Ideal Whitehead Graphs in $O u t (F_{r})$ IV: Building ideal Whitehead graphs in higher ranks and ideal Whitehead graphs with cut vertices

Catherine Pfaff

We provide an example in each rank of an ageometric fully irreducible outer automorphism whose ideal Whitehead graph has a cut vertex. Consequently, we show that there exist exampl…

A dense geodesic ray in the $O u t (F_{r})$ -quotient of reduced Outer Space

Yael Algom-Kfir, Catherine Pfaff

In 1981 Masur proved the existence of a dense geodesic in the moduli space for a Teichmüller space. We prove an analogue theorem for reduced Outer Space endowed with the Lipschitz…
