Helicoidal hypersurfaces in the four dimensional minkowski space
(Manisa Celal Bayar University, 2018)Helicoidal hypersurfaces in the four dimensional Minkowski space are defined. There are three types, depending on the axis of rotation. Equations for the Gaussian and mean curvature are derived and many ... -
Helicoidal hypersurfaces of dini-type in the four dimensional minkowski space
(Karaman Üniversitesi, 2018)We define Ulisse Dini-type helicoidal hypersurfaces with spacelikeaxis in Minkowski 4-spaceE41. We compute the Gaussian and the mean curva-ture of the hypersurface. Moreover, we obtain some special symmetries to thecurvatures ... -
Helicoidal surface of logaritmic spiral type in 3-space
(International Conference on Computational Mathematics and Engineering Sciences, 2019)In this paper, we study the logaritmic spiral-type helicoidal surface in Euclidean 3-space. We obtain logaritmic spiral-type helicoidal surface with some figures, and calculate its curvatures. -
