Some aspects of normal curve on smooth surface under isometry

open access: yesDemonstratio Mathematica
The normal curve is a space curve that plays an important role in the field of differential geometry. This research focuses on analyzing the properties of normal curves on smooth immersed surfaces, considering their invariance under isometric ...

Global invariants of paths and curves for the group of orthogonal transformations in the two-dimensional Euclidean space

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
In this paper, for the orthogonal group G = O(2) and special orthogonal group G = O+(2) global G-invariants of plane paths and plane curves in two-dimensional Euclidean space E2 are studied.

Radial-axial runner blade as a differentiable manifold with conformal mapping

open access: yesOpen Engineering
This article is closely tied to the author’s Radial-axial runner blade design using the coordinate slice technique. It picks up the thread of the content and follows as stated in the Future development section with conformal mapping of camber curves. The

Characterization of Speherical Helices in Euclidean 3-Space

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014
In this paper, we calculate Frenet frames of the tangent indicatrix (t), principal normal indicatrix (n) and binormal indicatrix (b) of the curve α in ℝ3 which are spherical curves.

The Pólya f-curvature of plane curves

open access: yes
We introduce and study a new curvature function for plane curves inspired by the weighted mean curvature of M. Gromov. We call it Pólya, being the difference between the usual curvature and the inner product of the normal vector field with the Pólya ...

Involutes of fronts in the Euclidean plane [PDF]

open access: yes
application/pdfFor a regular plane curve, an involute of it is the trajectory described by the end of a stretched string unwinding from a point of the curve. Even for a regular curve, the involute always has a singularity.

Geometric invariants properties of osculating curves under conformal transformation in Euclidean space ℝ3

open access: yesDemonstratio Mathematica
An osculating curve is a type of curve in space that holds significance in the study of differential geometry. In this article, we investigate certain geometric invariants of osculating curves on smooth and regularly immersed surfaces under conformal ...

Pedal and negative pedal surfaces of framed curves in the Euclidean 3-space

open access: yesOpen Mathematics
We define pedal and negative pedal surfaces of framed curves in the Euclidean 3-space and find that the loci of singularities of them are pedal and negative pedal curves, respectively. Moreover, we give sufficient conditions that pedal and negative pedal

A new frame for non-lightlike curves in Minkowski 3-space: hybrid frame

open access: yesDemonstratio Mathematica
In this study, we introduce a hybrid frame consisting of elliptic, hyperbolic, and parabolic vectors for the study of non-lightlike curves in Minkowski 3-space.

Construction of new curves on nth degree polynomial-type curves using the Flc frame

open access: yesDemonstratio Mathematica
In this study, first, the pedal curves were defined as the geometric locus of perpendicular projections onto the Frenet-like frame (Flc) vectors T, D 2, and D 1 of a given polynomial curve.
