Abstract

For both extremal and non‐extremal spherically symmetric black holes in theories with massless scalars and vectors coupled to gravity, we derive a general form of first‐order gradient flow equations, equivalent to the equations of motion. For theories that have a symmetric moduli space after a dimensional reduction over the timelike direction, we discuss the condition for such a gradient flow to exist.
