Higher-Spin Gauge Fields and Duality
arXiv:hep-th/0501236
Abstract
We review the construction of free gauge theories for gauge fields in arbitrary representations of the Lorentz group in dimensions. We describe the multi-form calculus which gives the natural geometric framework for these theories. We also discuss duality transformations that give different field theory representations of the same physical degrees of freedom, and discuss the example of gravity in dimensions and its dual realisations in detail.
Based on the lecture presented by C.M. Hull at the First Solvay Workshop on Higher-Spin Gauge Theories, held in Brussels on May 12-14, 2004. Minor changes, added references
