Rotational hypersufaces in $E^4_1$ with generalized $L_k$ 1-type Gauss map [PDF]

open access: yes
In this paper, we study the Gauss map of rotational hypersurfaces in 4-dimensional Lorentz-Minkowski space concerning the linear second order differential operators $L_1$ and $L_2$, where $L_1$ is usually called as the Cheng-Yau operator.

On the quasi-minimal surfaces in the 4-dimensional . . . [PDF]

open access: yes, 2015
In this paper, we study the Gauss map of the surfaces in the de Sitter space-time S 4 1 (1). First, we prove that a space-like surface lying in the de Sitter space-time has pointwise 1-type Gauss map if and only if it has parallel mean curvature vector ...

Marginally trapped surfaces with pointwise 1-type Gauss map in Minkowski 4-space

open access: yes, 2014
A marginally trapped surface in the four-dimensional Minkowski space is a spacelike surface whose mean curvature vector is lightlike at each point. In the present paper we find all marginally trapped surfaces with pointwise 1-type Gauss map. We prove that a marginally trapped surface is of pointwise 1-type Gauss map if and only if it has parallel mean ...

Rotational embeddings in $Bbb{E}^4$ with pointwise 1-type gauss map

open access: yes, 2011
In the present article we study the rotational embedded surfaces in $Bbb{E}^4$ . The rotational embedded surface was first studied by G. Ganchev and V. Milousheva as a surface in $Bbb{E}^4$ . The Otsuki (non-round) sphere in $Bbb{E}^4$ is one of the special examples of this surface.

Some Classifications for Gauss Map of Tubular Hypersurfaces in $\mathbb{E}^{4}_{1}$ Concerning Linearized Operators $\mathcal{L}_{k}$ [PDF]

open access: yes
In this study, we deal with the Gauss map of tubular hypersurfaces in 4-dimensional Lorentz-Minkowski space concerning the linearized operators $\mathcal{L}_{1}$ (Cheng-Yau) and $\mathcal{L}_{2}$.
