TY - JOUR T1 - Rotational Hypersurfaces Satisfying ∆^I R=AR in the Four-Dimensional Euclidean Space TT - Rotational Hypersurfaces Satisfying ∆^I R=AR in the Four-Dimensional Euclidean Space AU - Güler, Erhan PY - 2021 DA - June DO - 10.2339/politeknik.670333 JF - Politeknik Dergisi PB - Gazi Üniversitesi WT - DergiPark SN - 2147-9429 SP - 517 EP - 520 VL - 24 IS - 2 LA - en AB - In this study, rotational hypersurfaces in the 4-dimensional Euclidean space are discussed. Some relations of curvatures of hypersurfaces are given, such as the mean, Gaussian, and their minimality and flatness. In addition, Laplace-Beltrami operator has been defined for 4-dimensional hypersurfaces depending on the first fundamental form. Moreover, it is shown that each element of the 4×4 order matrix A, which satisfies the condition ∆^I R=AR, is zero, that is, the rotational hypersurface R is minimal.
