论文摘要
不确定的因果结构通常存在于量子重力理论中，该理论承认路径积分制剂。我们表明，对因果结构的总结消除了物质QFT的紫外线分歧，并使用非扰动世界量子重力方法解决了时空奇异性。独立的信息理论和非依赖性的考虑表明，无限期因果结构的紫外线正规化机制也适用于其他量子重力理论。
Indefinite causal structure is generically present in theories of quantum gravity admitting a path integral formulation. We show that summing over causal structures eliminates ultraviolet divergences of matter QFT and resolves spacetime singularities using the non-perturbative World Quantum Gravity approach. Independent information-theoretic and model-independent considerations suggest that the mechanism of ultraviolet regularization by indefinite causal structure also applies to other theories of quantum gravity.
