齐型空间中Dirac方程的非对易积分

Noncommutative integration of the Dirac equation in homogeneous spaces

A. I. Breev, A. V. Shapovalov

摘要:

本文发展了齐次空间中Dirac方程的一种非对易积分方法。本文证明了具有不变度量的狄拉克方程等价于齐次空间变换李群上的一个方程组。这使我们能够有效地应用李群上的线性偏微分方程的非交换积分方法。这种方法不同于著名的分离变量的方法,并在某种程度上往往可以补充它的一般结构开发的方法说明了一个例子的齐次空间,不允许分离变量的狄拉克方程。然而,狄拉克方程的精确解的基础是由非交换积分方法显式构造的。同时,我们利用所发展的方法构造了三维deSitter时空$\mathrm{AdS_{3}}$中Dirac方程的一组新的完整精确解。得到的解决方案中发现的基本功能,这是非交换积分方法的特点。

英文摘要:

We develop a noncommutative integration method for the Dirac equation in homogeneous spaces. The Dirac equation with an invariant metric is shown to be equivalent to a system of equations on a Lie group of transformations of a homogeneous space. This allows us to effectively apply the noncommutative integration method of linear partial differential equations on Lie groups. This method differs from the well-known method of separation of variables and to some extent can often supplement it. The general structure of the method developed is illustrated with an example of a homogeneous space which does not admit separation of variables in the Dirac equation. However, the basis of exact solutions to the Dirac equation is constructed explicitly by the noncommutative integration method. Also, we construct a complete set of new exact solutions to the Dirac equation in the three-dimensional de Sitter space-time $\mathrm{AdS_{3}}$ using the method developed. The solutions obtained are found in terms of elementary functions, which is characteristic of the noncommutative integration method.
