张量模型的背景:一个提议

Backgrounds from Tensor Models: A Proposal

Pablo Diaz

摘要:

虽然张量模型是量子引力理论的重要候选者,但到目前为止,它与经典时空的联系还很难找到。本文旨在填补这一空白,提出一个整洁的张量理论和欧几里得引力之间的联系在经典水平。与通常方法的主要区别是使用舒尔不变量(而不是单项不变量)作为流形伙伴。在这个新的设置中,经典时空特征可以在张量侧自然地被识别。局域性的概念是通过沃德恒等式出现的,在那里时空点之间的接近转化为杨图角之间的邻近。

英文摘要:

Although tensor models are serious candidates for a theory of quantum gravity, a connection with classical spacetimes have been elusive so far. This paper aims to fill this gap by proposing a neat connection between tensor theory and Euclidean gravity at the classical level. The main departure from the usual approach is the use of Schur invariants (instead of monomial invariants) as manifold partners. Classical spacetime features can be identified naturally on the tensor side in this new setup. A notion of locality is shown to emerge through Ward identities, where proximity between spacetime points translates into vicinity between Young diagram corners.
