Thermodynamics of black holes immersed in EMD-like electrovacua

Determine whether the approach that derives black-hole thermodynamics without constructing explicit black-hole solutions can be applied to black holes immersed in electrovacua in Einstein-Maxwell-dilaton-like theories.

Background

The paper notes that its solutions are primarily local and that their global structure remains to be investigated. It then identifies a broader unresolved question: whether recently proposed methods for deriving black-hole thermodynamics without explicit solution construction extend to black holes placed in electrovacua of Einstein-Maxwell-dilaton-like theories.
