The $\mathfrak{su}(2)$ spin $s$ representations via $\mathbb{C}{P}^{2s}$ sigma models

P. P. Goldstein, A. M. Grundland, A. M. Escobar Ruiz

We establish and analyze a new relationship between the matrices describing an arbitrary component of a spin $s$, where $2s\in {\mathbb{Z}}^{+}$, and the matrices of $\mathbb{C}{P}^{2s}$…
