On the Gauss map of $B$-scrolls

open access: yesTsukuba Journal of Mathematics, 1998
Let \(M\) be a ruled surface in the 3-dimensional Lorentz-Minkowski space \({\mathbb L}^3\) defined by \(X(s,t)=x(s)+tB(s)\), where \((x , F)\) is a null curve with frame \(F=\{A,B,C\}\). \(M\) is called a B-scroll if \(F\) is a Cartan frame, i.e., \(A, B, C\) are vector fields along \(x\) in \({\mathbb L}^3\) satisfying the conditions \(\langle A, A ...

A noncommutative Gauss map

open access: yesMATHEMATICA SCANDINAVICA, 2011
The aim of this paper is to transfer the Gauss map, which is a Bernoulli shift for continued fractions, to the noncommutative setting. We feel that a natural place for such a map to act is on the AF algebra $\mathfrak A$ considered separately by F. Boca and D. Mundici.

The Generalized Gauss Map and Applications

open access: yesRocky Mountain Journal of Mathematics, 1993
The authors define a Gauss map for hypersurfaces in a Riemannian parallelizable manifold and study its properties. Applying these results they generalize some classical results of Differential Geometry.

New official cartographic projection of Serbia [PDF]

open access: yesVojnotehnički Glasnik, 2012
A review of the elements of the mathematical base of our topographic maps is given. The Gauss-Kruger's conformal cylindric projection has been applied so far in Serbia and in the future the transversal Mercator's projection will be the official mapping ...

A Gauss-Kuzmin-Lévy theorem for a certain continued fraction

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We consider an interval map which is a generalization of the well-known Gauss transformation. In particular, we prove a result concerning the asymptotic behavior of the distribution functions of this map.

SLAM on the Hexagonal Grid

open access: yesSensors, 2022
Hexagonal grids have many advantages over square grids and could be successfully used in mobile robotics as a map representation. However, there is a lack of an essential algorithm, namely, SLAM (simultaneous localization and mapping), that would ...
