## Contribution

It introduces a new manifestly duality-invariant action principle for linearized gravity on AdS backgrounds, based on the two-potential formalism.

## Key findings

- Derived a duality-invariant action for linearized gravity in AdS.
- Connected the formulation to holographic principles.
- Provided a Hamiltonian analysis with constraints resolution.

## Abstract

We derive a manifestly duality-invariant formulation of the action principle for linearized gravity on anti de Sitter background. The analysis is based on the two-potential formalism, obtained upon resolution of the constraints in the Hamiltonian formulation. We discuss the relevance of our result in the context of holography.
