DESCRIPTION: Grid Peeling is the process of taking the integer grid points 
 inside a convex region and repeatedly removing the convex hull vertices. On
  the other hand\, the Affine Curve-Shortening Flow (ACSF) is defined as a p
 articular deformation of a smooth curve. It has been observed in 2017 by Ep
 pstein\, Har-Peled\, and Nivasch\, that\, as the grid is refined\, Grid Pee
 ling converges to the Affine Curve-Shortening Flow.  As part of the M.Ed. t
 hesis of Moritz Rüber\, we have investigated the grid peeling process for s
 pecial parabolas\, and we could observe some striking phenomena. This has l
 ead to the precise value of the constant that relates the two processes. Wi
 th Morteza Saghafian from IST Austria\, we could prove the convergence of g
 rid peeling for the class of parabolas with vertical axis.
