Massive gravity has seen a resurgence of interest due to recent progress which has
overcome its traditional problems, yielding an avenue for addressing important open …

This is a collection of my lecture notes on the higher-spin theory course given for students at
the Institute for Theoretical and Mathematical Physics, Lomonosov Moscow State University …

This white paper summarizes recent progress in the cosmological bootstrap, an approach to
the study of the statistics of primordial fluctuations from consistency with unitarity, locality and …

A bstract A key insight of the bootstrap approach to cosmological correlations is the fact that
all correlators of slow-roll inflation can be reduced to a unique building block—the four-point …

We extend the cosmological bootstrap to correlators involving massless particles with spin.
In de Sitter space, these correlators are constrained both by symmetries and by locality. In …

In this article, an introduction to the nonlinear equations for completely symmetric bosonic
higher spin gauge fields in anti de Sitter space of any dimension is provided. To make the …

Massive spin s⩾ 3/2 fields can become partially massless in cosmological backgrounds. In
the plane spanned by m2 and Λ, there are lines where new gauge invariances permit …

We study the decomposition of the Hilbert space of quantum field theory in $(d+ 1) $
dimensional de Sitter spacetime into Unitary Irreducible Representations (UIRs) of its …

We propose a self-contained description of Vasiliev higher-spin theories with the emphasis
on nonlinear equations. The main sections are supplemented with some additional material …
