DESCRIPTION: Grid Peeling is the process of taking the integer grid points
inside a convex region and repeatedly removing the convex hull vertices. By
contrast\, the Affine Curve-Shortening Flow (ACSF) is defined as a particu
lar deformation of a smooth curve. It has been observed in 2017 by Eppstein
\, Har-Peled\, and Nivasch\, that\, as the grid is refined\, Grid Peeling c
onverges to the Affine Curve-Shortening Flow. As part of the M.Ed. thesis
of Moritz Rüber\, we have investigated the grid peeling process for special
parabolas\, and we could observe some striking phenomena. This has lead to
the precise value of the constant that relates the two processes. With Mor
teza Saghafian from IST Austria\, we could prove the convergence of grid pe
eling for the class of parabolas with vertical axis.
