Query: Constructing black holes in Einstein-Maxwell-scalar theory   Exact black hole solutions in the Einstein-Maxwell-scalar theory are
constructed. They are the extensions of dilaton black holes in de Sitter or
anti de Sitter universe. As a result, except for a scalar potential, a coupling
function between the scalar field and the Maxwell invariant is present. Then
the corresponding Smarr formula and the first law of thermodynamics are
investigated.
