Aiming at nonexperts, the key mechanisms of higher-spin extensions of ordinary gravities in
four dimensions and higher are explained. An overview of various no-go theorems for low …

The antibracket formalism for gauge theories, at both the classical and quantum level, is
reviewed. Gauge transformations and the associated gauge structure are analyzed in detail …

The quantization rules for gauge theories with open algebras are generalized to the case of
linearly dependent generators. The given zero-eigenvalue eigenvectors of the generators …

Physics below 300 GeV is termed infrared, and physics above 1 TeV is called ultraviolet.
Some aspects of the relation between these two regions are discussed. It is argued that the …

Consistent equations of motion of interacting gauge fields of all spins in 3+ 1 dimensions are
formulated in a closed form. These equations are explicitly general coordinate invariant …

We show that in all theories with a Lorentz-covariant energy-momentum tensor, such as all
known renormalizable quantum field theories, composite as well as elementary massless …

An attempt is made to construct a realistic model of particle physics based on eleven-
dimensional supergravity with seven dimensions compactified. It is possible to obtain an SU …

We show that, despite a widespread belief, the gravitational interaction of massless higher-
spin fields (s> 2) does exist at least in the first nontrivial order. The principal novel feature of …

We review the theory of higher spin gauge fields in 2+ 1 and 3+ 1 dimensional anti-de Sitter
space and present some new results on the structure of higher spin currents and explicit …

A cubic interaction of all massless higher-spin fields with s⩾ 1 is constructed, based on the
extended higher-spin superalgebras suggested previously by one of us (MV). This …
