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 …

Higher Spin Gravity refers to extensions of gravity including at least one field of spin greater
than two. These extensions are expected to provide manageable models of quantum gravity …

A bstract Motivated by the prospect of constraining microscopic models, we calculate the
exact one-loop corrected de Sitter entropy (the logarithm of the sphere partition function) for …

A bstract Higher Spin Gravities are scarce, but covariant actions for them are even scarcer.
We construct covariant actions for contractions of Chiral Higher Spin Gravity that represent …

A bstract We explicitly rewrite the path integral for the free or critical O (N)(or U (N)) bosonic
vector models in d space-time dimensions as a path integral over fields (including massless …

Abstract Chiral Higher Spin Gravity with cosmological constant is constructed as a Free
Differential Algebra, ie at the level of equations of motion, which is a smooth deformation of …

A bstract A unique class of local Higher Spin Gravities with propagating massless fields in
4d—Chiral Higher Spin Gravity—was first found in the light-cone gauge. We construct a …

A bstract We propose a new approach to solve conformal field theories and apply it to Chern-
Simons Matter theories and three-dimensional bosonization duality. All three-point …

Chiral higher spin gravity is unique in being the smallest higher spin extension of gravity and
in having a simple local action both in flat and (anti-) de Sitter spaces. It must be a closed …

A covariant twistor action for chiral higher-spin theory in anti–de Sitter and flat space is
constructed in term of a holomorphic Chern-Simons theory on twistor space. The action …
