Tangent and trinormal spherical images of a time-like curve on the pseudohyperbolic space H30; pp. 216–224 [PDF]
Proceedings of the Estonian Academy of Sciences, 2010 In this work tangent and trinormal spherical images of a time-like curve lying on the pseudohyperbolic space H30 in Minkowski space-time are investigated. We observe that the mentioned spherical images are space-like curves.

Some Geometrical Calculations for the Spherical Indicatrices of Involutes of a Timelike Curve in Minkowski 3-Space [PDF]
, 2013 In this paper, we introduce the spherical indicatrices of involutes of a given timelike curve. Then we give some important relationships between arc lengths and geodesic curvatures of the base curve and its involutes on E31,S21 ,H20 .

K-type slant helices on spacelike and timelike surfaces [PDF]
, 2021 We have derived a necessary and sufficient condition for a non-null normal spacelike curve lying in a spacelike or a timelike surface M ⊂ E13, so that the curve becomes a K-type spacelike slant helix with K ∈ {1,2,3}. We have used Darboux frame to define

Discriminating Quantum States in the Presence of a Deutschian CTC: A Simulation Analysis
IEEE Transactions on Quantum Engineering, 2022 In an article published in 2009, Brun et al. proved that in the presence of a “Deutschian” closed timelike curve, one can map $K$ distinct nonorthogonal states (hereafter, input set) to the standard orthonormal basis of a $K$-dimensional ...

Isometric immersions into three‐dimensional unimodular metric Lie groups
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract We study isometric immersions of surfaces into simply connected three‐dimensional unimodular Lie groups endowed with either Riemannian or Lorentzian left‐invariant metrics, assuming that Milnor's operator is diagonalizable in the Lorentzian case.

Four‐Dimensional pp‐Wave Lie Groups and Harmonic Curvature
Mathematische Nachrichten, Volume 299, Issue 7, Page 1751-1780, July 2026.ABSTRACT We determine all four‐dimensional Lie groups which have harmonic curvature. In parallel, a description of four‐dimensional pp‐wave Lie groups is obtained.

TIMELIKE V-MANNHEIM CURVES IN MINKOWSKI 3-SPACE E1^3
, 2022 In this paper, timelike V-Mannheim curve, a new type Mannheim curve in Minkowski 3-Space E_1^3 is characterized. Based on the timelike V-Mannheim curve, the properties of the timelike T, N, and B Mannheim curves are obtained.

Philosophy and Phenomenological Research, Volume 113, Issue 1, Page 134-152, July 2026.ABSTRACT Determinism is (roughly) the thesis that the past determines the future. But efforts to define it precisely have exposed deep methodological disagreements. Standard possible‐worlds formulations of determinism presuppose an “agreement” relation between worlds, but this relation can be understood in multiple ways, none of which is particularly ...

On Pseudospherical Smarandache Curves in Minkowski 3-Space
Journal of Applied Mathematics, 2014 In this paper we define nonnull and null pseudospherical Smarandache curves according to the Sabban frame of a spacelike curve lying on pseudosphere in Minkowski 3-space. We obtain the geodesic curvature and the expressions for the Sabban frame’s vectors
