When relativistic quantum mechanics and field the- ory emerged, the half-integer internal angular momentum was interpreted in terms of the complex special linear group SL(2, C ) as

Using a poset fiber theorem, it is proved that the order ideal of this poset generated by the Coxeter elements is homotopy Cohen–Macaulay.. This method results in a new proof
