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 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 develop massive higher-spin theory as a framework for describing dynamics of
rotating compact objects, such as Kerr black holes. In this paper, we explore gauge …

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 present higher-spin algebras containing a Poincaré subalgebra and with the
same set of generators as the Lie algebras that are relevant to Vasiliev's equations in any …

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 …

A bstract We lift the recently proposed theories of higher-spin self-dual Yang-Mills (SDYM)
and gravity (SDGR) to the twistor space. We find that the most natural room for their twistor …

There exists a unique class of local higher spin gravities with propagating massless fields in
4 d—chiral higher spin gravity. Originally, it was formulated in the light-cone gauge. We …

A bstract We consider the fuzzy 4-sphere\({S} _N^ 4\) as a background in the IKKT matrix
model, and explore the relation between\({S} _N^ 4\) and fuzzy twistor space in the semi …
