Intrinsic Finite-Step Characterizations of Discrete General Helices
Dae Won Yoon, Chul Woo Lee, Jae won Lee
We study polygonal general helices in Euclidean three-space using the turning and signed torsion angles of the discrete Frenet frame. For helices whose axis is not orthogonal to th…

Canal Hypersurfaces Generated by Non-Null Curves with Parallel Frame in Minkowski Space-Time
Mustafa Altın, Ahmet Kazan, Dae Won Yoon
In the present paper, firstly we obtain the canal hypersurfaces that are formed as the envelope of a family of pseudo hyperspheres or pseudo hyperbolic hyperspheres whose centers l…

Timelike General Rotational Surfaces in Minkowski 4-Space with Density
Ahmet Kazan, Mustafa Altın, Dae Won Yoon
In this study, we give weighted mean and weighted Gaussian curvatures of two types of timelike general rotational surfaces with non-null plane meridian curves in four-dimensional M…
