摘要
We discuss black hole solutions with a Gauss-Bonnet term in the bulk and an induced gravity termon a thin brane of codimension-2. We show that these black hole scan be localized on the brane, and they can be extended further in to the bulk by a warp function. These solutions have regular horizons and no other curvature singularities appear apart from the string-like ones. The projection of the Gauss-Bonnet term on the brane imposes a constraint relation which dictates the form of matter on the brane and in the bulk.
