The medial axis of a closed set collects all the points of the ambient space with nonunique distance realiser in a set. This paper studies which of the set's singular points are reached by the medial axis. The investigation of C 1 \\mathscr {C}^1 smoothness points extends earlier ...

<p>To determine which points lie on the x-axis, we need to understand the condition for a point to be on the x-axis in the coordinate plane. A point is represented as (x, y), where 'x' is the x-coordinate and 'y' is the y-coordinate. For a point to lie o
