Geometrical Properties of the Pseudonull Hypersurfaces in Semi-Euclidean 4-Space
In this paper, we focus on some geometrical properties of the partially null slant helices in semi-Euclidean 4-space. By structuring suitable height functions, we obtain the singularity types of the pseudonull hypersurfaces, which are generated by the ...

Kinematic Mapping in Semi-Euclidean 4-Space
We study the some algebraic properties of matrix associated to Hamilton operators is defined for semi-quaternions. The kinematic mapping corresponding to these operators in semi-Euclidean 4-space is same as the kinematic mapping of Blaschke and Grünwald ...

Osculating curves in 4-dimensional semi-Euclidean space with index 2
In this paper, we give the necessary and sufficient conditions for non-null curves with non-null normals in 4-dimensional Semi-Euclidian space with indeks 2 to be osculating curves.

Topologies of Bihyperbolic Numbers
In this paper, we establish a correlation between the bihyperbolic numbers set and the semi-Euclidean space. There are three different norms on the semi-Euclidean space that allow us to define three different hypersurfaces on semi-Euclidean space. Hence,

We consider the semi-classical expansion of the Bunch-Davies wavefunction with future boundary condition in position space for a real scalar field, conformally coupled to a classical de Sitter background in the expanding Poincaré patch with quartic ...

Singular Minimal Surfaces which are Minimal
In the present paper, we discuss the singular minimal surfaces in Euclidean $3-$space $\mathbb{R}^{3}$ which are minimal. Such a surface is nothing but a plane, a trivial outcome.

Spinorial higher-spin gauge theory from IKKT model in Euclidean and Minkowski signatures
We explore the semi-classical relation between the fuzzy 4-hyperboloid H N 4 $$ {H}_N^4 $$ and non-compact quantized twistor space ℙ N 1 , 2 $$ {\mathbb{P}}_N^{1,2} $$ at large N.
