• Dini-type helicoidal hypersurfaces with timelike axis in minkowski 4-space E14 

      Güler, Erhan; Kişi, Ömer (Mathematics, 2019)
      We consider Ulisse Dini-type helicoidal hypersurfaces with timelike axis in Minkowski 4-space E41 . Calculating the Gaussian and the mean curvatures of the hypersurfaces, we demonstrate some special symmetries for the ...
    • Helicoidal hypersurfaces in the four dimensional minkowski space 

      Güler, Erhan; Kaimakamis, George; Magid, Martin (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 ...
