On Separable Higher Gauss Maps [PDF]

open access: yesMichigan Mathematical Journal, 2019
We study the $m$-th Gauss map in the sense of F.~L.~Zak of a projective variety $X \subset \mathbb{P}^N$ over an algebraically closed field in any characteristic. For all integer $m$ with $n:=\dim(X) \leq m < N$, we show that the contact locus on $X$ of a general tangent $m$-plane is a linear variety if the $m$-th Gauss map is separable.

On the Gauss map of ruled surfaces [PDF]

open access: yesGlasgow Mathematical Journal, 1992
Let M2 be a (connected) surface in Euclidean 3-space E3, and let G:M2→S2(1) ⊂ E3 be its Gauss map. Then, according to a theorem of E. A. Ruh and J. Vilms [3], M2 is a surface of constant mean curvature if and only if, as a map from M2 to S2(1), G is harmonic, or equivalently, if and only ifwhere δ is the Laplace operator on M2 corresponding to the ...

Hypersurfaces with Generalized 1-Type Gauss Maps

open access: yesMathematics, 2018
In this paper, we study submanifolds in a Euclidean space with a generalized 1-type Gauss map. The Gauss map, G, of a submanifold in the n-dimensional Euclidean space, En, is said to be of generalized 1-type if, for the Laplace operator, Δ, on the ...

Classification Theorems of Ruled Surfaces in Minkowski Three-Space

open access: yesMathematics, 2018
By generalizing the notion of the pointwise 1-type Gauss map, the generalized 1-type Gauss map has been recently introduced. Without any assumption, we classified all possible ruled surfaces with the generalized 1-type Gauss map in a 3-dimensional ...

The hypersurfaces with conformal normal Gauss map in Hn+1 and S1n+1

open access: yesAnais da Academia Brasileira de Ciências, 2008
In this paper, we introduce the fourth fundamental forms for hypersurfaces in Hn+1 and space-like hypersurfaces in S1n+1, and discuss the conformality of the normal Gauss map of the hypersurfaces in Hn+1 and S1n+1.

Generalized Helical Hypersurface with Space-like Axis in Minkowski 5-Space

open access: yesUniverse, 2023
We introduce the generalized helical hypersurface having a space-like axis in five-dimensional Minkowski space. We compute the first and second fundamental form matrices, Gauss map, and shape operator matrix of the hypersurface.

The gauss map on a class of interval translation mappings [PDF]

open access: yesIsrael Journal of Mathematics, 2003
We study the dynamics of a class of interval translation map on three intervals. We show that in this class the typical ITM is of finite type (reduce to an interval exchange transformation) and that the complement contains a Cantor set. We relate our maps to substitution subshifts.
