods and computer simulations. The results show that specific metal structure configurations may change the topology and curvature of the manifolds they are embedded in, which could have implications for engineering and materials research. The results shed light on the ways in which concrete objects can affect theoretically abstract geometrical spaces, adding to our knowledge of manifold theory as a whole. This discovery has far-reaching consequences; it lays the groundwork for the development of new materials with optimised geometric characteristics and paves the way for fresh uses of manifold theory in engineering. To develop and optimise structural designs, it is crucial to integrate mathematical theory with material science, as this multidisciplinary approach highlights.

INTRODUCTION
In differential geometry, CR-submanifolds have been a hotspot for study for the past four decades. In 1978, A. Bejancu introduced the notion of CR-submanifolds of a Kaehler manifold, which extends to complex and real submanifolds alike. In this paper, A. Bejancu explored many geometry issues related to CR submanifolds. Contact CR-submanifolds in Kenmotsu manifolds were subsequently the subject of study by Atceken et al., who uncovered some intriguing features.
Professor D. E. Blair first proposed the idea of a Killing tensor field in 1971. Many writers have studied the class of almost contact manifolds first studied by K. Kenmotsu in 1972, which is called a Kenmotsu manifold (Ratiu, T. 2008).
One specific kind of almost contact metric manifold is called a Kenmotsu manifold, and it is defined by the fact that (∇𝑋𝜙)=−𝑔(𝜙𝑋,𝑌)𝜉+𝜂(𝑌)𝜙𝑋, This stands for the Levi-Civita relationship of 𝑏. Because of its unique geometric features, the Kenmotsu manifold is a great place to explore Contact CR-submanifolds and other submanifold structures. The existence of a CR (Cauchy-Riemann) structure, a naturally occurring extension of the complex structure in the theory of multiple complex variables to the context of nearly contact metric manifolds, defines these submanifolds. In particular, the splitting of the tangent bundle 𝑇𝑁 into two orthogonal subbundles defines a Contact CR-submanifold 𝑁 of an almost contact metric manifold 𝑀 𝐷=𝑇𝑁∩ker(𝜂) alongside the range of 
The subbundle 𝐷 remains unchanged when 𝜙 is applied. Meaning (𝐷)⊆𝐷 (Biswas, 2014). Additionally, 𝐷 divides into 𝐷=𝐷1⊕𝐷2, where 𝐷1 represents a complicated subbundle of 𝐷 (i.e., (𝐷1)=𝐷1and 𝐷2 it is orthogonal to in 𝐷 (i.e., 𝜙(𝐷2)⊆𝐷1. The duality and interplay of the holomorphic and fully real components of the submanifold's geometry are mirrored by this splitting. (Ojha, R. H. 2011)
