研究了具有翘曲的六维Einstein-Maxwell轴对称模型中余维2奇点的正则化问题。这些奇点被位于对称轴周围的环状的余维-1膜所取代。我们假设存在一个具有Goldstone动力学的膜标量场，它产生了上述正则化成功所必需的特定结构的膜能量动量张量。我们在非超对称和超对称两种情况下研究了这些紧化。我们看到，在非超对称情况下，体规范场和膜标量场的允许翘曲以及量子数都受到限制。相反，在超对称的情况下，翘曲可以是任意的。
We study the regularization of the codimension-2 singularities in six-dimensional Einstein-Maxwell axisymmetric models with warping. These singularities are replaced by codimension-1 branes of a ring form, situated around the axis of symmetry. We assume that there is a brane scalar field with Goldstone dynamics, which is known to generate a brane energy momentum tensor of a particular structure necessary for the above regularization to be successful. We study these compactifications in both a non-supersymmetric and a supersymmetric setting. We see that in the non-supersymmetric case, there is a restriction to the admissible warpings and furthermore to the quantum numbers of the bulk gauge field and the brane scalar field. On the contrary, in the supersymmetric case, the warping can be arbitrary.
