在非平凡拓扑中,具有平坦共动三维空间的宇宙的量子创生是可能的。对于3-torus拓扑,计算了在de Sitter(暴胀)阶段具有有限3-体积的空间平坦的各向同性世界的量子诞生的相对概率,允许无质量量子场的真空能量-动量张量,这将导致拓扑的非平凡性。
Quantum creation of a universe with flat comoving 3-space is possible in nontrivial topology. For 3-torus topology, the relative probability of quantum birth of a spatially flat, isotropic world having finite 3-volume during the de Sitter (inflationary) stage is calculated, allowing for the vacuum energy-momentum tensor of massless quantum fields that will result from the nontriviality of the topology.
