Labeled Double Pants Decompositions
A double pants decomposition of a 2-dimensional surface is a collection of two pants decomposition of this surface introduced by the authors. There are two natural operations acting on double pants decompositions: flips and handle-twists. It is shown by the authors that the groupoid generated by flips and handle-twists acts transitively on admissible double pants decompositions, where the class...
متن کاملPants Decompositions of Surfaces
In studying the geometry and topology of surfaces it often happens that one considers a collection of disjointly embedded circles in a compact orientable surface Σ which decompose Σ into pairs of pants — surfaces of genus zero with three boundary circles. If Σ is not itself a pair of pants, then there are infinitely many different isotopy classes of pants decompositions of Σ. It was observed in...
متن کاملAutomorphisms of the Pants Complex
In loving memory of my mother, Batya 1. Introduction In the theory of mapping class groups, " curve complexes " assume a role similar to the one that buildings play in the theory of linear groups. Ivanov, Korkmaz, and Luo showed that the automorphism group of the curve complex for a surface is generally isomorphic to the extended mapping class group of the surface. In this paper, we show that t...
متن کاملSimplicial Embeddings between Pants Graphs
We prove that, except in some low-complexity cases, every locally injective simplicial map between pants graphs is induced by a π1-injective embedding between the corresponding surfaces.
متن کاملOptimizing Geometry-aware Pants Decomposition
We present a computational framework to optimize the pants decomposition of surfaces with non-trivial topology. A pants decomposition segments a surface into a set of sub-patches each of which is genus-0 with 3 boundaries. A given surface usually admits infinitely-many pants decompositions that are topologically inequivalent. Given some pre-determined geometric criteria, our algorithm enumerate...
