Asymptotes of Plane Curves - Revisited (original) (raw)

Asymptotes of space curves

Journal of Computational and Applied Mathematics, 2015

In this paper, we generalize the results presented in [4] for the case of real algebraic space curves. More precisely, given an algebraic space curve C implicitly defined, we show how to compute the generalized asymptotes. In addition, we show how to deal with this problem for the case of a given curve C parametrically defined. The approaches are based on the notion of approaching curves introduced in [5].

Asymptotes and perfect curves

Computer Aided Geometric Design, 2014

We develop a method for computing all the generalized asymptotes of a real plane algebraic curve C over C implicitly defined by an irreducible polynomial f (x, y) ∈ R[x, y]. The approach is based on the notion of perfect curve introduced from the concepts and results presented in [2].

A new approach for computing the asymptotes of a parametric curve

Journal of Computational and Applied Mathematics, 2020

In this paper, we summarize two algorithms for computing all the generalized asymptotes of a plane algebraic curve implicitly or parametrically defined. The approach is based on the notion of perfect curves introduced from the concepts and results presented in previous papers of the same authors. From these results, we derive a new and efficient method that allows to easily compute all the generalized asymptotes of an algebraic curve parametrically defined in n-dimensional space.

Asymptotic behavior of an implicit algebraic plane curve

Computer Aided Geometric Design, 2014

In this paper, we introduce the notion of infinity branches as well as approaching curves. We present some properties which allow us to obtain an algorithm that compares the behavior of two implicitly defined algebraic plane curves at the infinity. As an important result, we prove that if two plane algebraic curves have the same asymptotic behavior, the Hausdorff distance between them is finite.

Some New Symbolic Algorithms for the Computation of Generalized Asymptotes

Symmetry

We present symbolic algorithms for computing the g-asymptotes, or generalized asymptotes, of a plane algebraic curve, C, implicitly or parametrically defined. The g-asymptotes generalize the classical concept of asymptotes of a plane algebraic curve. Both notions have been previously studied for analyzing the geometry and topology of a curve at infinity points, as well as to detect the symmetries that can occur in coordinates far from the origin. Thus, based on this research, and in order to solve practical problems in the fields of science and engineering, we present the pseudocodes and implementations of algorithms based on the Puiseux series expansion to construct the g-asymptotes of a plane algebraic curve, implicitly or parametrically defined. Additionally, we propose some new symbolic methods and their corresponding implementations which improve the efficiency of the preceding. These new methods are based on the computation of limits and derivatives; they show higher computati...

Offset surface pencil with a common asymptotic curve

International Journal of Geometric Methods in Modern Physics, 2018

Let [Formula: see text] be a parameter and an asymptotic curve on a surface [Formula: see text] We obtain conditions for offsets [Formula: see text] of [Formula: see text] such that the image [Formula: see text] of the curve [Formula: see text] is a common asymptotic on each offset. We illustrate the method with an example.

Asymptotic Behavior of a Surface Implicitly Defined

Mathematics

In this paper, we introduce the notion of infinity branches and approaching surfaces. We obtain an algorithm that compares the behavior at the infinity of two given algebraic surfaces that are defined by an irreducible polynomial. Furthermore, we show that if two surfaces have the same asymptotic behavior, the Hausdorff distance between them is finite. All these concepts are new and represent a great advance for the study of surfaces and their applications.

Asymptotic Curves on Surfaces in ℝ 5

Communications in Contemporary Mathematics, 2008

We study asymptotic curves on generically immersed surfaces in ℝ5. We characterize asymptotic directions via the contact of the surface with flat objects (k-planes, k = 1 - 4), give the equation of the asymptotic curves in terms of the coefficients of the second fundamental form and study their generic local configurations.

A General Formula for Asymptotes of Rational Polynomial Functions

2021

We propose a formula for finding the horizontal, oblique or curvilinear asymptote of any rational polynomial function of any positive degree, as a sum of matrix determinants formed directly from the coefficients of the terms in the given polynomial. This formula provides a new means of computing asymptotes in addition to the standard methods of Euclidean division and the evaluation of limits.
