• Astrohelicoidal hypersurfaces in 4-space 

      Güler, Erhan; Kişi, Ömer (International Conference on Mathematics and Mathematics Education, 2019)
      We consider an astrohelicoidal hypersurface which its profile curve has astroid curve in the four dimensional Euclidean space E4. We also calculate Gaussian curvature and the mean curvature, and Weingarten relation of the ...
    • Astrohelicoidal surfaces 

      Güler, Erhan; Kişi, Ömer (International Conference on Mathematics and Mathematics Education, 2019)
      We construct an astrohelicoidal surface which its profile curve has astroid curve in the three dimensional Euclidean space E3. We also find Gaussian curvature and the mean curvature, and Weingarten relation of the surface ...
    • Cardiohelicoidal surfaces
