Description
Higher-spin gauge theories become particularly simple in 2+1 dimensions, where there are no propagating degrees of freedom. Nevertheless they are useful toy models to study e.g. higher-spin generalisations of black holes or holographic dualities. Most of the research on this subject has been done in the frame-like formalism with generalised vielbeins and spin connections. I will report on recent progress on the metric-like formulation. Such a formulation might shed light on the geometric structure of higher-spin gauge theories, and it allows to apply standard field theoretic techniques like the computation of the Wald entropy for higher spin black holes.
