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 ... -

Torus hypersurface in 4-space
(Ahi Evran Üniversitesi, 2018)We consider torus hypersurface in the four dimensional Euclideanspace E4. We give some basic notions of E4, then we define rotational hypersur-face. Finally, we define torus hypersurface, and calculate its curvatures with ... -
