Perturbative analysis in higher-spin theories | | V.E. Didenko

14 Dec 2015 | | Abstract: | A new scheme of the perturbative analysis of the nonlinear HS equations is
developed giving directly the final result for the successive application of
the homotopy integrations which appear in the standard approach. It drastically
simplifies the analysis and results from the application of the standard
spectral sequence approach to the higher-spin covariant derivatives, allowing
us in particular to reduce multiple homotopy integrals resulting from the
successive application of the homotopy trick to a single integral. Efficiency
of the proposed method is illustrated by various examples. In particular, it is
shown how the Central on-shell theorem of the free theory immediately results
from the nonlinear HS field equations with no intermediate computations. | | Source: | arXiv, 1512.4405 | | Services: | Forum | Review | PDF | Favorites | |
