Schwinger-Dyson Equation in Three-Dimensional Simplicial Quantum Gravity,he Turaev-Viro invariant, we introduce boundary operators in the simplicial gravity associated to compact orientable surfaces. An amplitude of the boundary operator is given by a sum over triangulations in the interior of the boundary surface. It turns out that the amplitude solves the Schwinger-Dys作者: 名字 時間: 2025-3-22 01:48
