The Gauss map of surfaces in PSL˜2(R) [PDF]

open access: yes, 2015
We define a Gauss map for surfaces in the universal cover of the Lie group PSL2(R) endowed with a left-invariant Riemannian metric having a 4-dimensional isometry group. This Gauss map is not related to the Lie group structure. We prove that the Gauss

Cheng-Yau operator and Gauss map of surfaces of revolution [PDF]

open access: green, 2014
We study the Gauss map G of surfaces of revolution in the 3-dimensional Euclidean space $${{\mathbb {E}}^3}$$E3 with respect to the so-called Cheng–Yau operator $$\square $$□ acting on the functions defined on the surfaces.

Differential Geometry of 1-type Submanifolds and Submanifolds with 1-type Gauss Map

open access: yesInternational Electronic Journal of Geometry, 2023
The theory of finite type submanifolds was introduced by the first author in late 1970s and it has become a useful tool for investigation of submanifolds. Later, the first author and P.

Harmonic Gauss maps [PDF]

open access: yesPacific Journal of Mathematics, 1989
A construction is given whereby a Riemannian manifold induces a Riemannian metric on the total space of a large class of fibre bundles over it. Using this metric on the appropriate bundles, necessary and sufficient conditions are given for the Gauss map and the spherical Gauss map to be harmonic.

On special developable ruled surfaces with pointwise 1-type Gauss map

open access: yesMiskolc Mathematical Notes, 2021
. In this paper, some special developable ruled surfaces with point-wise Gauss map are studied. Three different special developable ruled surfaces called rectifying ruled surface, generalized normal ruled surface and osculating type ruled surface are ...

Hypersurfaces with pointwise 1-type Gauss map in Lorentz–Minkowski space; 146–161 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2009
Hypersurfaces of a Lorentz–Minkowski space Ln+1 with pointwise 1-type Gauss map are characterized. We prove that an oriented hypersurface Mq in Ln+1 has pointwise 1-type Gauss map of the first kind if and only if Mq has constant mean curvature and ...

Geometric characterizations of canal surfaces with Frenet center curves

open access: yesAIMS Mathematics, 2021
In this work, we study the canal surfaces foliated by pseudo hyperbolic spheres $ \mathbb{H}_{0}^{2} $ along a Frenet curve in terms of their Gauss maps in Minkowski 3-space.

SUBMANIFOLDS WITH BIHARMONIC GAUSS MAP [PDF]

open access: yesInternational Journal of Mathematics, 2010
We generalize the Ruh–Vilms problem by characterizing the submanifolds in Euclidean spaces with proper biharmonic Gauss map and we construct examples of such hypersurfaces.

Quad Key-Secured 3D Gauss Encryption Compression System with Lyapunov Exponent Validation for Digital Images

open access: yesApplied Sciences, 2023
High-dimensional systems are more secure than their lower-order counterparts. However, high security with these complex sets of equations and parameters reduces the transmission system’s processing speed, necessitating the development of an algorithm ...
