| Oct 2, 2014 at 19:43 | comment | added | Joonas Ilmavirta | If you construct the peeling function by expanding $P(0)$ step by step, $P(t)$ is always connected. It seems intuitively possible to first expand $P(t)$ so that $P(1)\setminus P(\frac12)$ is simply connected (cutting the loops in $P(1)\setminus P(0)$) and then shrink the simply connected set away. I'm not sure I can formalize this two-step procedure properly, though. | |
| Oct 2, 2014 at 18:50 | comment | added | Erel Segal-Halevi | @JoonasIlmavirta This sounds promising, but how do you guarantee the connectivity? | |
| Oct 2, 2014 at 18:26 | comment | added | Joonas Ilmavirta | A naive suggestion: Triangulate $P(1)\setminus P(0)$ (the complement of the union of the pulp and the head) and proceed triangle by triangle. Have you tried anything along these lines? | |
