Quadratic pants decomposition conjecture for bilipschitz embedded surfaces

About 13 years old · traced to

Let KK be a surface of genus gg embedded in RN{\mathbb{R}}^N by a bilipschitz map, and let γ1,…,γ3g−3\gamma_1,\dots,\gamma_{3g-3} be the boundary curves of a pants decomposition of KK. Here length⁡γi\operatorname{length}\gamma_i denotes the length of γi\gamma_i, and area⁡K\operatorname{area} K denotes the area of KK. Quadratic pants decomposition conjecture. There is a pants decomposition such that

∑i(length⁡γi)2≲area⁡K.\sum_i (\operatorname{length} \gamma_i)^2\lesssim \operatorname{area} K.

The implicit constant is independent of the genus. Without the embedding hypothesis, the claim is false for generic hyperbolic surfaces, while with genus-dependent constants it follows from the systolic inequality for closed surfaces. A surface formed by adding handles to a cube is presented as a potential counterexample.
