Parent formulations, frame-like Lagrangians, and generalized auxiliary fields | Maxim Grigoriev
; | Date: |
9 Apr 2012 | Abstract: | We elaborate on the recently proposed Lagrangian parent formulation. In
particular, we identify a natural choice of the allowed field configurations
ensuring the equivalence of the parent and the starting point Lagrangians. We
also analyze the structure of the generalized auxiliary fields employed in the
parent formulation and establish the relationship between the parent Lagrangian
and the recently proposed Lagrange structure for the unfolded dynamics. As an
illustration of the parent formalism a systematic derivation of the frame-like
Lagrangian for totally symmetric fields starting from the Fronsdal one is
given. We also present a concise and manifestly sp(2)-symmetric form of the
off-shell constraints and gauge symmetries for AdS space symmetric fields at
the nonlinear level. | Source: | arXiv, 1204.1793 | Services: | Forum | Review | PDF | Favorites |
