Identity in Transformation Groups
In the context of transformation groups, such as the General Linear Group ($\mathrm{GL}(n, \mathbb{R})$) or the Lorentz Group, the identity transformation is the null operation. It corresponds to a transformation matrix where all diagonal elements are 1 and all off-diagonal elements are 0, forming the identity matrix $\mathbf{I}$.
For a Lorentz transformation $\Lambda$…
