Splittings of free groups from arcs and curves

Geometric Topology 2015-12-01 v1 Group Theory

Abstract

We show that the arc graph of Sg1S_g^1 is a coarse Lipschitz retract of the free splitting complex of F2gF_{2g}. We also show that the arc and curve graph of Sg1S_g^1 is a coarse Lipschitz retract of both the cyclic splitting graph of F2gF_{2g} and the maximally cyclic splitting graph of F2gF_{2g}.
