Evolutes and Involutes of Frontals in the Euclidean Plane
Evolutes and Involutes of Frontals in the Euclidean Plane
Abstract We have already defined the evolutes and the involutes of fronts without inflection points. For regular curves or fronts, we can not define the evolutes at inflection points. On the other hand, the involutes can be defined at inflection points. In this case, the involute is not a front …
