Higher-Spin Flat Space Cosmologies with Soft Hair

Ammon, Martin, Grumiller, Daniel, Prohazka, Stefan et al.

Understand

We present and discuss near horizon boundary conditions for flat space higher-spin gravity in three dimensions.

  • As in related work our boundary conditions ensure regularity of the solutions independently of the charges.
  • The asymptotic symmetry algebra is given by a set of $\hat{\mathfrak{u}}(1)$ current algebras.
  • The associated charges generate higher-spin soft hair.
