On convolutions of algebraic curves

We focus on the investigation of relations between plane algebraic curves and their convolution. Since the convolution of irreducible algebraic curves is not necessarily irreducible, an upper bound for the number o...

Algebraic Curves Given by Puiseux Tree

Puiseux tree represents locally planar curve branches at a given point. It is well known how to find Puiseux tree from the algebraic equation of the curve. We consider the other direction and propose an algorithm to find

Symmetries and similarities of planar algebraic curves using harmonic polynomials

We present novel, deterministic, efficient algorithms to compute the symmetries of a planar algebraic curve, implicitly defined, and to check whether or not two given implicit planar algebraic curves are similar, i...

Exploration of dual curves using dynamic geometry and computer algebra system

This submission deals with the use of the dynamic mathematics software GeoGebra to determine the dual curve to the given curve and inspect its properties. The combination of dynamic geometry tools with computer algebra func...

Algebraic Curves of Low Convolution Degree

of planar algebraic curves with respect to the operation of convolution, namely on the curves with theconvolution degree one (so called LN curves) and two. We will present an algebraic analysis of these <...

Approximate parameterizations of space algebraic curves

an approximate parameterization of space algebraic curves. Firstly, we determine a space graph which is topologically equivalent to an implicit algebraic space curve. Then, a computation of a spline curve...

Approximate symmetries of planar algebraic curves with inexact input

In this paper, we formulate a simple algorithm for an approximate reconstruction of an inexact planar curve which is assumed to be a perturbation of some unknown planar curve with symmetry. The input curve is given by a per...

Local Properties of Algebraic Curves Using Rational Puiseux Series

properties of algebraic curves at their singular points. In particular we exploit the existence of a bijection between the curve real branches and set of rational Puiseux series at a given point of the curve. We d...

Exploiting the Implicit Support Function for a Topologically Accurate Approximation of Algebraic Curves

Describing the topology of real algebraic curves is a classical problem in computational algebraic geometry. It is usually based on algebraic techniques applied directly to the curve equation. We use the i...

Drawing and investigation of curves in GeoGebra

Possible ways of an effective use of the combination of tools of dynamic geometry and computer algebra features of GeoGebra are presented by means of particular examples in the contribution. The curves are considered as locus cu...
