Adjoint representation: Definition, Properties & Variants and analogues

In mathematics, the adjoint representation (or adjoint action) of a Lie group G is a way of representing the elements of the group as linear transformations of the group's Lie algebra, considered as a vector space. For example, if G is G L ( n , R ) {\displaystyle \mathrm {GL} (n,\mathbb {R} )} , the Lie group of real n-by-n invertible matrices, then the…
