作为单个$^\ast$ -代数表示的量子场论

Quantum-field theories as representations of a single $^\ast$-algebra

Andreas Raab

摘要:

我们发现,许多著名的量子场论出现作为一个单一的$^\ast$ -代数表示。这些理论包括平坦和弯曲时空中的自由量子场论、格点量子场论、怀特曼量子场论和弦论。我们证明了这种理论可以在格上近似,并给出了格量子场论的连续极限的严格定义。

英文摘要:

We show that many well-known quantum field theories emerge as representations of a single $^\ast$-algebra. These include free quantum field theories in flat and curved space-times, lattice quantum field theories, Wightman quantum field theories, and string theories. We prove that such theories can be approximated on lattices, and we give a rigorous definition of the continuum limit of lattice quantum field theories.
