代数量子场论的运算

Operads for algebraic quantum field theory

Marco Benini, Alexander Schenkel, Lukas Woike

摘要:

我们构造了一个着色运算,它的代数范畴是代数量子场论的范畴。这是通过一个依赖于一个范畴的选择的构造来实现的,这个范畴的对象提供操作数颜色,配备了一个我们称之为正交关系的附加结构。这使我们能够描述不同类型的量子场论,包括理论上的一个固定的洛伦兹流形,局部协变理论,也手征共形和欧几里得理论。此外,由于色算符函依赖于正交范畴,我们得到了不同类型量子场论范畴之间的关系。其中包括新颖而有趣的结构,如量子场论的时间分割和局部到全局的扩展。我们比较后者的Fredenis的普遍代数。

英文摘要:

We construct a colored operad whose category of algebras is the category of algebraic quantum field theories. This is achieved by a construction that depends on the choice of a category, whose objects provide the operad colors, equipped with an additional structure that we call an orthogonality relation. This allows us to describe different types of quantum field theories, including theories on a fixed Lorentzian manifold, locally covariant theories and also chiral conformal and Euclidean theories. Moreover, because the colored operad depends functorially on the orthogonal category, we obtain adjunctions between categories of different types of quantum field theories. These include novel and interesting constructions, such as time-slicification and local-to-global extensions of quantum field theories. We compare the latter to Fredenhagen's universal algebra.
