Non-Hermitian Dirac Hamiltonian in Three-Dimensional Gravity and Pseudosupersymmetry
Advances in High Energy Physics, 2015 The Dirac Hamiltonian in the (2+1)-dimensional curved space-time has been studied with a metric for an expanding de Sitter space-time which is two spheres.

A mandala of Legendrian dualities for pseudo-spheres in semi-Euclidean space
, 2008 We show six Legendrian dualities between pseudo-spheres in semi-Euclidean space which are basic tools for the study of extrinsic differential geometry of submanifolds in these pseudo-spheres.

RULED SURFACES AND TANGENT BUNDLE OF PSEUDO-SPHERE OF NATURAL LIFT CURVES
Journal of Science and Arts, 2020 In this article, firstly, the isomorphism between the subset of the tangent bundle of Lorentzian unit sphere, TM, and Lorentzian unit sphere, S12 is represented. Secondly, the isomorphism between the subset of hyperbolic unit sphere, TM, and hyperbolic unit sphere, H2 is given. According to E.

INTERSECTIONS OF RULED SURFACES CORRESPONDING TO CURVES ON PSEUDO SPHERES IN DUAL SPACE
Journal of Science and Arts, 2023 In this article, firstly, the intersection of two ruled surfaces corresponding to two different curves on S_1^2 is investigated. The conditions for the intersection of these ruled surfaces in R_1^3 are expressed by theorems with bivariate functions. Then, the intersection of two ruled surfaces corresponding to two different curves on H^2 is examined ...

Extensions of the mandala of Legendrian dualities for pseudo-spheres in Lorentz-Minkowski space
, 2009 In this paper we show one-parameter families of Legendrian dualities between pseudo-spheres in Lorentz-Minkowski space which are the extensions of four dualities in the previous research.
