Elements of Vasiliev theory

Understand

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 shortest route to Vasiliev equations covers 40 pages.
• 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.
