Review: <strong>Representation</strong> <strong>Theory</strong> for<br />

Compact Lie Groups<br />

• SU(2) representation size: d= 2 j + 1,<br />

j = 0,½,1,…<br />

• j = 0, trivial<br />

• j= ½, d=2 fundamental representation, e.g.<br />

acted on by 2x2 matrices generated by Pauli<br />

spin matrices<br />

• j=1, d=3 Adjoint representation<br />
