Laplace-Beltrami Operator of a Helicoidal Hypersurface in Four-Space

, 2016
Communicated by Ivaïlo Mladenov Abstract. We introduce helicoidal hypersurface in the four dimensional Euclidean space. We calculate the mean and the Gaussian curvature, and some relations of the helicoidal hypersurface. Then we give the Laplace-Beltrami

On the Involute and Evolute Curves of the Spacelike Curve with a Spacelike Binormal in Minkowski 3−Space

, 2007
In this study, we have generalized the involute and evolute curves of the spacelike curve α with a spacelike binormal in Minkowski 3- Space. Firstly, we have shown that, the length between the spacelike curve α and the timelike curve β is constant ...

On rotational surfaces in conformally flat 3-space

, 2016
In this paper, we deal with linear Weingarten rotational surfaces in a conformally flat 3-space F3 satisfying κ̃1 = mκ̃2, where κ̃1 and κ̃2 are the principal curvatures of a rotational surface in F3 and m is a non-zero constant.

Singular Points of Tubular Surfaces in Minkowski 3-Space

Sarajevo Journal of Mathematics
In this paper, we examine singular points of tubular surfaces and its parallel surfaces, which is based on two-parameter spatial motion along a curve in Minkowski 3-space. Related results are presented also.
