Abstract
We study the class of plane curves with positive curvature κ and spherical parametrization s t that the curves and their derived curves like evolute caustic pedal and copedal curve resp have the same shape We characterize these properties by a homogeneous linear differential equation of first order for the support function ρ and the radii of curvature κ 1 and we give a complete local classification of this class
