In this short note, we will prove in a few steps that the new tetrads introduced previously in Einstein–Maxwell four-dimensional Lorentzian spacetimes, where gravitational and non-null electromagnetic fields are present, contain both the necessary information to provide the gravitational field and the necessary information to provide the electromagnetic field as well. These new tools thus become grand unification objects.

爱因斯坦-麦克斯韦四分体大统一

在这篇简短的笔记中，我们将通过几个步骤证明，之前在存在引力场和非零电磁场的爱因斯坦-麦克斯韦四维洛伦兹时空中引入的新四分体包含提供引力场的必要信息和提供电磁场的必要信息。这些新工具因此成为大统一的对象。
