Query: Lovelock solutions in the presence of matter sources   For a large class of space and time-dependent warped geometries we find the
general solution of the 6-dimensional Einstein-Gauss-Bonnet equations in the
presence of p-form matter fields. This is done under two conditions on the
matter sector which we show impose the integrability of the full system.
Solutions are classified and known black hole limits are found. It is shown
that Lovelock gravity restricts drastically the possible horizon geometries and
allowed matter sources. In fact, we show that if we allow only for solutions of
asymptotically flat falloff behaviour, and no fine-tuning of coupling
constants, then the only permissible black hole is that of Boulware-Deser with
electromagnetic charge. The situation of 6 dimensional Lovelock gravity is
therefore almost identical to 4 dimensional General Relativity. The
gravitational horizon constraints lead us to find static solutions involving
3-form matter fields in anti de-Sitter space which are also new to General
Relativity along with other cosmological and black string type of solutions.
