Abstract
The study of the singularities of plane curves (real in our case) is a classic subject. The plane can be endowed with a metric, for example the Euclidean or Minkowski metric. Thus, when deforming the curve, it expected that the geometry concentrated at the singularity (vertices, inflections, bi-tangencies, self-intersections, light-like points in the case of curves in the Minkowski plane)…
