چکیده
Abstract In the present paper we describe family of all closed convex plane curves class $$C^1$$ C 1 which have circles as their isoptics. first part give a certain characterization ellipses based on notion isoptic and geometric whose orthoptics are circles. The second contains considerations isoptics show form support functions considered curves.

Curves, Circles, and Spheres
The standard radius of curvature at a point q(s) on a smooth curve can be defined as the limiting radius of circles through three points that all coalesce to q(s). In the study of ideal knot shapes it has recently proven useful to consider a global radius of curvature of the curve at q(s) defined as the smallest possible radius amongst all circles passing through this point and any two other po...
متن کاملA Maximal Parallelogram Characterization of Ovals Having Circles as Orthoptic Curves
It is shown that ovals admitting circles as orthoptic curves are precisely characterized by the property that every one of their points is the vertex of exactly one maximal-perimeter inscribed parallelogram. This generalizes an old property of ellipses, most recently revived by Connes and Zagier in the paper A Property of Parallelograms Inscribed in Ellipses. Let C be a centrally symmetric smoo...
متن کاملGenerating curves and swept surfaces by blended circles
We present an improved version of the spline curve defined by H.-J. Wenz (1996) for the interpolation of 2D curve data. This trigonometrically blended spline is curvature continuous, interpolates 3D curve data, and is generated by convex combinations of circular arcs and straight line segments. As an application we show a method for rounding off the vertices of spatial polygonal lines and gener...
متن کاملElliptic Curves with Maximal Galois Action on Their Torsion Points
Given an elliptic curve E over a number field k, the Galois action on the torsion points of E induces a Galois representation, ρE : Gal(k/k) → GL2(b Z). For a fixed number field k, we describe the image of ρE for a “random” elliptic curve E over k. In particular, if k 6= Q is linearly disjoint from the cyclotomic extension of Q, then ρE will be surjective for “most” elliptic curves over k.
متن کاملOn isophote curves and their characterizations
An isophote curve comprises a locus of the surface points whose normal vectors make a constant angle with a fixed vector. The main objective of this paper is to find the axis of an isophote curve via its Darboux frame and afterwards to give some characterizations about the isophote curve and its axis in Euclidean 3-space. Particularly, for isophote curves lying on a canal surface other characte...
