Not only does the result itself simplify calculations, but its proof also establishes a framework for analyzing cohomology operations on the linearized Legendrian contact homology.This is the version published by Geometry & Topology on 8 December 2006Symplectic GeometryGeometric Topology57R17, 53D12, 53D40, 57M25text
