New Trends in Teichmüller Theory and Mapping Class Groups

Oberwolfach Reports, 2014
The program “New Trends in Teichmüller Theory and Mapping Class Groups” brought together people working in various aspects of the field and beyond. The focus was on the recent developments that include higher Teichmüller theory, the relation with three ...

Isophote curves on timelike surfaces in Minkowski 3-space

, 2012
Isophote comprises a locus of the surface points whose normal vectors make a constant angle with a fixed vector. In this paper, isophote curves are studied on timelike surfaces in Minkowski 3-space E31.

MANNHEIM CURVES IN AN $N$-DIMENSIONAL LORENTZ MANIFOLD

, 2014
In this paper, we give the definition of non-null Mannheim curve and null Mannheim curve in an n-dimensional Lorentz manifold. Furthermore, we give the condition for the non-null Mannheim partner curves and the null Mannhein partner curves.

Applications of a completeness lemma in minimal surface theory to various classes of surfaces

, 2010
We give several applications of a lemma on completeness used by Osserman to show the meromorphicity of Weierstrass data for complete minimal surfaces with finite total curvature.

SPACELIKE SUBMANIFOLDS IN DE SITTER SPACE

, 2010
We investigate the differential geometry of spacelike submanifolds of codimension at least two in de Sitter space as an application of the theory of Legendrian singularities.

Timelike Bertrand Curves in Semi-Euclidean Space [PDF]

, 2010
In this paper, it is proved that, no special timelike Frenet curve is a Bertrand curve in $\mathbb{E}_2^4$ and also, in $\mathbb{E}_\nu^{n+1}$ $ ({n \ge 3})$, such that the notion of Bertrand curve is definite only in $\mathbb{E}_1^2$ and $\mathbb{E}_1^3$

Computation of Smarandache curves according to Darboux frame in Minkowski 3-space

Journal of the Egyptian Mathematical Society, 2017
In this paper, we study Smarandache curves according to Darboux frame in the three-dimensional Minkowski space E13. Using the usual transformation between Frenet and Darboux frames, we investigate some special Smarandache curves for a given timelike ...

The Rosenthal-Szasz inequality for normed planes

, 2018
We aim to study the classical Rosenthal-Szasz inequality for a plane whose geometry is given by a norm. This inequality states that the bodies of constant width have the largest perimeter among all planar convex bodies of given diameter.
