三维张量群场论的重正化SU(2)

Renormalization of an SU(2) Tensorial Group Field Theory in Three Dimensions

Sylvain Carrozza, Daniele Oriti, Vincent Rivasseau

摘要:

本文研究了三维空间中具有几何Boulatov型条件的SU(2)张量群场论(TGFT)的可重整化问题。我们证明,张量相互作用的程度6只是重正化没有任何异常。我们的新模型定义了Boulatov模型的可重正化TGFT版本,因此提供了一种新的方法来研究三维的量子引力。在本文建立的许多新的技术结果中,有一个具有规范不变性条件的可重整模型的一般分类,特别是关于Melonic图的性质,波函数重整化所需Melonic两点子图的二阶展开。

英文摘要:

We address in this paper the issue of renormalizability for SU(2) Tensorial Group Field Theories (TGFT) with geometric Boulatov-type conditions in three dimensions. We prove that tensorial interactions up to degree 6 are just renormalizable without any anomaly. Our new models define the renormalizable TGFT version of the Boulatov model and provide therefore a new approach to quantum gravity in three dimensions. Among the many new technical results established in this paper are a general classification of just renormalizable models with gauge invariance condition, and in particular concerning properties of melonic graphs, the second order expansion of melonic two point subgraphs needed for wave-function renormalization.
