The DGA of planar loops when 2n=4

Abstract

Abstract The DGA of planar loops is a pictorial chain complex introduced in a recent paper of the author, Boyd, Randal‐Williams and Sroka, where a minimal model for it was given. In the first non‐trivial case, , we give a new model which incorporates two natural ‘reflection’ involutions, as well as a more explicit description of the existing model.
