What is recorded here?
Aretakis established conserved horizon quantities for linear massless scalar waves on a class of smooth extremal axisymmetric black hole backgrounds and derived horizon non-decay; under additional geometric and decay conditions, higher transverse derivatives become unbounded. The extremal Kerr specialization gives explicit generic growth bounds.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Fixed-background linear scalar waves on the stated extremal geometries; the general derivative blow-up result has additional assumptions and the Kerr growth result uses a nonzero conserved horizon charge. This is not a proof of nonlinear gravitational instability or an astronomical observation.

Horizon instability of extremal black holes
Aretakis established conserved horizon quantities for linear massless scalar waves on a class of smooth extremal axisymmetric black hole backgrounds and derived horizon non-decay; under additional geometric and decay conditions, higher transverse derivatives become unbounded. The extremal Kerr specialization gives explicit generic growth bounds.
