$T^3$上极化Gowdy模型的圈量子化:经典理论

Loop Quantization of Polarized Gowdy Model on $T^3$: Classical Theory

Kinjal Banerjee, Ghanashyam Date

摘要:

真空高迪模型提供了许多研究,非平凡的midi超空间的例子。圈量子引力中的各种技术问题都可以在这些模型中进行研究,人们也可以希望在圈量子化中理解奇点及其分辨率。这个程序的第一步是以一种适合于循环量化的方式,用实连接变量重新表达模型。我们从非极化模型开始,并对极化情况进行了一致的简化。进行完全的规范固定,已知的溶液被回收。

英文摘要:

The vacuum Gowdy models provide much studied, non-trivial midi-superspace examples. Various technical issues within Loop Quantum Gravity can be studied in these models as well as one can hope to understand singularities and their resolution in the loop quantization. The first step in this program is to reformulate the model in real connection variables in a manner that is amenable to loop quantization. We begin with the unpolarized model and carry out a consistent reduction to the polarized case. Carrying out complete gauge fixing, the known solutions are recovered.
