Fractional-order differential geometry of Gielis curves: chart regularization, Caputo curvature, and the fate of singularities

Umut Selvi, Derya Sağlam

Gielis curves describe many natural shapes, and some of them have corners or cusps. We apply two recent ideas from the differential geometry of curves to Gielis curves: "regularizi…
