The Geometry of the Centre Symmetry Set of a Planar Curve
arXiv:2204.11132
Abstract
The Centre Symmetry Set of a planar curve is the envelope of affine chords of , i.e. the lines joining points on with parallel tangent lines. In this paper we study global geometrical properties of this set including the number of singularities and the number of asymptotes.
