explicit matrix example of irreducible representation of s0(3)

247 Views Asked by At

Can someone give me a concrete or an explicit example of an irreducible representation of the Lie algebra so$(3)$? I know they are given by the Wigner D matrices but I want an explicit example of such a matrix and if possible how to compute it.

V. M. Gordienko: Matrix entries of real representations of the group $O(3)$ and $SO(3)$, Siberian Mathematical Journal (2002), 43(1):36-46, doi: 10.1023/A:1013816403253

describes the construction of the real representations of the Lie group $SO(3)$ using homogeneous polynomials. From those the corresponding representation matrices of the Lie algebra $\mathfrak{so}(3)$ can be derived, see here and there for explicit examples in dimension 5 and 7.
