环量子引力的新背景独立表示

Towards new background independent representations for Loop Quantum Gravity

Madhavan Varadarajan

摘要:

最近,圈量子引力中的表示的唯一性定理被构造出来。我们通过削弱所谓的LOST唯一性定理的假设来探索交替表示的存在性。弱化后的假设似乎在物理上是合理的,并保留了明确的背景独立性的关键要求。为了简单起见,我们将注意力限制在规范群U(1)的情况。

英文摘要:

Recently, uniqueness theorems were constructed for the representation used in Loop Quantum Gravity. We explore the existence of alternate representations by weakening the assumptions of the so called LOST uniqueness theorem. The weakened assumptions seem physically reasonable and retain the key requirement of explicit background independence. For simplicity, we restrict attention to the case of gauge group U(1).
