A Note on Field Redefinitions and Higher-Spin Equations
Massimo Taronna
TL;DR
This paper discusses how specific field redefinitions relate higher-spin interactions from Vasiliev's equations to those reconstructed holographically, focusing on the source terms in the Fronsdal equations.
Contribution
It provides detailed analysis of quasi-local field redefinitions connecting Vasiliev's higher-spin equations to holographic reconstructions.
Findings
Clarifies the role of field redefinitions in higher-spin interactions.
Shows the mapping between Vasiliev's equations and holographic sources.
Focuses on quadratic current interactions in the Fronsdal framework.
Abstract
In this note we provide some details on the quasi-local field redefinitions which map interactions extracted from Vasiliev's equations to those obtained via holographic reconstruction. Without loss of generality, we focus on the source to the Fronsdal equations induced by current interactions quadratic in the higher-spin linearised curvatures.
