A-type Sigma Models from Differential Poisson Geometry
Cesar Arias, Per Sundell
We study the differential Poisson sigma model (DPSM) in the symplectic case and show that its classical reduction defines a distinguished class of A-type models on symplectic targe…
Fractional Spins, Unfolding, and Holography: II. 4D Higher Spin Gravity and 3D Conformal Dual
Felipe Diaz, Carlo Iazeolla, Per Sundell
This paper completes the analysis initiated in the companion work arXiv:2403.02283 -- referred to as Paper I -- by showing how Vasiliev's 4D higher-spin gravity (HSG) and 3D colour…
Fractional Spins, Unfolding, and Holography: I. Parent field equations for dual higher-spin gravity reductions
Felipe Diaz, Carlo Iazeolla, Per Sundell
In this work and in the companion paper arXiv:2403.02301, we initiate an approach to holography based on the AKSZ formalism. As the first step, we refine Vasiliev's holography prop…
Logarithmic Corrections, Entanglement Entropy, and UV Cutoffs in de Sitter Spacetime
Gabriel Arenas-Henriquez, Felipe Diaz, Per Sundell
It has been argued that the entropy of de Sitter space corresponds to the entanglement between disconnected regions computable by switching on a replica parameter modeled by th…
Unfolding, higher spins, metaplectic groups and resolution of classical singularities
Carlo Iazeolla, Per Sundell
We review and extend some recent results concerning the analysis of spacetime singularities in four-dimensional higher spin gravity, summarizing how the coupling of the gravitation…
Metaplectic representation and ordering (in)dependence in Vasiliev's higher spin gravity
David De Filippi, Carlo Iazeolla, Per Sundell
We investigate the formulation of Vasiliev's four-dimensional higher-spin gravity in operator form, without making reference to one specific ordering. More precisely, we make use o…
