This article. in the introduction, gives a brief historic description on surfaces of finite Chen-
type and of coordinate finite Chen-type according to the first, second and third fundamental …

In this paper, we study the conchodial surfaces in 3-dimensional Euclidean space with the
condition Δx_i=λ_ix_i where Δ denotes the Laplace operator with respect to the first …

In this article, we focus on quadric surfaces from two sides. On one side, we study quadric
surfaces of the first kind whose position vector r satisfies a relation of the form Δ II r= Ar …

Numerous applications, like robot navigation, network verification and discovery,
geographical routing protocols, and combinatorial optimization, make use of the metric …

This paper calculates the exact quantiles of the MLE of Shannon entropy of the Nakagami
distributions and approximate quantiles of the asymptotic distribution of this statistic. In …

Translational surfaces in 3-dimensional Euclidean space (E3) areused in various fields,
