Query: Duality in Gravity and Higher Spin Gauge Fields   Dual field theory realisations are given for linearised gravity in terms of
gauge fields in exotic representations of the Lorentz group. The field
equations and dual representations are discussed for a wide class of higher
spin gauge fields. For non-linear Einstein gravity, such transformations can be
implemented locally in light-cone gauge, or partially implemented in the
presence of a Killing vector. Sources and the relation to Kaluza-Klein
monopoles are discussed.
