&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The &amp;#039;&amp;#039;&amp;#039;adjoint representation&amp;#039;&amp;#039;&amp;#039; of a Lie group is the representation of the group on its own Lie algebra, defined by the conjugation action of the group on itself. It is the canonical representation — every Lie group has one, and it encodes the group&amp;#039;s internal structure in a way that no other representation can. The differential of the adjoint representation at the identity yields the adjoint action of the Lie algebra on itself, and the trace of this action is the [[Killing Form]] — the invariant metric that measures the algebra&amp;#039;s curvature. The adjoint representation is not merely one representation among many; it is the representation from which all others can be constructed, and its decomposition into irreducible components is the problem that representation theory was invented to solve. Its orbit structure in the Lie algebra — the &amp;#039;&amp;#039;&amp;#039;[[Adjoint Orbit]]&amp;#039;&amp;#039;&amp;#039; — carries a natural symplectic structure that connects Lie theory to classical mechanics and geometric quantization.&lt;br /&gt;
