要旨:
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, including introduction to gravity as a gauge theory;
the review of the Fronsdal formulation of free higher-spin fields; Young
diagrams and tensors as well as sections with advanced topics. The general
discussion is dimension independent, while the essence of the Vasiliev
formulation is discussed on the base of the four-dimensional higher-spin
theory. Three-dimensional and $d$-dimensional higher-spin theories follow the
same logic.
