用投影技术构造场论的运动量子态空间

Construction of spaces of kinematic quantum states for field theories via projective techniques

Andrzej Okolow

摘要:

本文提出了一种构造场论量子态空间的方法:给定场论的相空间,先定义一族具有有限自由度的物理系统,然后为每个有限系统定义一个量子态空间,最后利用射影技巧将所有这些空间组织成一个对应于原相空间的量子态空间.这种构造是运动学的,在这个意义上,它仅仅基于相空间的结构,而不考虑对空间的可能约束。该构造是Kijowski构造的推广-后者仅限于线性相空间的理论,而前者则不受此限制。

英文摘要:

We present a method of constructing a space of quantum states for a field theory: given phase space of a theory, we define a family of physical systems each possessing a finite number of degrees of freedom, next we define a space of quantum states for each finite system, finally using projective techniques we organize all these spaces into a space of quantum states which corresponds to the original phase space. This construction is kinematic in this sense that it bases merely on the structure of the phase space and does not take into account possible constraints on the space. The construction is a generalization of a construction by Kijowski - the latter one is limited to theories of linear phase spaces, while the former one is free of this limitation.
