Origamis associated to minimally intersecting filling pairs
Abstract
Let denote the closed orientable surface of genus . In joint work with Huang, the first author constructed exponentially-many (in ) mapping class group orbits of pairs of simple closed curves whose complement is a single topological disk. Using different techniques, we improve on this result by constructing factorially-many (again in ) such orbits. These new orbits are chosen so that the absolute value of the algebraic intersection number is equal to the geometric intersection number, implying that each pair naturally gives rise to an origami. We collect some rudimentary experimental data on the corresponding -orbits and suggest further study and conjectures.
