Query: Magnetic Branes in Third Order Lovelock-Born-Infeld Gravity   Considering both the nonlinear invariant terms constructed by the
electromagnetic field and the Riemann tensor in gravity action, we obtain a new
class of $(n+1)$-dimensional magnetic brane solutions in third order
Lovelock-Born-Infeld gravity. This class of solutions yields a spacetime with a
longitudinal nonlinear magnetic field generated by a static source. These
solutions have no curvature singularity and no horizons but have a conic
geometry with a deficit angle $\delta$. We find that, as the Born-Infeld
parameter decreases, which is a measure of the increase of the nonlinearity of
the electromagnetic field, the deficit angle increases. We generalize this
class of solutions to the case of spinning magnetic solutions and find that,
when one or more rotation parameters are nonzero, the brane has a net electric
charge which is proportional to the magnitude of the rotation parameters.
Finally, we use the counterterm method in third order Lovelock gravity and
compute the conserved quantities of these spacetimes. We found that the
conserved quantities do not depend on the Born-Infeld parameter, which is
evident from the fact that the effects of the nonlinearity of the
electromagnetic fields on the boundary at infinity are wiped away. We also find
that the properties of our solution, such as deficit angle, are independent of
Lovelock coefficients.
