Twisted Hypersurfaces in Euclidean 5-Space

Abstract

The twisted hypersurfaces x with the (0,0,0,0,1) rotating axis in five-dimensional Euclidean space E5 is considered. The fundamental forms, the Gauss map, and the shape operator of x are calculated. In E5, describing the curvatures by using the Cayley–Hamilton theorem, the curvatures of hypersurfaces x are obtained. The solutions of differential equations of the curvatures of the hypersurfaces are open problems. The umbilically and minimality conditions to the curvatures of x are determined. Additionally, the Laplace–Beltrami operator relation of x is given.

Analyzing Curvature Properties and Geometric Solitons of the Twisted Sasaki Metric on the Tangent Bundle over a Statistical Manifold

“…Gezer, Bilen, and De [25] explored almost Ricci and almost Yamabe soliton structures on the tangent bundle using the ciconia metric. Recently, Li and Khan et al studied solitons, inequalities, and submanifolds using soliton theory, submanifold theory, and other related theories [26][27][28][29][30][31]. They obtained a number of interesting results and inspired the idea of this paper.…”

Solitonical Inequality on Submanifolds in Trans-Sasakian Manifolds Coupled with a Slant Factor

“…With the aid of severe inequality, Chen [13] initiated a new framework in the study of the relationship between intrinsic and extrinsic invariants in the early 1990s, and he also presented a novel tool called δ-invariants (for more information, see [14][15][16][17]). Numerous researchers ( [18][19][20][21][22][23][24][25][26][27], etc.) carried out relevant research from various viewpoints in different spaces.…”

Bounds for Eigenvalues of q-Laplacian on Contact Submanifolds of Sasakian Space Forms

“…For the case where q > 2, we cannot apply the Holder inequality directly to control M (e 2ν ) q 2 by using M (e 2ν ). We must multiply both sides of (46) with the factor e (q−2)ν and then solve by integrating M l+1 (cf. [17]).…”
