Pseudo-Anosov homeomorphisms of punctured non-orientable surfaces with small stretch factor

Geometric Topology 2023-09-13 v2

Abstract

We prove that in the non-orientable setting, the minimal stretch factor of a pseudo-Anosov homeomorphism of a surface of genus gg with a fixed number of punctures is asymptotically on the order of 1g\frac{1}{g}. Our result adapts the work of Yazdi to non-orientable surfaces. We include the details of Thurston's theory of fibered faces for non-orientable 3-manifolds.
