Zusammenfassung:
We analyse the constraints imposed by gauge invariance on higher-order
interactions between massless bosonic fields in three-dimensional higher-spin
gravities. We show that vertices of quartic and higher order that are
independent of the cubic ones can only involve scalars and Maxwell fields. As a
consequence, the full non-linear interactions of massless higher-spin fields
are completely fixed by the cubic vertex.
