Families of exact solutions of 4D higher-spin gravity with spherical, cylindrical and axial symmetry
Abstract:
I shall discuss the main aspects of certain families of exact solution of four-dimensional higher-spin gravity admitting at least two commuting Killing vectors. After reviewing some basics of Vasiliev's equations, I shall turn to describing how such solutions are constructed.
In particular, focussing on the spherically-symmetric ones, I shall highlight the algebraic and spacetime properties they share with gravitational black holes, and explain how, despite such similarities, their apparent curvature singularities may be resolved in higher-spin gravity.
