Cardiohelicoidal surfaces
Güler, Erhan (2019-09-06)Geometers have been working the curve theory and the surface theory for hundreds of years. We see good works for the theories in the literature. In this work, we introduce cardiohelicoidal surface in the three dimensional ... -
Cheng-yau operator and gauss map of rotational hypersurfaces in the four dimensional euclidean space
Güler, Erhan; Turgay, Nurettin Cenk (Manisa Celal Bayar University, 2018)We consider rotational hypersurface in the four dimensional Euclidean space 4E. We study the Gauss map G of rotational hypersurface in 4E with respect to the so-called Cheng-Yau operator 1L acting on the functions ... -
