  Conical brane singularities in six-dimensional flux compactification models
can be resolved by introducing cylindrical codimension-one branes with regular
caps instead of 3-branes (a la Kaluza-Klein braneworlds with fluxes). In this
paper, we consider such a regularized braneworld with axial symmetry in
six-dimensional Einstein-Maxwell theory. We derive a low energy effective
theory on the regularized brane by employing the gradient expansion approach,
and show that standard four-dimensional Einstein gravity is recovered at low
energies. Our effective equations extend to the nonlinear gravity regime,
implying that conventional cosmology can be reproduced in the regularized
braneworld.
