• Helicoidal hypersurfaces of dini-type in the four dimensional minkowski space 

      Güler, Erhan; Kişi, Ömer (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 

      Güler, Erhan; Kişi, Ömer (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 ...
