摘要

马约拉纳变换使托马斯-费米方程简化为一阶微分方程成为可能。托马斯-费米方程在同调变换下的特殊缩放特性使这种还原成为可能。这种还原在恒星天体物理学中是众所周知的，在恒星天体物理学中，使用同构不变变量早已被证明是有用的。我们在托马斯-费米方程中使用同构不变变量来揭示神秘的马约拉纳变换的起源。

Majorana transformation of the Thomas–Fermi equation demystified

The Majorana transformation makes it possible to reduce the Thomas–Fermi equation to a first-order differential equation. This reduction is possible due to the special scaling property of the Thomas–Fermi equation under homology transformations. Such reductions are well known in the context of stellar astrophysics, where the use of homology-invariant variables has long proved useful. We use homology-invariant variables in the context of the Thomas–Fermi equation to demystify the origin of the otherwise mysterious Majorana transformation.
