一类推广的Poincare群的群结构

Group Structure of an Extended Poincare Group

James Lindesay

摘要:

在以前的论文中,我们扩展了洛伦兹和庞加莱群,包括一组狄拉克助推器,给出了一个直接对应的一组发电机的自旋1/2系统是成比例的狄拉克矩阵。这些群对于发展自旋1/2系统以外的一般线性波动方程特别有用。在本文中,我们开发了显式的扩展庞加莱群的群属性,以获得群参数,这将是有用的物理计算系统,体现了群属性。包含时空平移将允许未来探索群结构中固有的规范属性。

英文摘要:

In previous papers we extended the Lorentz and Poincare groups to include a set of Dirac boosts that give a direct correspondence with a set of generators which for spin 1/2 systems are proportional to the Dirac matrices. The groups are particularly useful for developing general linear wave equations beyond spin 1/2 systems. In this paper we develop explicit group properties of the extended Poincare group to obtain group parameters that will be useful for physical calculations in systems which manifest the group properties. The inclusion of space-time translations will allow future explorations of the gauge properties inherent in the group structure.
