Query: Non-extremal branes   We prove that for arbitrary black brane solutions of generic Supergravities
there is an adapted system of variables in which the equations of motion are
exactly invariant under electric-magnetic duality, i.e. the interchange of a
given extended object by its electromagnetic dual. We obtain thus a procedure
to automatically construct the electromagnetic dual of a given brane without
needing to solve any further equation. We apply this procedure to construct the
non-extremal (p, q)-string of Type-IIB String Theory (new in the literature),
explicitly showing how the dual (p, q)-five-brane automatically arises in this
construction. In addition, we prove that the system of variables used is
suitable for a generic characterization of every double-extremal Supergravity
brane solution, which we perform in full generality.
