引入了适合球对称模型量子动力学的变量，进一步简化了球对称体积算子，并允许显式计算欧几里得和洛伦兹哈密顿约束下的所有矩阵元素。该结构完全符合环量子引力中完整理论和对称模型的量子化的一般方案。然后提出了在非均匀情况下整个方案的进一步一致性检查，进一步信任迄今为止主要在均匀模型中获得的物理结果。讨论了球对称模型在黑洞物理学中的新应用。
Variables adapted to the quantum dynamics of spherically symmetric models are introduced, which further simplify the spherically symmetric volume operator and allow an explicit computation of all matrix elements of the Euclidean and Lorentzian Hamiltonian constraints. The construction fits completely into the general scheme available in loop quantum gravity for the quantization of the full theory as well as symmetric models. This then presents a further consistency check of the whole scheme in inhomogeneous situations, lending further credence to the physical results obtained so far mainly in homogeneous models. New applications in particular of the spherically symmetric model in the context of black hole physics are discussed.
