So far, it is not well known how to deal with dissipative systems. There are many paths of investigation in the literature and none of them present a systematic and general procedure to tackle the problem. On the other hand, it is well known that the fractional formalism is a powerful alternative when treating dissipative problems. In this paper, we propose a detailed way of attacking the issue using fractional calculus to construct an extension of the Dirac brackets in order to carry out the quantization of nonconservative theories through the standard canonical way. We believe that, by using the extended Dirac bracket definition, it will be possible to analyze more deeply gauge theories starting with second-class systems.
到目前为止,如何处理耗散系统还不太清楚。文献中有许多研究途径,但没有一条能提供解决该问题的系统且通用的程序。另一方面,众所周知,分数阶形式体系在处理耗散问题时是一种强大的替代方法。在本文中,我们提出了一种详细的方法来解决这个问题,即使用分数阶微积分来构建狄拉克括号的扩展,以便通过标准的正则方法对非保守理论进行量子化。我们相信,通过使用扩展的狄拉克括号定义,将有可能从二类系统出发更深入地分析规范理论。
