Remarkably, in the special case of harmonic parameterization onto a convex subset, invertibility is guaranteed by Tutte’s graph embedding and its continuous analog, the Rado-Kneser-Choquet Theorem. I will discuss our work on generalizing these results to the non-convex case and present simple geometric conditions for invertibility.
