Self-intersections of arcs on a pair of pants

Geometric Topology 2024-07-26 v1 Combinatorics

Abstract

We investigate arcs on a pair of pants and present an algorithm to compute the self-intersection number of an arc. Additionally, we establish bounds for the self-intersection number in terms of the word length. We also prove that the spectrum of self-intersection numbers of 2-low-lying arcs covers all natural numbers.
