耦合到无质量标量场的线性极化Gowdy模型的Hamilton动力学

Hamiltonian Dynamics of Linearly Polarized Gowdy Models Coupled to Massless Scalar Fields

J. Fernando Barbero G., Daniel Gómez Vergel, Eduardo J. S. Villaseñor

摘要:

本文的目的是详细分析耦合到无质量标量场的紧致Gowdy模型的哈密顿公式,作为实现量子化的必要的第一步。我们将特别关注物质的耦合,以及那些在三柄和三球拓扑中出现的特征,这些特征在研究得很好的三个环面的情况下不存在-特别是来自度量的正则性条件的极约束。作为我们分析的副产品,我们将得到一个替代的理解,在哈密顿框架内,这些模型的初始和最终奇点的外观。

英文摘要:

The purpose of this paper is to analyze in detail the Hamiltonian formulation for the compact Gowdy models coupled to massless scalar fields as a necessary first step towards their quantization. We will pay special attention to the coupling of matter and those features that arise for the three-handle and three-sphere topologies that are not present in the well studied three torus case -in particular the polar constraints that come from the regularity conditions on the metric. As a byproduct of our analysis we will get an alternative understanding, within the Hamiltonian framework, of the appearance of initial and final singularities for these models.
