Computing Euler characteristics using quantum field theory

Michael Borinsky, Karen Vogtmann

This paper explains how to use quantum field theory techniques to find formal power series that encode the virtual Euler characteristics of $Out (F_{n})$ and related graph co…

The Euler characteristic of $Out (F_{n})$

Michael Borinsky, Karen Vogtmann

We prove that the rational Euler characteristic of $Out (F_{n})$ is always negative and its asymptotic growth rate is $Γ (n - \frac{3}{2}) / 2 π lo g^{2} n$ . This settles a…
