Abstract: (FIZ Karlsruhe)
A standard approach to perturbation theory of nonlinear higher-spin equations involves multiple homotopy integration that makes the whole procedure quite involved. We propose a new scheme of perturbative analysis that automatically accounts for repetitive homotopy integrals thus eliminating all intermediate steps within the standard approach. Our method gives a very efficient tool for application in perturbative higher-spin theory.- 81T20
