Wikipedia refers to that book...https://en.wikipedia.org/wiki/Representation_theory_of_SU%282%29 ... "Weights and the structure...

    Undergrad The irreducible representations of of su(2): Highest weight method

    Hi all I need to understand the following passage from Hall link page 78 : Some notation first: Basis for ##sl(2;C)##: ##H=\begin{pmatrix} 1&0\\0&−1\end{pmatrix} ;X=\begin{pmatrix} 0&1\\0&0\end{pmatrix} ;Y=\begin{pmatrix} 0&0\\1&0\end{pmatrix} ## which have the commutation relations...
